The REHAU EVERLOC compression-sleeve fitting system has 26 additional configurations, making transitions between pipe sizes more convenient in plumbing and hydronic piping, REHAU notes. The system comprises RAUPEX PEXa pipe in 3/8” to 2” diameters, polymer and lead-free brass fittings and power tools for reliable, safe and cost-competitive connections, the company adds. Designed for no-leak security, the two-step fitting expansion and compression process is performed quickly in any weather, making installation faster than copper and other PEXa cold-expansion fittings, REHAU states. The NSF/ANSI 14&61-certified system delivers safe drinking water with no mineral build-up and is backed by a 25-year limited warranty.
