Product Questions & Answers

got a cylinder with a 5 inch bore. is this the right Style 2700 piston seal for it, or am I gonna be fighting the fit
Question by: Joyce P on Dec 23, 2025, 5:05 PM
It matches a 5.00 inch bore and is sized around a 4.999 inch piston diameter with a +0/-0.014 inch tolerance. The groove diameter called out for this seal is 4.44 inches, and the groove width tolerance is ±0.002 inches, so those are the key numbers to line up with your piston and groove.

What bore size is this seal good for? Just want to make sure it's the right one for my cylinder.
Question by: Floyd W on Aug 19, 2025, 9:07 AM
It's designed for a 5-inch bore. The piston diameter itself is just a hair under that, at 4.999 inches, with a tolerance of +0/-0.014 inches.
