What is Chicago coupling?
The Chicago coupling is known as air hose coupling or America air coupling. We adopt carbon steel or stainless steel as its main material and produce the coupling according to DIN 3489. Thanks to its convenient installation performance, it is widely used as the connection coupling for industrial compressed air hoses and water hoses.
The available coupling size range from 1/" to 2".
