Overmolded plate seals
Elastomer seals (FKM, silicone, fluorinated silicone) can be overmolded within grooves on anodized aluminum or nickel-plated supports. This enables perfect positioning between elements to be sealed, independently of the orientation and accessibility of the seal.
Features & Benefits
- Simple, visually & verifiable installation (correct location of the rubber part in front of the sealing surface)
- High-pressure performance (more than 200 bars as well as vacuum)
- Easy maintenance even in a vertical position with very low space between flanges
- Multi-port sealing with one component
- Ability to seal complex flange geometry.
- Solid metal-to-metal contact insures stable joint with no re-torque required
- Redundant seals can be incorporated into one component
- No machined grooves required in mating flanges
- Different rubber and materials (and coatings) retainers: FKM, Silicone and Fluorosilicone seal materials
- Specific design features (metal-to-metal design, special seal profile) contribute to safe static sealing of aircraft fuel systems
- Can also be used in dynamic applications (relief valve, poppet valve)
Product Applications
Aircraft engines:
- Sealing on compressors, pumps & gearbox assemblies
- Sealing on flanges and connections of air, oil & fuel management systems
- High sealing pressure on Kerosene post combustion’s hydraulic device
Hydrogen production:
- Sealing on separation stacks
Nuclear:
- Sealing on primary pumps filters
