What are Quick Coupling
All the USA industrial interchange quick-connect air couplings fit the same size industrial interchange plugs no matter the pipe size or barbed hose ID. Also called Milton M or Mil-Spec (meet MIL-C-4109), these couplings are the most common interchange type.
The Longwei LU17 series multipurpose couplers connect air tools and hoses to compressed air supplies for paint sprayers, blow guns, and cleaning equipment.
Industrial interchange quick release air coupling bodies are the female end of coupling sets. Also called sockets, they accept coupling plugs (nipple or male ends) to connect tools to air, water, or fluid lines.
