AS568-232 O-Ring for Oilfield Pumps, Valves and Pressure-Control Equipment
Royal Way AS568-232 O-rings are a standard-size sealing option for oilfield pump, valve, hydraulic-cylinder and pressure-control equipment. The 2.734 in ID and 0.139 in cross section are paired with NBR, HNBR or FKM compounds in 70 or 90 Shore A options, giving maintenance and equipment teams a clear size-and-material reference for replacement and production programs. Jiangsu Ruowei manufactures oilfield rubber seals at its Haimen facility in Nantong, Jiangsu, with coordinated mixing, molding, vulcanization, inspection and packing.
