c ) Fitting :
- Use seals designed for LHM fluid only.
- Proceed as follows for connecting a union :
• Place sleeve-seal « a » on the pipe, moistening with LHM fluid. This sleeve-seal must be set back from pipe
end.
• Centre the pipe in the bore, presenting on the centreline of the orifice and avoiding forcing ( check that pipe
end b » penetrates reduced bore « c » .
• Start screwing the union-nut by hand.
Tighten the nut moderately. Overtightening will cause a leak. by distorting the pipe.
Tightening torques :
3.5 mm pipe
}
0.8 to 0.9 m.daN
4.5 mm pipe
6 mm pipe 0.9 to 1.1 m.daN
By design, the thightness of the seals increases with pressure. Seal tightness cannot therefore be improved by tightening
the unions.
To connect a rubber pipe, insert a rubber bush of appropriate diameter, between pipe and clamping collar.
9. CHECKING ON COMPLETION OF THE WORK
Following any work on the hydraulic components or circuit, check :
a ) seal-tightness of the unions,
b ) clearance between pipes : pipes must not touch each other, or any other fixed or mobile element, and connections to
fixed or mobile elements must not be under strain.
