The Gruvlok Fig. 70 SlideFLEX flexible coupling from ASC Engineered Solutions is designed for installations in mechanical systems with an operating pressure up to 1,000 psi. The lightweight coupling can be used with linear and angular defection, and allows for fast, low-cost installation on roll or cut grooved steel pipe and Gruvlok grooved-end fittings and valves. The coupling’s patented SlideLOK gaskets in two to eight-in. sizes provide four separate sealing surfaces for added protection.
