Hose arrangement having a rubber hose on a connecting piece

摘要

A hose arrangement consists of a connecting piece having a nipple and having a rubber hose whose one end is pushed onto the outer surface of the nipple. A layer which is produced mainly from hydrogenated nitrile rubber is located between the outer surface of the nipple and the inner surface of the rubber hose. The hydrogenated nitrile rubber having a smaller quantity of unsaturated double bonds than nitrile rubber has a better oil resistance and a higher oxidation resistance. The layer produces a good seal in the clamping region if the rubber hose is produced from nitrile rubber.
