Product Questions & Answers

what's the o-ring material on this fitting, and will it hold up with standard hydraulic fluid?

Question by: Judy W on Feb 13, 2026, 8:21 PM

NBR is the seal material here, which handles petroleum-based hydraulic fluids just fine in most industrial setups. It's a common and dependable choice for everyday hydraulic lines where you're not dealing with anything exotic like phosphate ester or certain synthetics.
