Drive the Hydrogen Economy

Electrolysers and Fuel Cells

Greene Tweed solutions for fuel cells are built to handle material outgassing, chemical compatibility, and wear in extreme environments: 

Arlon® 3000XT

  • Improved chemical resistance over standard PEEK
  • Retaining mechanical properties of standard PEEK at higher temperature
  • Permeability 200X lower than standard PEEK

Chemraz®

  • Exceptional chemical compatibility
  • Low outgassing properties
  • High temperature capabilities up to +300°C

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. 

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. 

Versatile Sealing and Scraping for Demanding Environments 

MSE® metal spring energized seals are custom designed with a dual-lip body for superior performance in the most demanding 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)

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.
