Stop-Lok Adapter, 1-1/2" FPT

OPW Stop-Lok™ Multi-application Couplers are engineered for high heat, high pressure, and demanding liquid transfer applications. Offering a more secure connection than traditional Kamvalok® camlock couplers, Stop-Lok™ couplers feature an innovative tool-free locking design and cannot be overtightened; simply hand tighten the scalloped collar, and "when it stops, it's locked." The tightening sleeve protects dual O-ring seals that offer enhanced leak protection and helps prevent thread galling. A smooth-bore design ensures optimal, unrestricted flow through the entire fitting without any variation in pipe diameter. Stop-Lok™ couplers are made of 316 stainless steel and engineered to operate up to 400 PSI and temperatures from -20° F to 400° F depending on the seal type*.
