Product Questions & Answers (2)

Question by: Kent B on Aug 11, 2025, 9:09 AM

Got a cylinder here with a 2-inch bore and need a double-acting piston seal to replace the one that's wore out. This PSC-326 gonna fit right, or do I need to check anything before ordering?

Answer by: Customer Support on Aug 13, 2025, 6:39 AM

For a 2.00-inch bore, this seal is built to fit with a piston diameter of 1.998 inches and a groove diameter of 1.625 inches. The piston diameter tolerance runs +0/-0.002, so your actual piston needs to fall within that range. One thing worth knowing is that those piston diameter dimensions are based on pistons without wear rings, so if yours has wear rings installed, that changes the fit calculation.

Question by: Neal P on Sep 1, 2025, 2:49 PM

got a cylinder with a 2 inch bore, is this the right piston seal for it?

Answer by: Customer Support on Sep 3, 2025, 6:15 AM

For a 2.00 inch bore, this seal matches that bore size and is a double-acting piston seal. It is built around a 1.625 inch groove diameter and a piston diameter (F) of 1.998 inch with a +0/-0.002 tolerance, so it is meant to fit that style of piston and groove setup.
