Restraining


RCT Flex-Tite Fittings

Revelation Connection Technology (RCT) Flex-Tite Fittings are a new self-restrained fitting with an integral restraining gasket. This fitting eliminates the need for external restraint devices that are labor intensive and are prone to corrosion. It teams the strength of ductile iron with the non-corrosive benefits of an internal self-restraining gasket in an easy-to-install push-on fitting. Flex-Tite fittings are designed to be used on AWWA C900/C909 DR-14, -18 or -25 pipe in 4-inch through 12-inch diameters.

Pipe-Lock Joint Restraint Couplings

Smith-Blair Pipe-Lock Joint Restraint Couplings are fabricated steel sleeve restraint couplings that can be used to connect and restrain plain end pipe to plain end pipe.

AWWA M-11 Harness Style Assemblies

Smith-Blair Harness Assemblies should be used where calculations show the forces resulting from a lateral connection, change in direction of the pipeline, unstable soil, thermal expansion/contraction or other service conditions could cause the pipe to move out of the coupling.

Cam-Lock Joint Restraints

Smith-Blair Cam-Lock Joint Restraints save labor by providing superior restraint with fewer wedges and install on IPS size PVC without modifications. The Cam-Lock's lower bolt torque and wider wedges reduce pipe stress. Cam-Lock Features include color-coded nuts and wedges, epoxy coating, visible wedge engagement and longer T-bolts. Available in sizes 3" through 24".

Bell-Lock Joint Restraints

Smith-Blair Bell-Lock Joint Restraints provide a quick and efficient means of restraining hydrants, valves, pipe bells and fittings used in water and wastewater systems.  Bell-Lock features include recessed shoulders for single wrench installation, compatible with standard MJ and some push-on style fittings. Available in sizes 4" through 12". 

Anchor Studs

Smith-Blair Anchor Studs are designed as an alternative coupling method to harness assemblies for applications where moderate longitudinal stresses are encountered.

EZ-W Restraint Couplings

Smith-Blair EZ-W Restraint Couplings for water service are designed with push on gaskets and engineered to simplify installation, restrain the pipe joint and ensure a tight seal. EZ-W Couplings can be used to connect IPS PE to steel pipes 1" through 12" diameters and ductile iron to IPS PE, PVC or steel pipe, 2"-8".
