T-Seals & L-Seals
The ‘T’ seal consists of a T-shaped cross section elastomer combined with two thermoplastic Back-up Rings, designed for bi-directional differential pressure.
The ‘L’ seal consists of an L-shaped cross section elastomer combined with one thermoplastic Back-up Ring, designed for differential pressure from one side.
These seals were originally developed to preserve the advantages of O-rings in dynamic fluid power applications while ending two of their most serious reliability problems:
Extrusion through the gap between static and dynamic surfaces, and instability in their grooves, the latter leading to spiral or twisting failure.
This type of seal eliminates both of these problems while retaining the space-saving attributes of the compact O-ring groove.
Above all, the T-seal & L-Seal meet or exceed the O-ring’s outstanding ability to seal at all pressures and temperatures.
Features & Benefits
Designed to retrofit standard o-ring grooves
Square section prevents rolling in the groove, eliminating spiral failure
Reliable low pressure seal
Reliable high pressure seal
Various materials can be combined suiting the seal to the application
As dynamic seals, typically in reciprocating applications, where friction is a concern
