74FP SlideLOK® Coupling
The patented 74FP SlideLOK coupling is the most rigid ready-for-installation coupling on the market. A unique slide action eases assembly and reduces installation time - even the last coupling can be installed without separating pipe ends. The patented 4Seal Pressure Responsive Gasket eliminates pinching and provides four separate sealing surfaces for added protection. Designed for use with roll, cut, or swage grooved steel pipe, Gruvlok® and SPF® grooved-end fittings and valves.
