Parker’s KB163-90 is a 90 Shore A black HNBR compound engineered for high-temperature hydraulic and oilfield sealing applications where strength, extrusion resistance, and rapid gas decompression (RGD) performance are critical. Designed for demanding service, it operates reliably across a service temperature range of approximately -25°F to 300°F, with short-term capability up to 325°F, while maintaining mechanical stability under pressure. The hydrogenated nitrile formulation delivers excellent resistance to petroleum-based hydraulic oils, motor oils, transmission fluids, greases, R134a refrigerant, water and glycol mixtures, steam, and HFA, HFB, and HFC hydraulic fluids. Its resistance to ozone, aging, and weathering supports long service life in harsh industrial and outdoor environments.
KB163-90 is qualified for RGD service and meets NORSOK M-710 requirements, making it well suited for oil and gas applications involving pressure cycling and aggressive service conditions. It is commonly used in oilfield hydraulics, valves, pumps, and pressure-containing components where high durometer and extrusion resistance are required. The compound is not recommended for polar solvents such as ketones and esters, strong acids, chlorinated hydrocarbons, or automotive and aircraft brake fluids. Canyon Components offers equivalent HNBR materials designed to match the high-temperature, hydraulic fluid compatibility, and RGD performance of Parker KB163-90 for severe service sealing applications.
