got a cylinder leaking and i pulled out a seal marked U25-5.25. is this the same Hercules U-cup?
Answer by: Customer Support on Nov 25, 2025, 6:41 AM
Match-up wise, the part on this item is Hercules Sealing Products U-Cup with supplier part number U25-5.25, and it is also cross-referenced as alternate part number C1DP70. If your old seal is marked U25-5.25 or you are replacing C1DP70, it lines up as the same part.
