Product Questions & Answers

Will this O-ring work with Eaton Char-Lynn products?

It's an Eaton Char-Lynn spare part, so it should fit right in with your other Eaton Char-Lynn gear.

Is this the Buna N 70 durometer o-ring for Eaton Char-Lynn motors, or is it a different compound?

Question by: Steve R on Feb 8, 2026, 9:26 AM

Buna N at 70 durometer is exactly what this is, sourced under the Eaton Char-Lynn / Danfoss Power Solutions part number 8761-143. Buna N is a nitrile rubber compound that holds up well in petroleum-based hydraulic fluid environments, and the 70 durometer rating puts it in the standard medium-hardness range you'd expect for most hydraulic sealing applications in that product family.
