PVC Pipe Fitting Adapter, Schedule 40, 1 NPT Female

The Spears 478 series adapter is a schedule 40 PVC fitting designed for connecting pipes or fittings with different end types. It features a female NPT connection and a spigot connection, and is suitable for use in waste water systems for residential applications. Made of PVC (polyvinyl chloride), this schedule 40 fitting offers corrosion resistance, high strength, and is lighter in weight than metal fittings. It can also be connected to other materials such as steel, copper, or cast iron using transition fittings.

This adapter fitting connects pipes or fittings running in the same direction using a female NPT connection and a spigot connection. The female NPT connection provides a tighter seal than straight threads when connecting to male NPT threaded connections, while the spigot end fits into the end of a female unthreaded pipe. With an operating temperature range of 73 to 140 degrees F (23 to 60C), this adapter fitting meets ASTM D2466 and ASTM D2609 for quality assurance, as well as NSF/ANSI Standard 61, Annex G for potable water. It also conforms with lead content requirements for "lead free" plumbing as defined by California and Vermont.

Pipe fittings are essential components used for connecting, terminating, controlling flow, and altering the direction of piping in various industries. When choosing pipe fittings, it’s important to consider the application, as this will impact the material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in different shapes, styles, sizes, and schedules (pipe wall thickness).
