UNF Sealing Plugs

Our UNF Threaded Sealing Plugs are manufactured from a High Density Plastic (HDPE) and paired with a Nitrile Rubber O-Ring which provides the sealing properties. The use of a Rubber O-Ring allows for a tight seal which is able to prevent liquids or gases from flowing through an application, hence their popularity within Engineering based Oil, Gas and Hydraulic industries. UNF Threaded Sealing Plugs are as the name suggests, compatible with UNF (Unified) threads which generally differ from their Metric or BSP equivalents by pitch or coarseness of thread.

We stock UNF Threaded Sealing Plugs in a wide range of different Head Sizes and Unified Threads 3/8" x 24 to 1 7/8" x 12 which ensures we have the perfect product for you. If you require a custom size or variant not displayed below then please get in touch with a member of our team.
