Hey, just wanna make sure this'll fit my cylinder – got the number right here: US-95URE/NBR-11/16X15/16X1/8.

This Hercules seal is indeed the US-95URE/NBR-11/16X15/16X1/8, so if that's what you need, it should fit right up.

got a seal marked US-95URE/NBR and these same size numbers, 11/16 x 15/16 x 1/8. is this the right replacement part?

Answer by: Customer Support on Jun 25, 2025, 9:28 PM

Match-up is based on the full identifier and size. This product is a Hercules Sealing Products seal labeled US-95URE/NBR with the size 11/16X15/16X1/8, and it cross-references to supplier part number U12-0.68-SQB (SKU U12-0.68-SQB). If your old seal carries that same callout, it is the same part.

part number U12-0.68-SQB, that's the Hercules seal in NBR, is that the right one to grab when i'm replacing a worn rod seal in a hydraulic cylinder that's been running mineral oil?

Answer by: Customer Support on Aug 11, 2025, 6:41 PM

NBR is a solid choice for mineral oil hydraulic systems, and Hercules Sealing Products has a solid reputation for holding up in that kind of environment. The U12-0.68-SQB carries the URE/NBR material designation, which combines urethane and nitrile rubber construction. For a rod seal replacement in a standard mineral oil circuit, that material pairing is a practical fit. Just make sure your bore and rod dimensions line up with the 11/16 x 15/16 x 1/8 inch sizing before you order.
