Threaded O-ring Plugs - UNF Threads

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

Threaded Sealing Plugs - UNF Threads

These Threaded Sealing Plugs for UNF are designed with a double sealing ring on the underside of the flange to provide a secure and reliable seal. The nylon material absorbs paint, minimising paint flaking and protects from contaminants like dirt, dust, and debris, not trapping liquid and moisture from the hole.

It is easy to install and remove by hand, but its hex head allows the plug to be applied or removed with a spanner, Allen key or socket. Due to its material, it is capable of withstanding temperatures in the range of -40F to 320F | -40C to 160C. Used in various applications, including hydraulic, pneumatic and general engineering industries.
