Compressed Air Pressure Reducer: The compressed air regulator is an effective maintenance unit for use on compressors. The pressure regulator is made of high-quality metal, strong and durable, and has good sealing performance. Compressed Water Separator with Pressure Gauge: The compressed air pressure reducer has an accurate scale that allows for better observation of the air pressure. During use, it can maintain sufficient constant pressure. 1/4" Compressed Air Reducer: The 1/4" pressure reducer fits most available air compressors - European standard. Maximum pressure: 120 psi. Easy to use: The 1/4" compressed air pressure reducer can be screwed directly onto the threaded interface of the compressor and other machines, and is easy to install and disassemble. The value on the pressure gauge allows the valve to be used to adjust the closing and starting of the air compressor. Application scenario: For air compressor, pneumatic tool, gas connection device, efficient. 1 compressed air
