T-Seals
Extrusion-Resistant Sealing for Hydraulic, Pneumatic, and High-Pressure Applications
Performance Seals supplies T-Seals designed to improve reliability in hydraulic and pneumatic systems. Originally developed to replace standard O-ring seals, T-Seals retain the space-saving advantages of O-rings while addressing two of their most common failure modes: extrusion and instability in the groove.
What Are T-Seals?
T-Seals are engineered sealing solutions designed to preserve the sealing performance of O-rings while eliminating key reliability issues.
They are specifically designed to:
- Prevent extrusion through the gap between static and dynamic surfaces
- Eliminate instability in the groove that can lead to spiral or twisting failure
T-Seals maintain the compact groove design of an O-ring while delivering improved performance in demanding applications.
Key Takeaways
- Designed to replace O-rings in hydraulic and pneumatic systems
- Help eliminate extrusion and spiral failure

Materials
T-Seals are available in a range of elastomer compounds to meet application requirements:
- HNBR (Hydrogenated Nitrile)
- FKM (Fluorocarbon)
- FFKM (Perfluoroelastomer)
Performance Seals can help customers evaluate these factors when identifying the right solution.
Common Applications
- Running tools
- Wellheads
- Valves
- Actuators
- Blowout Preventers (BOPs)
- Hydraulic and pneumatic systems in oil and gas applications
Retrofit & Design Flexibility
T-Seals are designed to fit into existing O-ring grooves, allowing for retrofit without machining or major hardware modifications. This simplifies both field upgrades and new equipment manufacturing.
The product series is available for standard BS-1806 grooves or can be custom-designed for specific applications and gland geometries.
