O-Ring Materials, Applications, and Selection

Summary Introduction An o-ring is an elastomeric ring with a round cross-section that forms a seal by squeezing and applying pressure. That sealing mechanism depends on the elastomer returning toward its original shape after deformation (elastic recovery) and maintaining contact pressure against the gland surfaces over time. Because elastomers respond differently to heat, cold, fluids, […]

HNBR’s Role in Advanced Sealing

Summary Introduction In the dynamic and ever-evolving world of industrial applications, the quest for materials that combine durability, resilience, and versatility has led to significant scientific advancements. One such breakthrough is the development of Hydrogenated Nitrile Butadiene Rubber (HNBR), a material that has revolutionized how industries approach sealing and longevity in harsh environments. This blog […]

HNBR Supply Chain Tightening

Global availability of HNBR, and subsequently HNBR o-rings, has been greatly challenged throughout 2021 due to the closure of a major production facility, which stopped production in the wake of a natural disaster. This, coupled with significant demand growth, is further tightening the market for this synthetic rubber. The global market for HNBR is primarily […]

HNBR O-Ring Expansion

Our customers are seeing an increasing demand for HNBR o-rings, especially in cold weather climates. To accommodate this demand, we have expanded our inventory of 80 durometer HNBR o-rings. HNBR o-rings have a broad temperature range (-40ºF to +302ºF), superior chemical resistance, and are often used in the oil & gas and automotive industries. For […]
