National Pipe Thread (NPT) Plugs

Plugs for NPT threads

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

Choose from standard NPT plugs – both threaded and non-threaded styles – to protect piping used in plumbing, hydraulic and other connections. Our TH, TPN and TPN-F series are ideal for low-pressure testing and in-plant processing, with the latter designs featuring a square head for use with standard wrenches. Other designs include push-in plugs and knurled plugs that can easily be inserted by hand and quickly removed with options like the pull-tab design found with the PIP-TAB series.
