Throughout the entire manufacturing process of
WARD unions, special emphasis is placed upon
the control and accuracy of each operation.
WARD unions are made from closely grained, high

are combined to produce castings that are smooth
and clean in every respect and free from
imperfection.
WARD unions are manufactured in strict
accordance with the requirements for threaded
