Product Questions & Answers

Reckon this would be alright for hydraulic oil? I don't want it eating up the seals.

Question by: Bobby P on Dec 31, 2025, 7:27 PM

Yes, Buna-N seals are compatible with hydraulic oils. The valve housing is cast iron and the piston is hardened steel, all suitable for use with hydraulic fluids.
