Fittings are manufactured of ductile iron, grade 70-50-05 (minimum tensile strength: 70,000 psi; minimum yield strength: 50,000 psi; minimum elongation: 5%) in accordance with AWWA C110 or C153.
All pressure ratings shown are AMERICAN’s suggested standard and are for water service.
“Thrust Collars” are designed to accomodate the force generated by the pipe line operating at the rated working pressure. “Wall Collars”, also called “Water Stops”, are intended to prevent leakage through a wall. The wall collar does not meet the requirements for a thrust collar.
Weights of fittings can vary due to changes in foundry practice.
