WELWIK 2PCS 1/4 Inch NPT 175 PSI Air Compressor Relief Safety Valve Automatic Air Vent with Sealed Threaded Lock Suitable for High Temperature Applications

["Contents: You will receive 2 pieces 1/4 inch NPT threaded pressure-reducing valves, complete with thread-sealing compound. This quantity is sufficient to meet your day-to-day needs and makes replacement easy.","Reliable and robust: These NPT threaded air compressor components are made from corrosion-resistant brass, offering high-temperature resilience and low magnetic permeability. They are suitable for venting air, water and oil from air compressors.","Product information: The safety valve has a working pressure of 175 psi and an operating temperature range of -65 degrees Fahrenheit to +250 degrees Fahrenheit.","Useful features: This air compressor pressure valve reduces overpressure or vacuum conditions within the system. When the pressure inside the compressor housing exceeds the preset level, the valve opens to allow liquid or gas to escape, thereby reducing the pressure. When the pressure falls below the preset level, the valve opens to allow liquid or gas to enter the system, and then closes when the reset pressure limit is reached.","Note: The 1/4 inch brass air pressure relief valve is suitable for high-temperature applications up to 250 degrees Fahrenheit."]
