Product Questions & Answers (1)

Question by: Warren K on Mar 25, 2026, 12:29 PM

I’ve got a cylinder with a 7.00 bore, is this PS2700-112 piston seal the right fit or am I gonna be fighting it?

Answer by: Customer Support on Mar 26, 2026, 9:54 PM

It matches a 7.00 inch bore with a bore tolerance of ±0.002 inches, and it’s sized around a 6.999 inch piston diameter with a +0/-0.014 inch tolerance. The seal cross section is 0.142 inches and seal height is 0.362 inches, so it’s meant to sit in that geometry rather than be forced into an out-of-spec bore or piston.
