Question by: Freddie H on Jan 15, 2026, 9:34 AM
What size bore is this seal made for? Just want to make sure it'll fit my cylinder.
Answer by: Customer Support on Jan 16, 2026, 1:48 PM
This seal is designed for cylinders with a 4.50 inch bore diameter. The tolerances are plus or minus 0.002 inches, so you have a little wiggle room.
