This PT Coupling PTCN series combination nipple hose fitting is made of polypropylene plastic (PP) and connects hose to threaded pipe conforming to the National Pipe Thread (NPT) standard for low-pressure discharge or suction service. This adapter has a barbed fitting on one end that creates a tight seal on flexible or semi-rigid hose when used with a hose clamp or crimp sleeve or ferrule (sold separately), and a male NPT connector on the other end connects to threaded pipe. PP resists most chemicals, and is resistant to abrasion and corrosion.

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).

PT Coupling manufactures pneumatic and hydraulic hose fittings for industrial and automotive applications. The company, founded in 1951 and headquartered in Enid, OK, meets International Organization for Standardization (ISO) standard 9001.
