This fitting is made of acetal copolymer plastic, which has low moisture absorption, high tensile and flexural strength, and is hard and fatigue resistant. It is suitable for soft metal, plastic tubes, air, or inert gases. This fitting meetings National Sanitation Foundation (NSF) standards 14, 51, and 61 for plastic piping systems, food equipment materials, and use with drinking (potable) water.

Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Quick connect tube fittings allow flexible tubing to be quickly and safely connected and disconnected, reducing spills and increasing safety. When purchasing fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
