Our AWWA C153 ductile iron fittings are manufactured and tested in full accordance with ANSI/AWWA C153/A21.53, the American Water Works Association standard for ductile iron compact fittings for water service. Available from 3″ to 24″ (DN80–DN600), they are rated for a minimum working pressure of 350 psi (2,413 kPa), making them suitable for a wide range of municipal and industrial applications.

The compact body design delivers the same pressure capacity and dimensional reliability as full-body fittings under AWWA C110, while weighing approximately 30–40% less. This translates into significant savings in material cost, freight, and on-site handling — with no compromise on strength or service life. Cast from ductile iron conforming to ASTM A536 Grade 65-45-12, our fittings offer outstanding impact resistance and ductility, superior to grey iron in toughness and longevity.

AWWA C153 fittings are engineered for use with ductile iron pipe or pipe of similar outside diameter, conveying potable water, wastewater, and reclaimed water. Each fitting is 100% hydrostatically tested and coated with a durable protective finish to ensure leak-tight performance and decades of dependable service in buried and above-ground installations.
