Would this U-seal hold up in a hydraulic system running around 5000 PSI?
Question by: Bobby S on May 9, 2025, 11:50 AM
Urethane construction supports a pressure range of 0 to 6,000 PSI, so it should work fine in your system.
Answer by: Customer Support on May 11, 2025, 6:09 AM
seal's rated up to 6,000 PSI, that hold true runnin a hydraulic cylinder pretty hard over long shifts, or is that more of a peak number?
Question by: Bobby P on May 4, 2025, 8:58 PM
Urethane holds up well under sustained pressure loads, and the 6,000 PSI rating on this one covers the full working range, not just a momentary spike tolerance. Running it hard through long shifts falls well within what this material is built to handle. The beveled lip design also helps maintain consistent sealing across repeated cycles, so pressure doesn't have to drop off before the seal does its job.

got a cylinder with a 1.25 rod and a 2 inch bore, is this the right u-seal size?
Question by: Patty B on Jun 7, 2025, 2:32 PM
The key dimensions on this seal are 1.25 inch ID and 2.00 inch OD, with a 0.375 inch cross section and 0.375 inch height. If your application calls for those exact sizes, this U-seal matches.
