John Guest tube cutter
Manual tool for preparing flexible tubing before fitting it into push-fit connectors. A clean, square cut helps the tube insert correctly and allows the sealing area to work on an even surface.
Why a good tube cut matters
An angled, crushed, scratched or burred end can make insertion difficult and contribute to sealing problems. Cutting with a suitable tool reduces these errors.
How to use it
Mark the cutting point, place the tube perpendicular to the blade and make a clean cut without twisting it. Before connecting, visually inspect the end and discard any deformed section.
Good practices
Do not use a damaged blade and avoid crushing the tube while cutting. Keep the tool clean and protected when not in use.
