WARD Plugs and Bushings are produced in both
Malleable Iron and Cast Iron grades. The iron from
which they are made is held to strict formula by
careful chemical analysis and control.
Tapping is done on the most modern type of
threading machines. Every fitting is hand sorted
and inspected to eliminate defective castings.
Ward plugs and bushings comply with the
standards and specifications seen below.
