Pressure Compensators

Designed to balance the internal pressure of oil filled subsea equipment and hydraulic systems with the ambient pressure of the surrounding sea water, Tecnadyne’s  pressure compensators have been proven in the world’s harshest subsea environments for many years. The PCX pressure compensators are compatible with all common hydraulic oils and are rated for operation to full ocean depth.
