The Double-See pressure-rated double-containment vinyl piping system from GF Piping Systems offers an easy installation method, a closure coupling design that allows conformance to the ASME B31.3 test inspection requirements, and 3-D thermal expansion compensation. Both primary and secondary pipes are cut to the same length and can be joined simultaneously, saving time and preventing potential mistakes caused by staggered pipe-cut measurement errors. It offers assembled and tested fittings and a pipe-cut length guidance system that simplifies installation. The system has pipe, fittings, leak detection and access tees, closure couplings and termination fittings. It is available in PVC and CPVC; either material may be primary or secondary, with clear PVC an option for the containment pipe. System size options range from 1/2- by 2-inch to 6- by 10-inch. 800/854-4090; www.gfpiping.com.
