The Spears P105X series DWV cleanout adapter is made of PVC, has one spigot connecting end and one female NPT connecting end, includes a plug, and connects pipes or fittings of different types. It is suitable for waste water systems in residential applications. This fitting is made of PVC (polyvinyl chloride) for corrosion resistance, high strength, and less weight than fittings made from metal. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. This cleanout adapter fitting adds a cleanout port to an unthreaded pipe and comes with a plug to terminate the pipe and close the cleanout port, and it has an operating temperature range of 73 to 140 degrees F (23 to 60 C). The spigot connection fits into the end of a female unthreaded pipe for enhanced flow and the female National Pipe Taper (NPT) threaded end connects to male NPT-threaded pipes for a tighter seal than straight threads. This drain, waste, vent (DWV) adapter fitting complies with American Society for Testing and Materials International (ASTM) D2665 and ASTM D3311 for quality assurance, is National Sanitation Foundation International (NSF)/American National Standards Institute (ANSI) Standard 14 certified to the Uniform Plumbing Code (NSF – U.P. Code) and NSF-dwv for quality assurance, and conforms with lead content requirements for "lead free" plumbing as defined by California and Vermont. It is suitable for waste water systems in residential applications.

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).

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