Follow the torques for threaded joints listed in Table 1
according to thread sizes of hose fittings to ensure
their proper assembly.
There is also an alternative procedure to obtain an
equivalent torque without using special tools: joint both
ends of the hoses to be connected, tighten a swivel nut
by hand (without using spanner) until there is
resistance on the nut. Fit two spanners (1) on the fixed
ends of the hoses and turn the swivel nut with a third
spanner (2) as many flats from wrench resistance
(FFWR) as indicated in
Table 1 .
