Choose the No-Hub Coupling with the patented shield design that provides maximum transfer of pressure from the clamps - to the gasket - to the pipe. Engineered to connect no-hub cast iron pipe in applications replacing the less-efficient hub and spigot.
Patented Bi-Directional Shield Design
The shield will adjust to variations in diameters and circumferences of the pipes being joined, thereby eliminating leak paths. The patented, bi-directional corrugations exert sealing pressure in both parallel and transverse patterns on the gasket and pipe, providing a positive, reliable seal.
Specially Beaded Gasket
Made of an elastomeric compound that meets the requirements of ASTM C564 and features a series of strategically positioned grooves and beads. When tightened, the shield mates with
these grooves and beads to exert exceptional sealing pressure and holding power to prevent
“pull out” failures.
Interlocking Clamp Design
The clamps feature a one-piece screw housing that mechanically interlocks the housing to the
band. This one-piece housing design eliminates leak paths that can occur in staked or welded
clamps.
Floating Eyelet Design
Floating eyelets fasten the clamps to the shield, allowing the clamp band and shield to move
independently. This freedom prevents the shield from crimping during tightening, which can lead to leakage later on.
Specifications
Standard No-Hub
5/16” hex-head screw applies 60 in.-lbs. of installation torque to the band/shield assembly.
Standard No-Hub Couplings conform to CISPI 310. Couplings comply with ASTM C 1277. Gaskets are made from an elastomeric compound that meets the requirements of ASTM C 564.
Medium Duty No-Hub
The distinctive yellow shield quickly identifies the Heavy-Duty MD Couplings and makes it
easier for inspectors. 5/16” hex-head screw applies 80 in.-lbs. of installation torque to the
band/shield assembly.
Medium Duty No-Hub Couplings conform to CISPI 310. Couplings comply with ASTM C 1277. Gaskets are made from an elastomeric compound that meets the requirements of ASTM C 564.
Heavy Duty No-Hub
The distinctive green shield quickly identifies the Heavy-Duty HD Couplings and makes it easier for inspectors. 3/8” hex-head screw applies 80 in.-lbs. of installation torque to the band/shield assembly. Boasts an ultimate torque rating exceeding 100 in.-lbs. and heavier gauge stainless steel.
Heavy Duty No-Hub Couplings conform to CISPI 310, Factory Mutual CN 1680, ASTM C 1540. Gaskets are made from an elastomeric compound that meets the requirements of ASTM C 564.
