Industry-Proven Products

Simple, Versatile Sealing Solutions

The most common type of elastomer seal, o-rings provide cost-effective, flexible sealing solutions across a wide range of demanding applications. The o-ring can be used either as a seal itself or as the energizing element in PTFE, cap-type seals.

Advanced T-Seals for Demanding Applications

If you need a sealing solution with easy assembly, low leakage, and longer service life of your components, Greene Tweed offers a wide range of standard and custom engineered T-seals.

Greene Tweed’s engineers will work with you to develop a custom designed T-seal assembly suited to your needs.

Versatile Sealing and Scraping for Demanding Aerospace 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 Aerospace Environments

For applications requiring specialized elastomeric and/or thermoplastic properties, Greene Tweed's V-rings, adapters, and seal stacks are your best bet. These customizable, high strength sealing solutions are available in several compounds and combinations designed to withstand extreme temperatures, corrosive chemicals, and other damaging contaminants.
