This GF Piping Systems schedule 40 PVC coupling has socket openings on both ends and is suitable for connecting two unthreaded pipes with the same diameter going in the same direction to extend a straight run. The socket ends connect to pipes with a smooth bore for enhanced flow. This coupling is made of white PVC (polyvinyl chloride) for chemical and corrosion resistance, high strength, and less weight than fittings made from metal. It is compatible with schedule 40 PVC pipes and fittings and is suitable for cold-water pressure distribution systems including irrigation, pool and spa, potable water, and chilled water applications. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. The fitting has an operating temperature range of 0 to 60 degrees C (32 to 140 degrees F), meets ASTM International D1784, D1785, and D2665 standards for quality assurance, and meets National Sanitation Foundation International (NSF) standards 14 and 61 for potable water service. This schedule 40 PVC coupling is suitable for connecting pipes for conveying drinking water, waste water, chemicals, and other liquids in a range of industries.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe 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).
