Product Description

Buna-N o-rings also referred to as NBR o-rings and Nitrile o-rings are the most widely used o-ring material in the word because of low cost, good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, and the default choice for basic applications. Buna-N o-rings are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, keytones and many others.

Softer than standard Buna-N O-rings for a better seal in low-pressure applications, these are also resilient and offer excellent tear resistance. They resist hydraulic oils and motor oil. These O-rings have a round profile and are suitable for a wide range of static and dynamic sealing applications.

Common Industry Applications:

  • Oil and Gas Seals 
  • Explosive Decompression Resistant O-rings (Norsok M-710 Seals, NACE TM0297 Seals) 
  • Automotive Fuel and Oil Seals 
  • Military Applications (MIL Spec Compliant Seals)
