This coupling pipe fitting, in gray, is made of schedule 80 PVC and has female threaded connections. This coupling fitting connects two pipes with the same diameter going in the same direction to extend a straight run. It has female National Pipe Taper (NPT) threads for connecting to male threaded pipes, creating a tighter seal than straight threads. This schedule 40 (standard wall) fitting is made of PVC (polyvinyl chloride) for corrosion resistance, high strength, and less weight than fittings made from metal. It is compatible with schedule 40 PVC pipes and fittings. Pipe dimensions for elbows are represented as "connection one" x "connection two" displaying either the same or reducing sizes.
Schedule 80 PVC pipes and fittings are suitable for cold-water pressure distribution systems including irrigation, pool and spa, and potable water systems. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. All PVC schedule 80 fittings service temperatures up to 140¬∞F (60¬∞C) allowing a wide range of process applications. All PVC fittings meeting ASTM International D1784 and D2466 standards for quality assurance, and is certified by National Sanitation Foundation International (NSF) for potable water service.
Unlike metal, PVC fittings never rust, scale, or pit and will provide many years of maintenance-free service and extended system life. PVC fittings are used for connecting, terminating, controlling flow, and changing the direction of piping in irrigation and drainage. PVC is generally inert to most mineral acids, bases, salts and parafinic hydrocarbon solutions. 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, and sizes
