pressure range on this seal, does it really hold up all the way to 6,000 PSI or is that just a spec sheet number?
Question by: Gene W on Apr 17, 2025, 6:20 PM
Urethane seals like this one are well-suited for high-pressure hydraulic service, and the 0 to 6,000 PSI rating on this part is a genuine operating range, not a theoretical ceiling. The beveled lip design helps with film breaking across that full range, which is part of why urethane gets used in demanding cylinder applications. That said, staying within the rated pressure keeps the seal performing the way it should over time.
