Solutions for When
it Can’t Fail
As constant innovators, Greene Tweed stays ahead of the game when it comes to securing the future of the hydrogen economy. Our experts develop clean, safe, and reliable products for applications that are too important to fail.
HYDROGEN VALVES
Take On Extreme Conditions
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:- 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)>
- Fusion® 938 O-rings made from high performance FKM with exceptional resistance to H2 exposure
- GT® Ring for extreme pressures (up to 900 bar / 13,050 psi) and RGD resistance
- 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)
- Fusion® 665 O-rings made from high performance FKM for low temperature services (-57°C / -71°F)
- Arlon® 3000XT cross-linked PEEK with exceptional creep resistance (25x better than PEEK)

ELECTROLYSERS AND FUEL CELLS
Drive the Hydrogen Economy
Greene Tweed solutions have been designed to handle the increase in temperatures and pressures required to develop the next generation of fuel cells and electrolysers Arlon® 3000XT:- Improved chemical resistance over standard PEEK
- Retaining mechanical properties of standard PEEK at higher temperature
- Better resistance to thermal cycling
- Available as structural rings, cell frames for electrolysers, and compression end plates or MEA sub-gasket films for fuel cells
Fusion® 665 O-rings made from high performance FKM for low temperature services (-57°C / -71°F)
O-RINGS AND BACK-UP RINGS
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.
T-SEALS
Advanced T-Seals for Demanding Applications
Greene Tweed offers a wide range of standard and custom engineered T-seals for easier assembly, low leakage, and longer service life.
METAL SPRING ENERGIZED (MSE®) SEALS
Versatile Sealing for Demanding Environments
When equipment failure is not an option, Greene Tweed MSE® metal spring energized seals provide superior sealing in even the most volatile conditions:- High pressure or low pressure requirements, from vacuum up to 30,000 psi (2,070 bar) plus
- Large temperature variation, cryogenic to 550°F (288°C)
- Critical friction requirements
- Critical wear and life requirements
V-Rings
Versatile Sealing and Scraping for Demanding Environments
For applications requiring specialized elastomeric and/or thermoplastic properties, Greene Tweed’s V-rings, adapters, and seal stacks deliver proven performance when exposed to extreme temperatures, corrosive chemicals, and other damaging contaminants.
