WARD flange components are made with high quality iron
and are designed to handle the tough service that flange
components normally experience. Precision machining
and thread chamfering allow WARD flange components
to be easily installed. Most importantly, quality is built
into the design, material and manufacturing of each of
WARD’s flange components.
Cast Iron flanges may have either a black or galvanized
finish.
