Got a cylinder rod that's 2.13 inches across, will this u-seal fit up right on it?
Question by: Floyd E on Aug 12, 2025, 7:40 AM
For a rod measuring 2.125 inches in diameter, the inner diameter on this seal matches up exactly at 2.125 inches, so the fit should be right on. The outer diameter runs 2.500 inches, and the overall height is 0.25 inches. Just make sure your housing bore is machined to accept that 2.500 inch OD and you should be in good shape.
