Pneumatic QC Selection
Back to Product Overview |
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.

QC Selection Tips
When ordering quick couplers, consider the following:
- Functional requirements of the coupling
- Maximum working pressure of the application
- Coupler seal & body material compatibility with the system’s fluid
- Is the application static or dynamic?
- Size of coupler & hose
- Maximum allowable pressure drop
- Requirement to connect & disconnect under pressure
- Media temperature
- Ambient temperature
- End configuration requirements
- Need for industrial interchange QC
- Effects of air inclusion & fluid loss
If several different series of couplings are being used in your plant or shop, consider using Industrial Interchange Nipples. Industrial Interchange Nipples work with the following couplers: Parker 20 Series, Parker HF Series, Parker 30 Series, Parker Universal Couplers, and Parker E-z-mate Series.
Parker Industrial Interchange nipples are also interchangeable with similar nipples manufactured by other quick disconnect manufacturers conforming to A-A-59439 (formerly known as MIL-C-4109F), ANSI/(NFPA) T3.20.14-1990, or ISO6150-B requirements.
