TIPS AND SUGGESTIONS

Connection of pipes and fittings
Where 3/8" BSP rigid pipes or hoses are used in connections between pipes and fittings
(diameter of approximately 9.7 mm), carefully respect the pipe dimensions. Pipes of a
lower diameter do not guarantee a pressure/vacuum seal. Pipes with a higher diameter,
conversely, have to be forced into their housing and this adversely affects installation
of retaining rings (3 and 4) for a poorer seal.
When working on fittings that are already installed, always replace retaining rings (3 and
4) 65-AC and 65-AA with equivalent new parts. When installing, ensure that the end
of pipe (1) fully enters the housing of fitting (5) to ensure maximum grip. If a flexible
tube is used, tighten pipe collar (2) firmly by hand; for better performance, we recommend
the use of accessory FAB0040 (5), which should be inserted into the front of the
flexible tube. However, if a rigid tube is used, close the pipe collar (2) using a wrench, in
this case close with a compression torque wrench between 1.5 and 2.5 Nm.
