CLEANING THE TUBE AND COUPLING
3
To avoid potential problems with pneumatic equipment, check the
appearance of the sealing area surfaces and eliminate residue, dust and
shavings inside the pipe after cutting.
We highly recommend cleaning the components – especially the ends of
the tubes and the insides of the couplings – with a clean cloth and a gentle
degreaser formulated for surfaces. We recommend using soapy water
(Ref : PPS AL), as grease and lubricants impair the quality of the products
during their service life.
Avoid damage from scratches or impacts.
ASSEMBLE COUPLING ON TUBE

1_Loosen the nut about one turn (do not remove it).
2_Check for contaminants inside the fitting (seal and teeth).
3_ Make sure that all the components are inside the coupling and
correctly positioned. Make sure that the retaining teeth are in the
same direction as shown on the diagram below.
4_ Before inserting the tube, tighten the outer nut by hand in order to
take up any play between the components.
5_ With a felt-tip pen, mark the full length of the pipe that will be
nesting inside the fitting. The use of a marker on the coupling or
the PPS1 CLE wrench makes it easier to determine the insertion
depth.
The tightening of the nut is included in this nesting length.

• Draw the insertion length on the tube for each new connection to be made
• Put lubricant on tube end and into the fitting with the assembly fluid
presence or use of any kind of grease leads to uncertainty and reduces

• Check the insertion length from the stop shoulder inside the coupling
to the top of the nut
(PPS AL)
It is forbidden to use lubricants, oils or greases if you are uncertain
about their chemical compatibility. We advise using soapy water, as the
the connection capacities between the tube and the couplings.
When a doubt, contact us!
6_ Insert the pipe in a slight twisting motion until it reaches the back of
the fitting
