ARO Quick-Connect Air Couplings

Available38 products
ARO quick-connect air couplings connect air tools and hoses to compressed air supplies. Also known as Milton A-style couplings, they are used on pneumatic lines in furniture building, construction, and factory automation.

ARO Aluminum Quick-Connect Air Coupling Bodies

ARO Aluminum Quick-Connect Air Coupling Bodies
ARO aluminum quick-connect air coupling bodies are the female end of coupling sets. Also called sockets, they accept coupling plugs (nipple or male ends) for use with pneumatic lines. Aluminum couplings are lightweight and resist corrosion, but are more susceptible to scratches and wear unless alloyed with other metals for strength.

ARO Aluminum Quick-Connect Air Coupling Plugs

ARO Aluminum Quick-Connect Air Coupling Plugs
ARO aluminum quick-connect air coupling plugs are the male end of coupling sets. Also called nipples, they're inserted into the coupling bodies (female ends) for use with pneumatic lines. Aluminum couplings are lightweight and resist corrosion, but are more susceptible to scratches and wear unless alloyed with other metals for strength.

ARO Aluminum/Steel Quick-Connect Air Coupling Plug Kits

ARO Aluminum/Steel Quick-Connect Air Coupling Plug Kits
ARO aluminum/steel quick-connect air coupling plug kits contain both ends (female and male) of the coupling. Kits often contain multiple sizes. Aluminum/steel alloy combines lightweight, corrosion-resistant aluminum with stronger, high-temperature steel for high-humidity environments.

ARO Brass Quick-Connect Air Coupling Bodies

ARO Brass Quick-Connect Air Coupling Bodies
ARO brass quick-connect air coupling bodies are the female end of coupling sets. Also called sockets, they accept coupling plugs (nipple or male ends) for use with pneumatic lines. Brass, an alloy of copper and zinc, is strong, highly conductive, and resists corrosion. Brass is softer than other metal plugs and sockets for better threading together. Compatible with copper or zinc piping, brass maintains its durability and machineability at high temperatures.

ARO Stainless Steel Quick-Connect Air Coupling Plugs

ARO Stainless Steel Quick-Connect Air Coupling Plugs
ARO stainless steel quick-connect air coupling plugs are the male end of coupling sets. Also called nipples, they're inserted into the coupling bodies (female ends) for use with pneumatic lines. Stainless steel is durable, resists corrosion from caustic chemicals, corrosive fluids, oils, and gases, and withstands pressure and high temperatures.

ARO Steel Quick-Connect Air Coupling Bodies

ARO Steel Quick-Connect Air Coupling Bodies
ARO steel quick-connect coupling bodies are the female end of coupling sets. Also called sockets, they accept coupling plugs (nipple or male ends) for use with pneumatic lines. Steel is a mix of iron and carbon made hard and resilient with a wide working temperature range and corrosion resistance for high-humidity environments.
