Products classified under HTS 7307.19.90.40
Grooved Ductile Iron Adapter 4x2-inch
Cast ductile iron adapter with 4-inch to 2-inch grooved ends for system transitions. Under HTS 7307.19.90.40 as other grooved fittings. Enables connection between differing pipe sizes.
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.
Grooved Ductile Iron Elbow 4-inch 90-degree
A 90-degree elbow fitting made of ductile iron with grooved ends for 4-inch piping, commonly used in HVAC and water supply systems. Classified under HTS 7307.19.90.40 for other cast iron/steel grooved-end fittings excluding socket-weld types. The grooves enable roll-grooving installation for leak-proof joints.
Grooved Steel Tee Fitting 3-inch
Cast steel tee connector with grooved ends for 3-inch pipes, used in branching fire mains or industrial piping. It qualifies under HTS 7307.19.90.40 as other grooved-end cast fittings of iron or steel. Provides flexibility in system design with mechanical groove engagement.
Grooved Iron Reducer Coupling 6x4-inch
A cast iron reducer coupling transitioning from 6-inch to 4-inch grooved pipes, essential for diameter changes in water distribution. Falls under HTS 7307.19.90.40 for other grooved-end cast fittings. Facilitates efficient flow transitions without custom fabrication.
Grooved Steel Cross Fitting 2.5-inch
Four-way cast steel cross fitting with grooved ends for 2.5-inch pipes, used in complex fire suppression networks. Classified in HTS 7307.19.90.40 as other grooved couplings and fittings of cast iron/steel. Enables multi-directional piping layouts.
Grooved Ductile Iron Cap 5-inch
Cast ductile iron end cap with grooved connection for 5-inch pipes, used to terminate lines in plumbing systems. Under HTS 7307.19.90.40 for other grooved-end cast fittings. Provides secure, pressure-tight closure.
Grooved Steel Union Fitting 1.5-inch
Cast steel union with grooved ends for 1.5-inch pipes, allowing easy disconnection in maintenance-heavy systems. HTS 7307.19.90.40 covers such other grooved couplings. Ideal for serviceable joints in fire protection.
Grooved Iron Mechanical Coupling 8-inch
Heavy-duty cast iron mechanical coupling for 8-inch grooved pipes in large water mains. Classified HTS 7307.19.90.40 as grooved-end fittings including couplings. Designed for high-pressure, rigid joints.
Grooved Steel 45-degree Elbow 3-inch
45-degree cast steel elbow with grooved ends for 3-inch pipes, optimizing flow direction changes in HVAC ducts. HTS 7307.19.90.40 for other grooved cast fittings. Reduces turbulence compared to 90-degree bends.
