HNBR O-Rings

HNBR O-rings are high-performance sealing components engineered for demanding industrial applications requiring superior resistance to heat, pressure, oils, fuels and mechanical wear. Hydrogenated nitrile rubber combines the excellent oil resistance of standard NBR with improved thermal stability, chemical resistance and durability, making HNBR seals ideal for harsh operating conditions.

APSOparts offers industrial HNBR O-rings widely used in automotive systems, oil and gas installations, refrigeration technology, hydraulic equipment, compressors, pumps and industrial machinery. These sealing solutions are especially suitable for applications exposed to high pressures, ozone, aggressive lubricants and temperature fluctuations. HNBR O-rings are commonly applied in engines, air conditioning systems, fluid handling equipment and industrial automation environments where long service life and operational reliability are critical. Their excellent abrasion resistance and mechanical strength make them a preferred sealing solution for OEM manufacturing, maintenance operations and heavy-duty industrial systems across multiple industries.

HNBR seals are used for applications that require resistance to high temperatures, chemicals and ozone. The material is resistant to ageing, durable and has good resistance to a wide range of oils, greases, acids and alkalis.
