HNBR-HYDROGENATED NITRILE RUBBER

HNBR is a highly saturated elastomer produced by special hydrogenation of nitrile butadiene rubber (NBR). Since its creation in the 1930's, the petroleum-based synthetic rubber, NBR has long been the standard for general purpose, low cost and low heat applications while FKM (fluorcarbon)has been the choice for higher heat. more...

CUSTOM MACHINED SEALS

Custom machined seals are a great sealing option when product isn't available, cylinders have been modified, or when prototypes are needed, (without the expense and leadtime of tooling). There hundreds of profiles and materials available, made on demand with some lead times as quick as the next day.more...
