Question by: Ricky R on Feb 8, 2026, 10:53 AM

Reckon these'd hold up okay in a hydraulic cylinder for farm equipment? We run it pretty hard out in the fields.

These U-seals should work well in hydraulic cylinders, especially where you're using petroleum-based hydraulic fluids. They're rated to handle pressures up to 1,000 PSI and temperatures from -40°F to 250°F, so they ought to stand up to a good bit of work.
