Metal C-Rings
C-rings are medium to high load seals for axial compression with a medium spring back.
In case a medium to high leak tightness as well as flexibility of the seal are required, C-rings can be used.
C-rings are available for internal and external pressure and are also available as shaped seals.
Typical applications
- Aerospace (GT, fuel systems, hydraulic, satellite, propulsions)
- Oil and gas & power generation
- GT, ST-casing, injections systems, heat exchangers
- Nuclear waste (cask seals)
- Equivalent for boss-seals
- Valves
- High end industrial applications
- Valves
- Cryocoolers
- Turbo chargers
- Exhaust
- Lasers
- Vacuum application
- Double sealing solutions
- Remote handling
- Hot mold

Features / requirements
Benefits
Low to moderate sealing load
Suitable for softer flange materials (Al,…)
Lower bolt force required
Increased spring back
Allows flange lift off
Narrow sealing surface, (line contact)
Moderate seating stress
High sealing capability at low compression force
Pressure activated
Critical circular surface finish required
