Cryogenic valve seals, spare parts & service
WCS manufactures and supplies seals and wear parts for every major cryogenic valve brand on LNG and LPG carriers — including discontinued models the original manufacturer no longer supports.
Pick your valve or actuator below for seal types, sizes, photos and case studies, or send us your OEM quote and we'll beat it by at least 25%.
Reverse-engineered, remanufactured, in stock
Like our competitors, WCS outsources soft-seal production to an established plastics specialist. Unlike them, we manufacture our own metal seals in-house in Norway — and remain the only supplier for some discontinued valve types.
