Kleinn Safety Valve - 1/4In M NPT - 145 PSI Rated Pop-Off Valve

The Kleinn Model 52145 is a premium 145 PSI pop-off safety relief valve engineered as a critical, safety-coded 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 and is specifically designed to work with the Model 2121 pressure switch (90 PSI ON - 120 PSI OFF), automatically popping off to release a sudden burst of excess air if the pressure switch fails or if the tank surpasses safe operating limits to protect your compressor from burning out.
