Air Hose & Tool Quick Couplings (Pneumatic, Air), Industrial Interchange - 20 Series Couplers

Brand: Parker Hannifin

Parker's general-purpose pneumatic, air quick couplers and nipples are ideal for use across a spectrum of applications where low pressure air or fluid lines require fast and easy connection and disconnection.

20 Series Quick Couplers (pneumatic, air) up to 300 psi connect with Industrial Interchange Nipples. 

Couplers are manual sleeve, single shut off couplers that mate with nipples conforming to A-A-59439 (MIL-C-4109F, ISO 6150-B) standards.  

20 Series couplers have steel, tubular style valves that deliver high flow with minimal pressure drop. An integral sleeve guard helps to resist accidental disconnection when in use. 

Couplers are available in a range of sizes, materials, and fitting ends to be versatile for use in a wide variety of applications with air or fluid pressures up to 300 psi.
