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.

(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.

(3)

To find the sealing surface angle, use a

protractor and measure the sealing surface

parallel to the centerline of the fitting.
