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)

Case Studies
Metal Boss Seals For Fuel & Hydraulic AS5202 Fittings
In space applications, standard fittings are specifically used to tackle several high-end connections and extreme conditions for fuel and hydraulic ports. In particular, AS5202 ports and fittings are installed in not only spacecraft and aircraft but are also valued in nuclear and industrial applications.
High Pressure Turbine Shrouds
A high pressure turbine in a jet engine is one of the hottest parts in an airplane since this section is right after the combustion section and can reach extreme temperatures and pressures from the expanding airflow. Maintaining air flow control in this area is key to ensuring the efficiency of the engine because any type of leak is a waste of energy. To maintain a tight control on air flow in the turbine as well as limit vibration, metal shrouds are used, facing the tip of the turbine blades.
