seal material on this one, is it buna-n? got some fluid compatibility questions before i pull the trigger
Answer by: Customer Support on Jan 27, 2026, 2:20 PM
Buna-N is confirmed as the seal material on this valve. That's a standard nitrile compound, which holds up well with most petroleum-based hydraulic fluids. Worth cross-checking against whatever fluid your system runs, but for conventional mineral oil hydraulic systems it's a common and reliable choice.
