Before inserting the pipe into the fitting, screw the lock nut up against the tooth of the self-locking device and no further. The tube is inserted into the fitting up against the setback, over the seal . To ensure that this is done you can check by creating a mark on the tube starting from end to the measurement "L" shown in the table below.

The "SICOAIR" blue R235 locking key has a break that turns out to be the template to mark the correct reference position of the pipe in the fitting.
To facilitate the insertion of the pipe into the fitting, we recommend that you lubricate the outside of the pipe and the inner seal of the fitting itself. Lubrication in addition to facilitating the insertion of the pipe into the fitting optimises the operation of the seal avoiding damage over time.
NEUTRAL GREASE OR VASELINE
Use neutral grease or Vaseline
Lubricate the seal inside the fitting
Lubricate the outer part of the pipe
Perform the insertion
You can also use spray lubricants, as long as they are neutral or Vaseline.
In the event the absence of any type of lubricant in the system is specifically required, the insertion of the pipe into the fitting can be performed without the help of lubricants.
