Building on Tradition

Founded 120 years ago, Viega is a privately owned international group of companies. In the United States, Canada, Mexico, and Latin America, Viega specializes in plumbing, heating, and pipe-joining technologies. The values of Viega’s founder, Franz-Anselm Viegener, are just as present today as they were when he started the company in 1899. Courage, passion, and innovative spirit are still the basics of Viega’s foundation.

At Viega, Safety Is a Priority.

Safe, certain, and secure, Viega fittings are designed for peace of mind.

  1. In MegaPress stainless fittings, the 420 stainless steel grip ring’s teeth cut into the pipe and lock the fitting securely in place.
  2. For ½” to 2″ fittings, a 304 stainless steel separator ring protects the sealing element from damage by creating a positive physical separation during installation. For 2½” to 4″ fittings, a PBT (Polybutylene Terephthalate) separator ring protects the sealing element.
  3. The FKM sealing element in MegaPress 304/316 FKM fittings and the EPDM sealing element in MegaPress 316 fittings ensure watertight or airtight connections.

In all MegaPress stainless fittings, Viega’s unique Smart Connect technology helps installers ensure that they have pressed all connections.

DANGER!

Introduction

MegaPress Stainless Systems

Viega MegaPress stainless systems can help reduce installation time by up to 90 per cent compared to traditional methods of pipe joining. Soldering and welding can be messy and time-consuming, and connections are not always reliable. With Viega press technology, installers can make consistent, secure press connections in a matter of seconds, without flame or heavy equipment. The fittings require no soldering or welding and are installed with electrohydraulic press tools (battery-powered or corded press tools). Viega MegaPress stainless fittings can be customized for a wide variety of applications in industrial, commercial, or residential projects.

Fire Protection You Can Count On

With FM and UL certification for MegaPress ½” to 2″ sizes, with 2½” to 4″ sizes soon to be added to the listing, Viega is introducing the latest press system for the fire protection market. Viega MegaPress 304 FKM and 316 fittings can be used in prefabricated assemblies, producing a straight, clean installation. Backed by a written limited warranty and approved for NFPA 13, 13D, and 13R fire sprinkler systems, MegaPress stainless can be installed in industrial applications or commercial projects like hotels and dorms. With Viega’s cold-press technology, installations in attics and tight corners are safer than with traditional joining methods. Installers don’t need to carry heavy equipment or bother with metal shavings or cutting oils.

  • It is the responsibility of the installer or any other parties to adhere to all applicable local rules and regulations governing the nature of the installation.
  • The use of the system for applications other than those listed or outside of these parameters must be approved by Viega Technical Support (techsupport@viega.us).

Smart Connect Technology – Security Under Pressure

Locating unpressed connections is an important step in the pressure-testing process. Viega MegaPress stainless includes Smart Connect technology, providing quick and easy identification of unpressed connections during a pressure test. Smart Connect technology is an integral part of the design of the fitting, providing a path for liquids and/or gases from inside the system past the sealing element of an unpressed connection. When pressed according to our Product Instructions, the fluid path is altered, creating a reliable, leakproof connection. Unpressed connections are located by pressurizing the system with air or water. When testing with water, the proper pressure range is 15 to 85 psi. Pressure testing with air can be dangerous at high pressures. When testing with compressed air, the proper pressure range is ½ to 45 psi. Following a successful Smart Connect test, the system may be pressure tested up to 600 psi maximum for water and 200 psi maximum for air if required by local code requirements.

Testing for unpressed connections using Smart Connect is not a replacement for pressure-testing requirements of local codes and standards.viega-Megapress-

Sealing Element Description

FKM Sealing Element

MegaPress 304 and 316 FKM press fittings are manufactured with an FKM sealing element installed at the factory. FKM is well known for its excellent resistance to petroleum products and solvents as well as for its exceptional high-temperature performance, which makes it ideal for seals and gaskets in solar, district heating, low-pressure steam, and compressed-air systems.

  • Definition: FKM Fluoroelastomer, dull black in color
  • Maximum Pressure: 200 psi
  • Operating Temperature: 14°F to 284°F (with temperature spikes up to 356°F)

The FKM sealing element is a special-purpose elastomer typically installed where higher temperatures are required. It possesses excellent resistance to aging, ozone, sunlight, weathering, environmental influences, and oils and petroleum-based additives.

EPDM Sealing Element
MegaPress 316 press fittings are manufactured with an EPDM sealing element installed at the factory. The EPDM sealing element is used mainly for potable water, hydronic heating, low pressure steam, fire sprinkler, and compressed- air installations.

  • Definition : EPDM Ethylene-Propylene-Diene-Monomer, gloss black in color
  • Maximum Pressure: 200 psi
  • Operating Temperature: 0°F to 250°F

The EPDM sealing element is a synthetically manufactured and peroxidically cross-linked, general-purpose elastomer with a wide range of applications. It is resistant to aging, ozone, sunlight, weathering, environmental influences, chemicals, and most alkaline solutions. The EPDM sealing element is used mainly in the applications of hydronic heating, chilled water, and fire sprinkler installations. It is not resistant to hydrocarbon solvent solutions, oils, chlorinated hydrocarbons, turpentine, or gasoline.

No-Stop Couplings

No-stop couplings and extended no-stop couplings are often used to conduct repairs. Without a stop, these couplings can slide completely onto a pipe and allow a connection to be made in tighter spaces. Unlike fittings with an integrated stop that have a minimum insertion depth, no-stop couplings have minimum and maximum allowable insertion depths.

Welding

The following requirements must be considered when welding in the same vicinity as Viega MegaPress stainless fittings.

Welding Requirements

The installer should take precautions to keep the MegaPress stainless connection cool:

  • Wrap the connection with a cold, wet rag.
  • Protect the connection with a weld blanket.
  • Prefabricate solder connections/welded fittings prior to installing the press fitting. (Ensure pipe has cooled before installing the press fitting.)
  • Apply heat sink gel or spray or spot freezing.

Welding Adjacent to a Press Fitting

To prevent damage to the sealing element, maintain proper welding distances from the fitting. If welding adjacent to the connection, weld a minimum of four inches away. Welding in Line With a Press Fitting To prevent damage to the sealing element, maintain proper welding distances from the fitting. If welding in line with the connection, weld a minimum of three feet away from the connection to protect the sealing element.

General Installation Notes

Expansion

Thermal expansion in installed systems generates stress on pipes and appliance connectors. Compensation must be allowed for expansion and contraction that may occur within the piping system. Expansion joints or mechanical expansion compensators may be used to alleviate these stresses.
Electrical Bonding When properly installed, MegaPress stainless fittings comply with Section 1211.15 Electrical Bonding and Grounding of the Uniform Plumbing Code. The mechanical press provides continuous metal-to-metal contact between fitting and pipe. The press ensures the continuity of the bonding through this contact.

DANGER!

Electric Shock

An electric shock can cause burns, serious injury, and even death.

  • Because all metallic piping can conduct electricity, unintentional contact with a live wire can cause the entire system and components connected to it to become energized. Metal piping is not meant to conduct electricity.
  • A properly bonded system creates a safe path for electricity to travel so that the system can’t be energized.
  • An unbonded or improperly bonded system can be a shock hazard.
  • Always ensure that bonding is in accordance with local codes.

Concealed Spaces

The Viega MegaPress Stainless fitting system has been approved for use in concealed spaces. Specific performance tests were conducted to evaluate the fittings for use in concealed spaces. Concealed pipe and fittings shall be protected from puncture threats. PG-MP 724701 1023 MegaPress Stainless Systems

Exposure to Freezing Temperatures

Viega MegaPress 316 systems with EPDM sealing elements can be installed in ambient temperatures down to 0°F. The FKM sealing element available with Viega MegaPress 304 and 316 FKM fittings can be installed in ambient temperatures down to 14°F. When the contents could freeze, piping must be protected per acceptable engineering practices, codes, and as required by local code.

Underground Installations

Viega MegaPress stainless fitting systems and stainless pipe are approved for underground installations. However, installations must meet all state and local codes, including those for underground. Proper authorization must be obtained from the Authority Having Jurisdiction prior to installation.

Corrosion Protection

Viega MegaPress stainless fittings exposed to corrosive action, such as soil conditions or moisture, must be protected in an approved manner in accordance with NACE Standard RP0169-2002 Section 5, 2009 UPC Chapter 6 Section 609.3.1, 2009 UMC Chapter 13 Section 1312.1.3, and in a manner satisfactory to local code requirements. Care should be taken to select hangers of suitable material that is galvanically compatible with the piping system. In addition, systems should be properly sized to minimize the risk of erosion-corrosion resulting from excessive velocities.

Pressure Surges

  • Pressure surges or transients from fast-acting valves, pump surges, and other sources that result in water hammer may cause damage to many system components, including press fittings.
  • When fast-acting valves and/or pumps are incorporated into a system, the designer and installer should isolate press fittings from sharp pressure surges.

Transition Fittings – Threaded

Viega MegaPress stainless systems can be joined with off-the-shelf threaded fittings made of non-ferrous metals. In this regard:

  • The threaded connection is made first.
  • The press connection is made second. This process avoids unnecessary torsion on the press fitting.

Transition Fittings – Flange

When using Viega flanges, bolt the flange end in place prior to pressing the fitting to the pipe.

Rotating a Pressed Fitting

Once a MegaPress stainless fitting has been pressed, it can be rotated (not by hand), but once rotated more than five degrees, the fitting should be re- pressed to restore resistance to rotational movement.

Deflection

The pressing process can cause deflection (angular misalignment) to occur. When pressing Viega MegaPress stainless fittings in a system, the deformation of the fitting is constant. This allows for a consistent leak-free joint every time and is a result of the pressing technique. Deflection occurs in the same way for every fitting. The fitting being pressed will move in the direction of the jaw or ring opening.

  • Since the fitting will deflect toward the opening of the jaw or ring, the pipe end will deflect in the opposite direction.
  • By counteracting the fitting movement, one can minimize the deflection of the fitting and ultimately the pipe.
  • When using strut and clamps, deflection is minimized and nearly eliminated, depending on clamp spacing.

Controlling Deflection

Deflection while pressing can be minimized by utilizing the following installation practices.

Alternate Press Directions

  • Press one end of fitting.
  • Make second press on other end of fitting from the opposite side.

Push-Pull Method

  • Rings = Push on press tool.
  • Jaws = Pull-on press tool.

The press tool can be feathered using the trigger as needed to apply pulling or pushing force to control deflection.

Re-Press

  • Press the fitting, once on each side (that is, re-press the fitting a second time on the opposite side).
  • Pressing the same connection from the opposite side will usually straighten the misalignment between the pipe and fitting.
  • When pressing overhead piping, it may be inconvenient to alternate sides for each press.
  • The natural weight of the piping plus pressing on opposite sides at a
    • The 45-degree angle should adequately eliminate deflection.
  • This technique can also be used for any horizontal piping and when working above the piping.

Tool Clearances

Minimum distances should be taken into consideration during planning in order to avoid space constraints during installation. Ensure that the space required for system pressing tools is available if Viega MegaPress stainless fittings will be installed immediately upstream or downstream from wall or floor penetrations.

Frequently Asked Questions

  • What is Smart Connect technology?
    • Smart Connect technology provides a quick and easy way to identify unpressed connections during the pressure-testing process. Unpressed connections are located by pressurizing the system with air or water. When testing with water, the pressure range is 15 psi to 85 psi maximum. When testing with air, the pressure range is ½ psi to 45 psi maximum. The flow path is removed during the pressing process, creating a leakproof, reliable connection. Guaranteed.
  • Why is Smart Connect technology so valuable?
    • Smart Connect technology gives the user strong peace of mind. It allows for faster testing procedures since you do not have to shut down and drain the system. Costly damages and possible insurance claims and premiums can be avoided because it identifies unpressed connections before they can become a problem. Because of the time savings, projects stay on track.
  • Do I need additional equipment to install Viega MegaPress  Stainless systems?
    • No. Viega designed Viega MegaPress Stainless fittings to be compatible with the same jaws and press tools that are used for the Viega MegaPress carbon steel systems.
  • If a leak is discovered, is it necessary to drain the system  prior to pressing the connection?
    • No. It is not necessary to drain the system when making a repair.
  • How would an inspector know they are looking at a good connection?
    • Good connections can be proven by performing a pressure test, using the same procedure for a fitting system.
  • What is the lubrication used on the sealing elements?
    • The sealing elements are lubricated with a USDA approved H1 lubricant, meeting the requirement of FDA 21CFR. If it is necessary to lubricate the seals in the field, use water only. Do not use petroleum-based lubricants. Petroleum and EPDM are incompatible.
  • How long will the EPDM seal last?
    • When properly installed, the EPDM seal and connection will last as long as the piping system.
  • How do I fabricate a system in tight places when using Viega  MegaPress?
    • If necessary, prefabricate connections that are in tight places and then install.
  • What is the warranty for Viega MegaPress Stainless fittings?
    • Viega MegaPress stainless fittings carry a two-year warranty against defects in material and workmanship from Viega.
  • How do Viega MegaPress stainless connections hold up to freezing temperatures?
    • Precautions should be taken for any piping system to protect the system from below-freezing temperatures.
  • What level of turbulence occurs in Viega MegaPress Stainless  fittings, and will it cause premature wear in the piping?
    • The long radius of Viega MegaPress elbows reduces turbulence typically experienced with traditional short-radius fittings. Not reaming the ID of the pipe is the largest contributing factor to turbulence and premature wear of any piping system.
