# Kleinn Inline Check Valve - 1/4In F NPT to 1/4In M NPT

The Kleinn Model 52831 is a heavy-duty, 1/4" inline check valve engineered to maintain consistent pressure and prevent air backflow within your onboard air system. Featuring a durable brass construction that resists corrosion and wear, this valve is designed with a 1/4" Female NPT inlet and a 1/4" Male NPT outlet for straightforward integration into your plumbing lines. By ensuring that compressed air flows strictly in a one-way direction, it effectively isolates the air tank from the compressor, reducing strain on the compressor head and preventing premature system pressure loss.
