½” – 1½” Fitting Installation Instructions
For ASTM A53, A106, A135, A795 (schedule 10 to 40) carbon steel pipe in 1/2” to 1%” sizes
-
Select clean, undamaged pipe and cut to desired length. Cut tube end square using a pipe cutter or fine-toothed steel saw. If using a vise or other method to hold the pipe, do not damage the pipe section which is inserted into the fitting. Scratches or deformed pipe may result in an improper seal.
-
Prep pipe to a smooth and even surface with a fine grit sandpoper. The surface should be free of indentations, oil, and debris. Do not use engraved or stamped pipe. Indentations in the pipe may result in an im- proper seal. To avoid damage to the O-ring, the pipe must be free of burrs and sharp edges.
-
Visually inspect the fitting to ensure the grip ring, separator ting, and seal are in place, clean and, free of contaminants. Only original NIBCO yellow HNBR Bench PressG™ seals are to be used.
-
Mark the pipe to the proper insertion depth as indicated by the Insertion Depth Chart. Im- proper insertion depth may result in on improper seal.
-
Fully insert the pipe into the fitting. For fittings with stops, insert the pipe to make contact with the fitting stop. For fittings without o stop, insert the pipe to a depth no less than the specified insertion depth. Improper insertion depth may result in an improper seal. If necessary, the O-ring may be lubricated with water. Never use oils or lubricants as these can degrade or damage the sealing element.
-
Ensure the proper press jow is installed in the pressing tool. Squeeze the jaw arms to open the jaw set. Place open jaws around the fitting end and ensure the jaw is properly aligned with the contour of the fitting. When using the ring and actuator instead of jaws, use the correct size ring an appropriate actuator. See NIBCO Tool and Jaw Compatibility Matrix for approved tools and jaws.
-
Make sure the pipe is inserted to the proper depth. With the tool square to the axis of the pipe, start pressing procedure. After the press is complete, remove the jaw from the fitting.

WARNING
Read press tool operator’s manual and fitting manufacturer’s installation
instructions before using. Failure to follow all instructions may result in
extensive property damage and/ or serious personal injury. Call the NIBCO
Technical Service Department at 1.888.446.4226 if you have any ques-tions or
need assistance.
Notes:
- To ensure a proper press, maintain the specifi ed minimum distance between fi ttings. The pressing jaw must have clearance to the adjacent fi tting. Failure to maintain the minimum specifi ed distance may result in an improper seal.
- A minimum distance to welds must always be maintained.
A minimum of 4 inches must be maintained when welding adjacent to a BenchPressG fi tting and a minimum of 3 feet must be maintained when welding in-line. The following precautions should be used to protect the BenchPress fitting:
- Wrap the press fi tting connection with a cold wet rag
- Protect the press fi tting connection with a weld blanket
- Fabricate weld connections prior to installing the press fi tting

maximum pressure is 15 psi. Following a successful leak test, the system may
be pressure tested up to 200 psi if required by local code requirements or
project specifications. Leak testing with air can be dangerous at high
pressures.
The following standards, codes, and instructions should be followed when
installing NIBCO ® BenchPressG TM fittings for fuel gas:
- The installation of the fuel gas system shall be made in accordance with local codes, or in the absence of local codes, in accordance with the National Fuel Gas Code NFPA 54, the LP-Gas Code NFPA 58 as application.
- For use with ASTM A53, A106, A795 and A135 carbon steel pipe.
- Undue stress or strain on the fittings and the tubing is to be avoided.
- Concealed pipe and fittings shall be protected from puncture threats.
- If the installation requires components in addition to those supplied by the fitting manufacturer, those components shall be The instructions shall state that only the components provided or specified by the manufacturer are to be used in the installation.
- The fitting/pipe system shall not be used as a grounding electrode for an electrical system.
- The inspection, testing and purging of the installation shall be performed using procedures specified in Part 4 of the National Fuel Gas Code NFPA 54, ANSI Z223.1, the LP-Gas Code NFPA 58 section 3.2-10 as applicable or in accordance with the requirements of the applicable local codes.
- For use with natural, propane, mixed, and manufactured gasses in the vapor state, not in the liquid state.
- The fitting/pipe system shall not be used as a means of support.
