Compatibility checklist
- ✓Your fitting is designed for 1/4″ OD tubing
- ✓The application uses a compatible cold-water filtration line
- ✓The tube can be routed without excessive kinking or crushing
- ✓The selected length provides enough extra tubing for clean routing and future service
Installation
A square cut and full insertion are essential for a reliable push-fit connection
1
Measure the Run
Route the tubing with smooth curves and leave enough extra length for future servicing.
2
Cut at 90°
Use a tubing cutter or suitable sharp blade to make a clean, square cut without crushing or deforming the tube.
3
Push Fully Into the Fitting
Insert the tubing straight into the compatible quick-connect fitting until it passes the internal seal and seats fully.
4
Check the Connection
Give the tubing a gentle pull to confirm retention, then pressurize slowly and inspect the connection for leaks.
