As hydrogen and LNG gain momentum as clean fuels, conventional sealing systems face unprecedented challenges. Preventing methane or hydrogen leakage is not only vital for environmental protection but also a key safety requirement when handling flammable gases.

Fluorten has developed a patented cryogenic seal designed to ensure leak-free performance in extreme conditions—from -269 °C to +280 °C. Its modular construction combines radial and frontal sealing elements, offering a double barrier against leakage and maintaining sealing integrity even with temperature-induced dimensional changes.

Key Benefits

• Zero leakage (proven in helium tests, 10x better than standard seals)

• No shrinkage: sealing remains effective despite diameter changes

• Enhanced safety and emission control

• Excellent performance under cryogenic cycling

Materials

• Victrex CT™ 200 (Cryo-PEEK)

• PCTFE, modified PTFE

• Low-porosity polymers

Applications
Hydrogen, LNG, and other cryogenic media.
