Question by: Billy B on Jul 8, 2025, 11:56 AM

Will this piston t-seal hold up in a hydraulic system running at a pretty constant 5000 PSI?

Answer by: Customer Support on Jul 9, 2025, 12:21 PM

This T-seal is made with hard plastic back-up rings and a Buna-N rubber seal, so it can handle pressures from 0 to 10,000 PSI without any problem. It's built for heavy-duty hydraulic applications.

Question by: Roy F on Jan 16, 2026, 7:00 PM

got a cylinder with a 6 inch bore. is this the right t-seal for a piston with an o-ring groove?

Answer by: Customer Support on Jan 18, 2026, 2:01 PM

The key callout on this one is the 6.00 inch bore and the fact it is a piston T-seal style made for an O-ring groove. If your piston setup is a 6 inch bore application that uses a T-seal in an O-ring groove, this matches that size and style.
