Four Commercial Lines: Engineered for years of continuous use

McGuire offers four lines of commercial grade stop valves, all designed, engineered and manufactured for years of commercial continuous use. The compression nuts are precision machined from high-copper content brass bar stock. The thickness of the sides and top of the nuts are specially designed to virtually eliminate cracking during installation (requires professional commercial installation and maintenance.) Equally important are the peroxide cured ethylene propylene dien monomer (EPDM) washers often referred to as the “purple washers” that will not degrade when exposed to chlorine, chloramines and high water temperatures.
