ALPHA Tee Restrained Fitting

Features
PAGE 1-2

Wide Range Restrained Coupling
ORIGINALLY RELEASED IN THE SUMMER OF 2013, THE ALPHA COUPLING INSTALLS IN ABOUT THREE MINUTES, AND ACCOMMODATES UP TO 8 DEGREES OF DEFLECTION (4 DEGREES ON EACH END). PAGE 1-4

Wide Range Restrained Flanged Coupling
THE ALPHA FLANGED COUPLING QUICKLY ADAPTS PLAIN-END PIPE TO FLANGED FITTINGS. THE ALPHA FLANGED COUPLING ALSO ACCOMMODATES FLANGED SPOOL PIECES FOR CONNECTING TO VALVES AND
OTHER FITTINGS. PAGE 1-9

Wide Range Restrained End Cap
THE ALPHA EC CAPS PLAIN-END PIPE FOR TESTING, BLOW-OFF OR LINE FLUSHING. THE ALPHA END CAP CAN ALSO BE USED AS A RELIABLE PIPE END SEAL FOR PERMANENT INSTALLATION. PAGE 1-7

Wide Range Restrained Tee Fitting
ALPHA TEE RESTRAINED FITTINGS QUICKLY ADD A BRANCH CONNECTION OFF A MAIN LINE AND ARE FASTER TO INSTALL THAN A TRADITIONAL AWWA C153 MJ TEE. PAGE 1-11

ALPHA ADVANTAGES

Standard Alpha covers IPS PVC through Ductile Iron pipe diameters.
Alpha XL accommodates Ductile Iron through Oversize Cast Iron pipe sizes.
Alpha can be configured to transition from IPS PVC up to Oversize Cast Iron pipe diameters.
One piece, stab-fit installation.
Cast components are high strength ductile iron.
Working pressure: up to 350 PSI.
Manufactured in the U.S.A.
US Patent: 8,894,100 & 9,534,714
Alpha products are approved for use on:

Ductile iron

Cast iron (Classes A, B, C & D)

PVC IPS size (Sch 40, Sch 80 & SDR 21)

PVC C900 and C909

HDPEsize4″-12″:SDR9,11,13.5&17,nopipestiffenersrequired.

For other pipe materials, contact Romac.
NOTE: The 16″ Alpha XL is not compatible with HDPE and the original Alpha (with black grippers) is not compatible with HDPE pipe.

INSTALLATION TIME IS A FRACTION OF OTHER RESTRAINT METHODS

KEY ALPHA COMPONENTS

HOW ALPHA WORKS

Alpha is positioned over the pipe gap.
Nuts are tightened, rotating the end ring.
Draw hooks pull gasket and grippers outward and against the pipe.
Gaskets compress and seal against the pipe surface. Gripper teeth are set.

MATERIAL SPECIFICATIONS

CASTINGS: All cast components (end rings, center ring and bolt guides) are ductile iron, meeting or exceeding the requirements of ASTM A536, grade 65-45-12.
GRIPPERS: Ductile (nodular) iron, meeting or exceeding ASTM A536, grade 65-45-12. Machine sharpened and heat treated. Xylem 1424 coated for corrosion protection.
GASKET: SBR compounded for water and sewer service in accordance with ASTM D2000. NBR available upon request.
NSF/ANSI 61 & 372 Certified.
STANDARD ALPHA FITS IPS PVC THROUGH DUCTILE IRON PIPE OD’S.
DRAW-HOOK FASTENERS: 304L stainless steel.
RAMP RUNNERS: Reinforced nylon.
BOLTS & NUTS: 304 stainless steel, 5/8-11 bolts with heavy hex e-coated nuts. Fasteners provided with anti-galling protection.
