Product Questions & Answers (3)

Question by: Scott K on Nov 9, 2025, 6:55 AM

got a cylinder with a 2.50 bore, is this Style 1400 seal the right size for it?

Answer by: Customer Support on Nov 10, 2025, 3:07 PM

It matches a 2.50 inch bore and is intended to run on a 2.496 inch piston diameter with a ±0.001 tolerance. The groove diameter spec is 2.108 inches, and the bore tolerance called out is ±0.002, so it is aimed at a fairly tight, standard hydraulic gland setup.

Question by: Shane R on Sep 20, 2025, 3:58 PM

what temp range does this seal handle? got some equipment runnin pretty hot and need to know before i order

Answer by: Customer Support on Sep 22, 2025, 11:01 AM

Rated from -40°F up to 220°F, so it covers a solid range on both ends. If your equipment stays under that 220°F ceiling, you're in good shape. Anything pushing past that threshold regularly would be outside what this seal is built for.

Question by: Vince S on Jun 30, 2025, 6:24 AM

So, this seal fits a 2.5 inch bore, right? Just wanna make sure before I order.

Answer by: Customer Support on Jul 2, 2025, 6:39 AM

That's correct. This Style 1400 piston seal is designed for a 2.50 inch bore diameter.
