A metal seal is distinct due to its material. For axial seals, the design is determined by what strength and temperature properties are needed; most times, they will be produced from high temperature super alloys like Inconel® material.
Since our business has a large range of metal materials available, you will receive a metal solution that fits your needs.
While the inner design of a metal seal is key, the outside is just as important. Metal seal platings and coatings have exceptional features in sealing technology.
- The additional soft layer is instrumental in improving the leakage rate, used to fill the roughness of the counter flange and enhance the sealing performance.
- The softer the plating, the more it can improve and cover surface irregularities in the hardware. Generally, a metal seal lies side by side with the high demands placed on the surface quality of the customer’s hardware.
- Special patented coatings are used to improve the wear resistance. PTFE is typically applied, while plated seals use gold, silver, copper, tin, and nickel as a top layer. For jacketed seals, aluminum lining is used.
Since metal seals are engineered to address critical pressure, temperature and leak rate challenges, they have a greater design flexibility. As a result, our team has designed and manufactured special shapes to accommodate typical dimensional tolerances.

Proven Examples
Omniseal®
Metal Comma Seals
Comma axial seals used for shaft sealing and bore sealing are a further development of the axial C-Seal. The elastic recovery in radial direction is still limited, yet the leakage over the outer diameter in the case of a Comma seal is well controlled by the seating load generated by the compression of the ring part of the design.

Omniseal®
Metal C-Seals Axial
Metal face C-Seals help overcome both heat and pressure pulsating sealing challenges. The key to the seal's superior performance is the high springback characteristic due to the C-shaped construction. These highly resilient seals can be used for internal, external, and axial pressures under extreme conditions that preclude the use of gaskets made of organic materials.
Used in
where very low leak rates are demanded
Omniseal®
Metal Lip Seals
The metal axial lip seal is a patented design for use in high and low pressure as well as high and low temperature dynamic applications. This sealing solution provides excellent performance in thermal expansion applications or limited rotational or reciprocating applications.
