Question by: Neal P on May 27, 2025, 10:42 AM
Will this O-ring work with Eaton Char-Lynn products?
Answer by: Customer Support on May 29, 2025, 6:52 AM
It's an Eaton Char-Lynn spare part, so it should fit right in with your other Eaton Char-Lynn gear.
Question by: Steve R on Feb 8, 2026, 9:26 AM
Is this the Buna N 70 durometer o-ring for Eaton Char-Lynn motors, or is it a different compound?
Answer by: Customer Support on Feb 10, 2026, 8:13 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.
