Pneumatic Quick Disconnects | Parker

Quick couplers | Parker  Pneumatic QC Selection


Back to Product Overview

Pneumatic quick couplers (also referred to as air couplers, or pneumatic quick disconnects), are primarily used for pneumatic applications, connecting air tools, hoses, or other implements to compressed air supplies. They are also used with other gases, and (with the exception of the E-z-mate Series) can be used with low pressure fluids.

The coupler half contains a shut-off valve that is automatically opened when a mating nipple is inserted and automatically closes when the nipple is removed.

Parker pneumatic couplings come in three basic designs: general purpose/manual connect, general purpose/push-to-connect, and special purpose.

The standard seal material for all Parker single shut-off couplers is Nitrile. Ethylene Propylene, Fluorocarbon, and Neoprene seals are available as options. Please consult the comprehensive Fluid Compatibility Chart for more information on seal and body material selection – or contact us for further assistance in selecting the appropriate seal material.
