Question by: Joyce P on Dec 23, 2025, 5:05 PM

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

Answer by: Customer Support on Dec 25, 2025, 12:52 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.

Question by: Floyd W on Aug 19, 2025, 9:07 AM

What bore size is this seal good for? Just want to make sure it's the right one for my cylinder.

Answer by: Customer Support on Aug 20, 2025, 6:02 PM

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.
