TR Flex® Restrained Joint Pipe

The TR Flex® is the most widely accepted and installed integrally cast restraint joint system in the Ductile iron pipe industry. This easy-to-use product has proven versatility. It’s flexible, reliable, and watertight up to and beyond its 350-psi pressure rating. It prevents longitudinal separation of the joints, whether installed above or below ground. The TR Flex® utilizes the Tyton Joint gasket for a watertight seal, a factory-adapted spigot, and extended bell casting to provide positive and permanent joint restraint.
