Threaded O-ring Plugs - NPT Threads

In stock

Threaded O-Ring plugs for NPT threads are used to protect NPT threaded fittings. The O-Ring gives this part a watertight seal for superior leak protection. Unique head design allows the user to apply or remove this plug by hand or with a 12-point socket head, screwdriver or wrench. Parts come in HDPE for everyday applications or in nylon, which is recommended when abrasion or heat are involved.
