Product Questions & Answers

these are buna n material, right? just want to make sure before i order a handful of em for our motor rebuilds

Question by: Jean P on Aug 16, 2025, 9:45 AM

Buna N is correct. The 70 in the name refers to the durometer hardness, which is a standard Shore A rating for general-purpose hydraulic sealing applications. Buna N at that hardness holds up well against petroleum-based hydraulic fluids, which makes it a common go-to for Char-Lynn and Danfoss motor service work.

i’m trying to match up an o-ring, is this one actually a Buna-N 70 seal?

Built as a Danfoss and Eaton spare part, this is a Buna-N 70 O-ring under the Eaton Char-Lynn brand.
