Stop-Lok™ Multi-Application Coupler

For decades, union and ground-joint fittings have been used to quickly connect pipe and hose, which allows facilities to load and unload product more efficiently. OPW’s Stop-Lok™ Multi-Application Coupler builds on the compact structure and efficient functionality of traditional fittings and adds a few learned tricks.

Available in 3/4-, 1-, 1-1/2-, 2- and 3-inch sizes, Stop-Lok™ couplers are constructed of 316 stainless steel and have an operational temperature range of -20ºF to 400ºF (-29ºC to 204ºC).
