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.19.)
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.19.

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.19.).
