Why John Guest Push-Fit Fittings Stand Out
For installers who need speed and reliability, push-to-connect solutions change how lines get built. They pair straightforward assembly with trusted sealing technology so crews use less time per connection.
Tool-Free, Quick Easy Installs With A Secure Lock
With Speedfit and ProLock, quick easy assembly can trim installation time by up to about 40%. Their design grips tubing and pipe with low insertion force and a reliable locking action.

Tips To Install Secure, Push-Fit Connections
Small prep steps make push-fit connections perform like pro-grade joints. A few consistent habits recommended by Installation Parts Supply can lower leaks and callbacks. By following simple habits, you keep assembly quick easy and reliable across every run.
Cutting Square, Seating Fully, And Using Locking Clips
Cut the tube square, then deburr the end so the O-ring seats evenly. A poor cut may nick the seal and result in leaks.
Mark the proper insertion depth and push in until the tube seats fully. Check by pulling back gently, then add a lock clip at critical joints for extra retention.
Choosing Between Twist-And-Lock And Superseal
Choose twist-and-lock where vibration or movement is expected. It adds retention without slowing quick easy assembly.
Select Superseal for double O-ring protection near equipment or service-critical spots. On soft tube and hot water lines, add supports to maintain steady sealing pressure.
“Cut square, push fully home, and lock with clips—these steps save time and future service calls.”
- Avoid side-loads and support long spans to reduce stress on pipe and fittings.
- Always keep parts free of debris; contamination can compromise seals and increase leak risk.
- Reference full details and view the rated temperature and pressure before using any fitting.
- Carry spare clips and release tools for quick field adjustments.
