1-inch Sch. 40 PVC Union

This union pipe fitting with an O-ring is made of schedule 40 PVC and has female threaded end connections. This union fitting has three pieces and includes a threaded connection that can be screwed or unscrewed to connect or disconnect pipes more easily than with a coupling. 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.

Schedule 40 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 40 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 paraffinic 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
