Applications
Nuclear: Metal Seals Applications
Description
Omniseal® metal shaped seals and large diameter seals are used due to their ability to withstand heat without creating FOD in nuclear applications.
Shaped seal for vacuum chambers cyclotron, ion beams, pet scans
Large diameter metal spring-energized seals for Pressure Vessels and Heat Exchangers in SMRs

As required
Depending on the type of Metal Seal, the solution can be used for static and semi-dynamic face or axial sealing in extreme temperature, pressure, vacuum, and radiation environments.
Applications include:
- Low to moderate load with high spring back (C-Seal, V-Seal, E-Seal)
- Medium to high load with increased spring back and wider sealing surface (Spring-Energized C-Seal)
- Ultra-high vacuum and cryogenic sealing (Aluminium Spring-Energized Seal, O-Ring)
- Shaft and bore sealing in semi-dynamic, rotary, and reciprocating applications (Axial C-Seal, Lip Seal, Comma Seal)
- Non-circular and shaped geometries (Shaped Seal, Machined Seal)
- High spring back for large flange movement or thermal cycling (V-Seal, E-Seal)
- High seating stress for rough surface finishes or soft flange materials (Spring-Energized C-Seal, Aluminium Spring-Energized Seal)
- Long-term static sealing under radiation exposure (C-Seal, Spring-Energized C-Seal)
- Standard fitting interfaces (Boss Seal for AS5202, E-Seal for AS1895)
