SlideLOK's unique design allows for fast, easy and safe installation. The installer simply lubricates the exposed gasket surfaces and slides the coupling completely over the pipe end, where it securely remains until the installer adds the adjacent component and slides the coupling into place. An impact or socket wrench tightens the two bolts to finish the job. SlideLOK features a patented coupling and pressure-responsive gasket with four separate sealing contacts that engage the groove 360 degrees around the pipe. A specially developed leading edge eliminates gasket pinching, and the gasket lips facilitate easy slide-over action. The pressure-responsive gasket uses technology unique to the industry and only available with the SlideLOK couplings.
