Got a cylinder that takes a 0.38 inch bore seal with a 0.63 inch OD, will this u-seal fit that setup?
Question by: Todd A on Feb 26, 2026, 12:49 PM
Those dimensions line up exactly. The seal runs 0.375 inches ID, 0.625 inches OD, and sits 0.125 inches tall with a matching cross-section, so if your cylinder calls for those specs, you're good to go. The beveled lip design also helps it break the fluid film cleanly, which matters for keeping leakdown in check over time.
