OPW 2″ Double-Wall Swivel Pipe Coupling

Double-wall swivel couplings eliminate the need for cutting back the secondary jacket and rubber test boots. They have an integral interstitial access port for connector and test tubes. These double-wall couplings permit higher interstitial testing pressures and eliminate added parts and labor costs.

Double-wall pipe couplings require the use of an OPW Retail Fueling coupling machine to internally expand the stainless steel fitting onto the end of a FlexWorks pipe section. Internally expanded couplings have a long, successful history of reliable performance.
