General Purpose – Push-To-Connect
UC Series
Features
• The 1/4" UC Series Coupler will accept the industrial
interchange, [(MIL-C-4109F) and (ANSI/(NFPA) T3.20.14-
1990)], 10 Series (Tru-Flate) and the 50 series (ARO 210)
style nipples.
• The coupler features automatic push-to-connect operation,
high flow machined “window valve,” corrosion resistant solid
brass construction and a sleeve guard which helps prevent
accidental disconnects and protects the sleeve from
damage.
• While the best quick coupling performance is obtained by
matching like series couplers and nipples, the universal
coupler permits multiple series nipples to mate with one
coupler.
