Metal O-Rings are used as static face type seals and should not be used as a dynamic seal. While the majority of seals are circular, many seals are produced in rectangular, racetrack, and other various shapes and configurations with limitations only on the corner radii.
The following are key elements in specifying the proper seal determining the base material:
- Temperature limits/duration
- Media to be sealed
- System pressure
- Available seating load
Plating and Coatings:
Plating or Coating of the O-Ring Seal provides a soft malleable surface that will smear into small imperfections in the mating hardware, enhancing seal performance.
Metallic O-ring Seals can be produced in various shapes.
The typical application places a Metallic O-Ring Seal in an axial compression between two parallel surfaces, which are square to the fluid passage or vessel axis. The seal is usually located in an open or closed groove in one of the surfaces. The seal can also be located in a retainer, which eliminates the need for machining a groove. The mating hardware when bolted, torque, clamped or fastened tightly to the surface enclosing the ring, compresses the seal, forming a positive joint
O-Seals are commonly used in the following industries:
- Oil and petrochemical industries
- Plastic molding
- Vacuum Processing/Research
- Diesel engines
