Hydrogenated Nitrile Butadiene Rubber (HNBR) is resistant to abrasion and retains properties when exposed to heat, oil, gas or steam. In some situations, HNBR rubber can withstand up to 140°C temperatures for a short period of time.
Yellow HNBR rubber is used for seals on press fit fittings to suit gas systems. It is suitable for temperatures between -20°C and +70°C, and for pressures up to a maximum of 70PSI / 5Bar.
