What to check before choosing
Tube diameter
Before purchasing, always check the tube diameter, such as metric or inch sizes. An incompatible tube can cause leaks or prevent correct installation.

Correct tube cutting
The tube must be cut straight, without crushing or burrs. An incorrect cut can compromise fitting sealing and cause leaks over time.

Installation and maintenance
Tube insertion
The tube must be inserted fully into the fitting. After insertion, it is useful to pull the tube gently to check that it is properly locked.
