Omniseal® Metal Spring-Energized Face Seals

Metal-O-Ring-Face-Seal
Omniseal®
Metal O-Rings

These metal face seals are long lasting seals and unlike non-metallic seals, they are not subject to failure due to incompatibility with the environment, outgassing, or deterioration from age.

Since O-Ring seals are used as static face type seals, they should not be used as a dynamic seal. While the majority of seals are circular, these seals can also be produced in rectangular, racetrack, and other various shapes and configurations. Metal O-rings are typically used in hot mold equipment, nuclear reactor vessels and gas turbines.

Seal Function & Motion

Metal-O-Ring-Profile

Adaptability

Metal O-Rings can be vented, gas filled, pressurized or spring-energized for specific conditions such as a higher pressure, higher temperatures and extremely high pressure.
