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.

NewDealSeals supplies HNBR O-rings & seals in any dimension. Do you need sealing expertise and service around your applications? Call +31(0)226362233 or mail us
