Compact yet incredibly tough, this 1/4" MPT safety relief valve delivers critical over-pressure protection for tight industrial plumbing spaces. Designed for applications pushing between 1,000 and 6,000 PSI, it prevents catastrophic line ruptures and manifold fractures by opening precisely when pressure limits are breached. This is a must-have safety component for professional pressure wash trailers, hydraulic test benches, and fluid injection systems.
