Grooved Steel Pipe Coupling 2-inch
A cast steel coupling designed with grooved ends for connecting 2-inch steel pipes in fire sprinkler systems. It falls under HTS 7307.19.90.40 as a grooved-end fitting of iron or steel, specifically for cast fittings that are neither stainless nor socket-weld type. These fittings allow for quick, secure connections using mechanical couplings without welding.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If forged rather than cast
Forged grooved fittings are classified under other fittings of iron or steel, not cast fittings.
If stainless steel construction
Stainless steel versions shift to the stainless steel cast fittings subheading.
If sold as complete valve assembly with grooved ends
If integrated with valves or regulators, it may classify as a valve rather than a simple pipe fitting.
