461 Series PVC Pipe Fitting: 1/2 NPT Male x 1/2 Spigot Adapter

The Spears adapter pipe fitting is constructed of schedule 40 PVC and features a male NPT end connection and a spigot end connection. This fitting is designed to connect pipes or fittings with different end types. On one end, it has male National Pipe Taper (NPT) threads for connecting to female threaded pipe, and on the other end, it has a male spigot connection for fitting into a female unthreaded pipe. The NPT threads create a tight seal, while the spigot end matches the diameter of the pipe it connects to, minimizing turbulence and ensuring a secure seal.

Made of PVC, this schedule 40 fitting offers corrosion resistance, high strength, and is lighter in weight compared to metal fittings. It is compatible with schedule 40 PVC pipes and fittings, and can also be connected to materials such as steel, copper, or cast iron using transition fittings. Its smooth interior finish provides superior flow compared to metal fittings, reducing friction and inhibiting material buildup.

In terms of quality assurance, this fitting complies with NSF/ANSI 61 Annex G, NSF/ANSI 372, and meets lead content requirements for “lead free” plumbing, as defined by state laws and the U.S. Safe Drinking Water Act. It is suitable for use in cold-water pressure distribution systems, including irrigation, pool and spa, potable water, and chilled water applications.

Pipe fittings are crucial components used for connecting, terminating, controlling flow, and changing the direction of piping in various industries. When selecting pipe fittings, it is important to consider the application, as this will impact the material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in a wide variety of shapes, styles, sizes, and schedules.

Spears Manufacturing, founded in 1969 and headquartered in Sylmar, CA, produces thermoplastic fittings and valves for fluid, drain, waste, and vent systems. The company adheres to the International Organization for Standardization (ISO) standard 9001 for quality management.

In summary, the Spears adapter pipe fitting is an ideal solution for connecting pipes or fittings of different types, offering excellent corrosion resistance, strength, and a secure, tight seal. It meets stringent quality assurance standards and is suitable for a range of cold-water applications.
