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 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). Steel is hard and resilient with a wide working temperature range.
