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.
