General Purpose-Push to Connect Pneumatic Quick Couplers | Parker UC Series

Parker UC Series Female Pipe Thread Couplers COUPLERS

Sizes 1/4"

Select Another Pneumatic QC
The 1/4" UC Series Couplers 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 being damaged.
  • 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.
