Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cast from gray iron instead of ductile
Gray cast iron fittings are excluded from ductile-specific suffixes.
If machined from bar stock (not cast)
Non-cast threaded fittings go to fabricated/other categories.
If for mechanical joint (grooved) ends
Grooved ductile fittings have their own statistical breakout.
