Question by: Cody K on Nov 29, 2025, 1:13 PM
what's the pressure rating on this expander, and is it gonna hold up on a high-demand hydraulic line?
Answer by: Customer Support on Nov 30, 2025, 6:25 PM
Rated at 2,500 psi maximum dynamic pressure, this fitting is built for demanding hydraulic systems. The straight steel construction keeps it solid under sustained load, so it's not going to be the weak point in a properly assembled line.
