Other Stainless Steel pipe fittings casting, such as stainless steel elbow, stainless steel tee, union, socket and stainless steel coupling.
Quick coupling used to connect two ends of two different pipes together in a fluid tight manner. It is designed for convenience in installation, high strength, compact size, easy manufacture with a low production cost, high efficiency and does not require the use of special tools for installation. The coupling utilizes a grab ring module that has a grab ring made with embedded stainless steel, thereby strengthening the fixing force and allowing for quick installation. A flaring surface on a retaining flange has an angle that corresponds to a tapering surface of the grab ring module. When the flaring surface and the tapering surface contact each other, the grab ring module compresses the surface of the pipe. Because the grab ring module has an outer plastic body with a small inner part, the grab ring module can be compressed to the pipe without causing fatigue of any members inside of the fitting. A specialized tool allows for quick and easy dismantling of the fitting.
