To assist the user in "'reading"
reducing fittings, a variety of
types most commonly required
for piping systems are illus-
trated on this page. In these
illustrations, each opening of
the fitting is identified with a
letter which indicates the se-
quence to be followed in read-
ing the size of the fitting.
In designating the outlets of
reducing fittings, the openings
should be read in the order in-
dicated by the sequence of the
letters "A", "'B", "C", and
"D". On side outlet reducing
fittings, the size of the side
outlet is named last.
Fw exmwdb: A Cross having
one end of the run and one
outlet reduced is designated as:
A B C D
2~ x !~ x 2~ x !~
Simply name the largest open-
ing first and then name the
other openings in the order
indicated,
Although all but one of
the illustrations are of screwed
fittings, the same rules apply to
the "'reading" of reducing
flanged, welding, solder-joint,
and other types of fittings
