Custom Seal Rings & Piston Rings for Challenging Applications divider

United Ring & Seal, Inc. is a precision manufacturer of metal seal rings and piston rings used in high temperature and hostile, challenging operating environments. Applications include stationary gas turbines, jet engines, pump equipment, fluid ducting, specialized internal combustion engines, high temperature and high pressure valves, hydraulic and compressor applications.

We manufacture from all cobalt, nickel, chrome and iron based alloys used in high temperature hostile environments as well as cast iron, bronze and aluminum-bronze alloys. Expanding and contracting rings with various cross-sections and with all end joints are manufactured. Our rings are used as fluid seals in combustion and cryogenic service, oil seals for bearings, gas and liquid seals for valves, nozzles, hydraulics and ducting as well as compression seals and oil control seals. They are used anywhere there is a need to seal gases or liquids in rotating, reciprocating, jointed or stationary service.
