The patent relates to a pressure compensator includes two reciprocally displacable sealing assemblies of allowing the exchange of fluid to permit overpressure compensation as well as underpressure compensation. In either case, rigid annular mating sealing surfaces cooperate to bear the brunt of the sealing load while either one of two resilient annular four-lobed seals bear against a continuation of the opposed rigid sealing surface to effect the primary sealing. Having the serially arranged heavy-duty rigid sealing surfaces and the resilient four-lobed seal renders the pressure compensator well suited for pressure regulation of gases and permits its interconnection to a source of high-pressure gas without the danger of failure.
