Industrial interchange aluminum/steel quick-connect 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. Aluminum/steel alloy couplings combine lightweight, corrosion-resistant aluminum with stronger, high-temperature steel.,All 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. Couplings deliver high air flow with minimal pressure drop for efficiency. Sleeve guards prevent accidental disconnection. These multipurpose couplers connect air tools and hoses to compressed air supplies for paint sprayers, blow guns, and cleaning equipment.
