To disconnect a quick disconnect fitting, you generally need to engage a release mechanism while simultaneously pulling the connected item free. For many common push-to-connect quick disconnect fittings, this involves pressing a collar or ring inward towards the fitting body while pulling the tubing or hose outward.
Steps for Disconnecting Quick Connect Fittings
Based on common practice and the method described in the reference, disconnecting this type of fitting is a straightforward process:
- Press the collar inward: Locate the collar or ring at the base of the fitting where the tubing enters. Apply firm pressure inward towards the fitting body. This action releases the internal gripping mechanism that holds the tubing in place.
- Pull the tubing outward: While holding the collar pressed inward, grasp the tubing or hose firmly and pull it straight out of the fitting.
- Perform Simultaneously: It's crucial to simultaneously press the collar inward and pull the tubing outward for the disconnection to occur smoothly.
This technique is widely used for various applications, including:
- Water filtration systems
- Pneumatic air lines
- Beverage dispensing equipment
- RO (Reverse Osmosis) systems
Remember that the specific design might vary slightly between manufacturers, but the principle of releasing an internal grip by pressing a collar or button is common for many quick disconnect styles used with flexible tubing. Always ensure the system is depressurized before attempting to disconnect fittings.
