API 682 Seals

The Stein Seal Company has developed API (American Petroleum Institute) 682 seals for the oil and gas industry market. Stein Seal has designed, manufactured and tested a Type A pusher seal, Arrangement 3, dual pressurized cartridge seal for this market. In an Arrangement 3 design the barrier fluid pressure is kept higher than the seal chamber pressure and is designed to handle and contain hazardous and light hydrocarbon fluids. The process-end face (inner) seal is specially balanced to handle reverse pressures while the atmospheric-end (outer) seal will contain the barrier fluids.

The Stein Seal Type A pusher seal is also available in Arrangement 1 and 2. An Arrangement 1 seal is a single contacting wet cartridge seal with a bushing. Arrangement 2 cartridge seal is the same configuration as the Arrangement 3 seal but is an un-pressurized dual seal where the barrier fluid pressure is kept lower than the seal chamber fluid pressure. The atmospheric-end (outer) seal will provide additional containment of hazardous fluids.

The Stein Seal Company seals designed for the oil and gas industry are built and qualification tested according to the rigorous API 682 standard’s test protocols.
