Take On Extreme Conditions
Hydrogen Valves
Greene Tweed understands it is necessary to keep fugitive emissions low to stay safe when working with hydrogen – that’s why our solutions are built from the strongest materials for secure hydrogen processing:
Stem seals
- Avalon® 56 V-stacks made from low permeability, high purity modified PTFE that can reduce leakage at low temperature (-40°C / -40°F) and high pressure (700 bar / 10,152 psi)
RGD resistant seals
- Fusion® 938 O-rings made from high performance FKM with exceptional resistance to H2 exposure
- MSE® spring energized lip seals for extreme temperatures (from cryogenic to 288°C / 550°F) and pressures (up to 2 070 bar / 30,000 psi)
Low temperature seals
- Fusion® 665 O-rings made from high performance FKM for low temperature services (-57°C / -71°F)

Industry-Proven Products
When Downtime isn’t an Option
The most common type of elastomer seal, Greene Tweed’s O-rings provide cost-effective, flexible sealing solutions for industry’s harshest conditions. The O-ring can be used either as a seal itself or as the energizing element in PTFE, cap-type seals.
For additional backup rings, Greene Tweed’s engineers will work with you to develop a custom configuration suited to your needs.
