got a 6 inch bore cylinder, is this the right piston seal or am i gonna be fighting it?

Question by: Denise P on Oct 21, 2025, 2:22 PM

The key numbers are a 6.00 inch bore, a piston diameter “F” of 5.999 inches, and a groove diameter (E) of 5.238 inches. If your piston and groove match those dimensions and tolerances, this Style 1850 seal is the correct size for that setup.
