How to Cut Tubing

  3. Release the handles to allow the spring mechanism to reopen, then remove the cleanly cut tubing ready for John Guest Quick Connect Fitting installation.
COMPATIBILITY

Tubing Compatibility

This John Guest Tube Cutter works with all plastic tubing types commonly used in water filtration systems, including polyethylene, polypropylene, and nylon tubing in 1/4", 5/16", 3/8", and 1/2" outer diameter sizes. It is specifically designed to prepare tubing for use with John Guest Quick Connect Fittings, where a clean, square cut is essential for proper seal engagement and leak-free performance.

🔧 Pro tip: Always inspect the cut end before inserting into a fitting. A square cut with no deformation ensures the tubing seats fully and the O-ring seals properly. If you see an angled or crushed edge, recut the tubing 1/4" shorter.
