National Pipe Thread (NPT) Plugs

Plugs for NPT threads

National pipe thread (NPT) plugs are designed to fit many standard threaded pipes. Whether you need to protect piping during finishing processes, transport, storage or installation in the field, Caplugs has a solution to fit your needs.

Choose from standard NPT plugs – both threaded and non-threaded styles – to protect piping used in hydraulics, plumbing and more from moisture, dirt and other potentially dangerous contaminants.

Our national pipe thread plugs are ideal for protecting internal threads during low-pressure testing and in-plant processing, with several featuring a square head for use with standard wrenches. Our push-in plugs and push-in plugs with pull tabs offer easy installation and removal to save time during finishing operations like wet painting.
