What kinda temps can this seal handle, cause things get hot where I'm workin?

Answer by: Customer Support on Oct 19, 2025, 6:29 AM

This Piston T-Seal can handle temperatures ranging from -65°F to 220°F, so it should hold up well even in pretty extreme conditions.

Question by: Wayne P on Jan 15, 2026, 6:42 AM

got a cylinder with a 1.50 bore and an o-ring groove, is this the right t-seal for that setup?

Answer by: Customer Support on Jan 17, 2026, 7:08 AM

For a 1.50 inch bore with an O-ring groove, this piston T-seal is sized for that application and is listed as a Hercules Sealing Products piston T-seal (catalog C1DM26). It uses hard plastic back-up rings with a Buna-N rubber sealing element.

Question by: Warren S on Jul 2, 2025, 8:31 PM

What's this seal rated for pressure-wise, and will it hold up in a system running close to max?

Answer by: Customer Support on Jul 4, 2025, 8:34 AM

Rated from 0 to 10,000 PSI, so it covers a wide range of hydraulic system demands. Running near the top of that range isn't unusual in heavy-duty industrial setups, and the combination of Buna-N rubber with hard plastic back-up rings is what keeps it from extruding or failing under that kind of load. As long as your system stays within that pressure ceiling, you should be in good shape.
