Product Description

The NIBCO 4803-2 adapter pipe fitting is made of PVC for drain, waste, and vent systems (DWV) and has a spigot connection and a female National Pipe Taper (NPT) threaded connection. This adapter fitting connects pipes or fittings with different end types, diameters, or materials. It has a male spigot connection on one end for fitting into a female unthreaded pipe and female NPT threads on the other end for connecting to a male threaded pipe. The NPT threads create a tighter seal than straight threads, and the spigot end has the same diameter as the pipe it connects to, minimizing turbulence and creating a tight seal. This fitting is made of PVC for use in non-pressure residential and commercial drain, waste, and vent (DWV) sanitary systems. PVC resists corrosion and chemicals, exhibits high strength, and weighs less than fittings made from metal. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. This fitting provides superior flow to metal because of its smooth interior finish, which reduces friction and inhibits buildup of materials. This fitting meets American Society for Testing and Materials (ASTM) D2665 and D3311 specifications for quality assurance.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).NIBCO manufactures flow-control products for construction, industrial, fire protection, and irrigation applications. The company, founded in 1904, is headquartered in Elkhart, IN, and meets International Organization for Standardization (ISO) 9001 standards for quality assurance.
