HNBR O-Rings & Seals
In comparison to NBR, HNBR O-Rings have increased chemical and weathering resistance. HNBR has excellent abrasion resistance, making it a viable alternative to Viton® FKM. HNBR also has better low temperature properties and tear resistance than fluorocarbon.
HNBR is used for a variety of products, including O-rings, packings, wellhead seals, drill bit seals, blowout preventors, and drill pipe protectors.
