TR Flex Restrained Joint Ductile Iron Pipe is the most-widely accepted and installed integrally-cast restraint joint system in the ductile iron pipe industry. Proven as a versatile and easy-to-use item, this joint is flexible, sure, and watertight to and beyond its 350-psi pressure rating while preventing longitudinal separation of the joints whether installed above or below ground. TR Flex utilizes the Tyton joint gasket for a watertight seal along with a factory adapted spigot and extended bell casting to provide positive and permanent joint restraint.
