Brass 1/4″ NPT 150 PSI Air Compressor Relief Valve

Keep your air compressor running safely and efficiently with the Fyntave 2-piece pressure relief valve. Built from high-purity brass, this valve resists corrosion, handles high temperatures, and ensures reliable performance with air, water, or oil discharge. Its dual overpressure and vacuum regulation system protects your system by automatically releasing excess pressure—opening when pressure exceeds 150 PSI and sealing once it returns to a safe range.

The valve features a 1/4-inch NPT threaded design for a secure, leak-free connection to most air compressors, with quick and easy installation. Compact yet durable, it measures 35 mm (1.38″) in length and includes a two-valve pack to cover daily use and emergency replacements. Whether for industrial workshops, garages, or home setups, this valve ensures stable operation and peace of mind.
