what's the max pressure rating on this cap nut? got some lines running pretty hard and need to know if it'll hold up
Answer by: Customer Support on Oct 30, 2025, 6:50 AM
Rated for 4,000 psi dynamic pressure, so it holds its own in high-demand hydraulic setups. That's the maximum continuous working pressure, and it's built from straight steel, which gives it solid resistance to wear over time. For most heavy-duty hydraulic lines, that rating covers a wide range of applications without issue.
