got a u-cup spot that measures right around 5/16 on the rod, is this seal the one with the 0.3125 ID and 0.563 OD?
Question by: Ricky G on Aug 11, 2025, 6:06 PM
The key numbers on this one are 0.3125 inch ID, 0.563 inch OD, and 0.125 inch height with a 0.125 inch cross section. If your groove and hardware are set up for those dimensions, it matches the 5/16-inch ID you mentioned.

these seals rated for high pressure systems or are they more of a light duty thing?
Question by: Curt P on Jul 11, 2025, 6:26 PM
Pressure range on these runs from 0 all the way up to 6,000 PSI, so they hold up well in demanding hydraulic applications. Not just light duty work. The polyurethane construction handles that range without breaking down, and the beveled lip design helps with film breaking across the pressure spectrum.
Answer by: Customer Support on Jul 13, 2025, 12:27 PM
What kinda pressure can this seal handle before it gives out?
Question by: Patty M on Dec 2, 2025, 9:49 PM
This Hercules U-seal can handle pressures from 0 up to 6,000 PSI, so it should hold up in demanding applications.
