# Kleinn Safety Valve - 1/4In M NPT - 155 PSI Rated Pop-Off Valve

The Kleinn Model 52155 is a premium 155 PSI pop-off safety relief valve engineered as a critical pressure protection device for your onboard air system. Featuring a durable heavy-duty brass construction that resists corrosion, this valve is designed with a standard 1/4" Male NPT fitting to easily thread directly into your air tank. It acts as an essential safeguard for your pneumatic setup by automatically popping off to release a sudden burst of excess air if the system's pressure switch fails or if the tank surpasses safe operating limits, protecting your compressor from burning out and preventing dangerous over-pressurization.
