Energy: Carbon-Free: Metal Seals Applications
Description
Omniseal® Metal Spring-Energized Seals are enabling the transition to carbon-free energy, providing critical sealing performance in the most demanding hydrogen applications. Specifically engineered for H2 compliance, our seals deliver reliability and leak-tightness in liquid hydrogen (LH2) pumps, valves, and couplings, ensuring safety and efficiency in the entire hydrogen value chain.
H2 Compliant, Spring-Energized Seals for LH2 Pumps, Valves, & Couplings

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)
