The Twister, LQC is the next generation of quick couplings designed to replace conventional Cam and Groove couplings that are used in critical service applications. The LQC is engineered to be used in conjunction with hoses and loading arms and has a built in pressure locking safety feature. The coupling will lock up during uncoupling should there be residual pressure in the line, and the ¼ twist rapid engagement makes it user friendly. The LQC is built to B31.3 specifications and ISO 9001-2000 quality standards and has pressure ratings equivalent to ANSI 150/300.
