Threaded O-ring Plugs - NPT Threads

In stock

Threaded O-ring Plugs for NPT Threads include a compressed flange lip and an O-ring 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 also absorb paint, which keeps paint flaking to a minimum.

It may be installed by hand or with a 12-point socket head, screwdriver or wrench. This threaded plug is suggested for usage where strength and abrasion resistance are required since it can tolerate temperatures ranging from -40F to 230F | -40C to 110C. Used in industries such as oil and gas, plumbing, and automotive where leak-proof seals are critical to system integrity.

  • Material: Nylon, HDPE
  • Colour: Natural, Black
