Question by: Warren O on Jan 5, 2026, 4:18 PM
Got an old cylinder that takes a 568-162 o-ring and I can't find it by that number anywhere local. This the same thing just listed different?

Same ring, different numbering systems. The part number 568-162 is the supplier part number on this one, so you're looking at an exact match. It also cross-references as C1CE31, MI-08740400, and MINO-00407X90400, so if your old parts book or machine manual shows any of those numbers, you're good to go.

got a groove set up for a 568-162, is this the same size o-ring?
Answer by: Customer Support on Nov 12, 2025, 12:40 PM
Match it by the 568-series size callout. This one is a 568-162 and it has a 5-15/16 inch outside diameter with a 3/32 inch cross-section, so it lines up with a groove meant for that standard size.
