4.3 Connection to the Bulkhead Fitting
 Trim the air line to length using a sharp knife.
 Assemble an aluminium washer onto the banjo bolt and insert
through the banjo fitting. Assemble second aluminium washer and
tighten into bulkhead fitting using a 14mm [9/16”] spanner. (Fig.20.)
 Apply thread sealant to the tapered thread of the compression fitting
body and screw into the banjo fitting. Tighten using a 12mm spanner.
 Insert the outer compression nut and ferrule over the air line. Ferrule
should be orientated as per Fig.20.
Figure
20.
 Push the airline into the compression fitting body and screw the outer
nut down onto it. Using a 12mm spanner, tighten the outer nut onto
the compression fitting body.
NOTE : Some force is required to crush the ferrule, however the
outer compression nut will tighten against a stop. Over
tightening will not create a better seal.
 Secure any loose sections of tube with a cable tie.
NOTE : When right angle routing of the tube is not required,
screw the compression fitting body straight into the
bulkhead fitting body (Fig.Error! Reference source not
found.).
