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
