Threaded O-ring Plugs - Metric Threads

In stock In production

Threaded O-ring Plugs for Metric 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 be installed using a spanner, screwdriver, or by hand. Metric threads are available. The fine taper of metric tapered thread allows for the best possible force transmission. Used in oil and gas, plumbing, and automotive sectors where leak-proof seals are crucial to system integrity.

  • Material: HDPE, Nylon
  • Colour: Yellow, Orange

Threaded O-ring Plugs - NPT Threads

In stock In production

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

Threaded O-ring Plugs - UNF Threads

In stock In production

Threaded O-ring Plugs for UNF 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. Often used on flat-faced hydraulic fittings, it is recommended when strength and resistance are desired as it can withstand temperatures that range from -40F to 230F | -40C to 110C. Used in oil and gas, plumbing, and automotive sectors where leak-proof seals are crucial to system integrity.

  • Material: PP, LDPE, HDPE, Nylon
  • Colour: Yellow, Red, Natural
  • Material Flammability Standard: UL94 V-0
