Will this U-seal hold up in a hydraulic system that runs pretty hot, say around 200 degrees F?
Question by: Dustin E on May 25, 2025, 6:09 AM
This Hercules U-seal is made from urethane and can handle temperatures from -65°F all the way up to 220°F, so 200 degrees should be no problem.

Got a cylinder with a 2-inch rod and a 2.625 bore on the gland. This the right seal for that setup?
Question by: Kirk P on Sep 10, 2025, 12:29 PM
For a 2.00 inch rod diameter with a 2.625 inch gland bore, yeah, that's exactly what this seal is built for. The 2.00 inch ID and 2.63 inch OD match those dimensions directly, and the 0.3125 inch cross section gives you a consistent fit in the groove. Urethane holds up well in hydraulic rod applications, so you should be in good shape there.

trying to swap out a worn u-seal, are these dimensions 2.625 OD and 2.00 ID with about a .31 height?
Question by: Kurt R on Feb 12, 2026, 8:53 PM
Fit comes down to the measured sizes, and this one is sized at 2.625 inch OD, 2.00 inch ID, with a 0.3125 inch height and 0.3125 inch cross section.
