Threaded O-ring Plugs - NS-NF Threads

In stock

Threaded O-ring Plugs for NS and NF Threads include a compressed flange lip and an O-ring (optional) to provide a watertight seal and superior leakage prevention for hydraulic threads. The threaded O-ring keeps contaminants like dirt, dust, debris, and moisture out of the hole.

It may be installed using a hex wrench, screwdriver, or hand. Fits standard NS (National Special) and NF (National Fine) Class 1-2-3 threads. Used in oil and gas, plumbing, and automotive sectors where leak-proof seals are crucial to system integrity.
