Description
Keep Excess Pressure in Check!

“Guessing pressure thresholds with uncalibrated relief valves constantly led to messy fluid overflow and ruined hydraulic seals in my shop. This Poppet-Style Adjustable Pressure Relief Valve 100-300 PSI features a clear knurled adjustment knob that makes dialing in my exact relief point quick and foolproof.” — Clifford B.
