HOSES AND FITTINGS
NOTE
Most fluid piping system sizes are measured by dash numbers. These are universally used
abbreviations for the size of the component expressed as the numerator of the fraction with
the denominator always being 16. For example, a 04 port is 4/16 or 1/4 inch. Dash numbers
are usually nominal (in name only) and are abbreviations that make ordering of components
easier.
1. Measure the I.D./O.D. diameter with a caliper as shown.
Figure 10.
Hoses and Fittings Measurement.
2. Under the heading MALE THREAD O.D. and FEMALE THREAD I.D., match the measurements with the row in
table to determine proper torque.
