What's the deal with that beveled lip? Does that help it seal better or something?
Question by: Dustin C on Mar 19, 2026, 1:03 PM
That beveled lip is designed to enhance film breaking. That ensures more efficient sealing, especially when there's pressure involved.
Answer by: Customer Support on Mar 21, 2026, 6:34 AM
Trying to figure out the temp range on this seal before I order a bunch of 'em. We run pretty hot in the summer and cold in the winter out at the facility.
Question by: Clint D on Feb 15, 2026, 11:39 AM
Rated from -65°F up to 220°F, so it handles a pretty wide swing. Whether you're dealing with deep winter cold or summer heat pushing equipment temps up, this seal stays in its operating range without issue. For most industrial hydraulic setups running through seasonal extremes, that range covers it comfortably.
