Subheadings
Products classified under HTS 7307.99.50
Carbon Steel Cross Fitting
A carbon steel cross fitting connecting four pipes at right angles for distribution manifolds in oil and gas lines. HTS 7307.99.50 covers it as other pipe fittings of iron or steel. High-strength for demanding pressure environments.
Steel Pipe End Cap
Plain steel end cap for sealing pipe extremities in temporary setups or storage. Falls under HTS 7307.99.50 as other tube fittings. Economical solution for protection during transport.
Stainless Steel Bulkhead Fitting
Stainless steel bulkhead fitting for passing pipes through tank walls, used in marine and chemical tanks. HTS 7307.99.50 for other steel fittings. Sealed design prevents leaks.
Galvanized Steel Pipe Bend
Galvanized 45-degree pipe bend for smooth flow direction changes in drainage. Other fitting under HTS 7307.99.50. Durable for outdoor use.
Carbon Steel Pipe Plug
Threaded carbon steel plug for closing pipe openings in pressure systems. HTS 7307.99.50 other category. Square head for wrench use.
Steel Pipe Reducer Bushing
Steel bushing reducing female threads for pipe size adaptation. Other fitting HTS 7307.99.50. Essential for retrofits.
Stainless Steel Pipe Wye Fitting
Y-shaped stainless wye for splitting flows in sanitary systems. HTS 7307.99.50 other. Smooth interior.
Iron Pipe Expansion Joint
Iron bellows-style expansion joint absorbing pipe movement. Other under HTS 7307.99.50. Vibration dampening.
Stainless Steel Threaded Elbow Fitting
A 90-degree elbow fitting made from stainless steel with threaded ends, used to connect pipes at right angles in plumbing and industrial piping systems. It falls under HTS 7307.99.50 as a tube or pipe fitting of iron or steel, specifically in the 'other' category for non-specific flange, threaded, or socket fittings. This classification applies to its general use in fluid conveyance systems.
Galvanized Steel Pipe Coupling
A galvanized steel coupling designed to join two pipes of the same diameter end-to-end in water supply or drainage systems. Classified under HTS 7307.99.50 as an 'other' iron or steel pipe fitting, not covered by more specific threaded or flanged categories. The zinc coating provides corrosion resistance for outdoor applications.
Carbon Steel Reducing Tee Fitting
A carbon steel tee fitting that connects three pipes, reducing from one size to smaller branches, used in HVAC and process piping. It is classified in HTS 7307.99.50 as an other tube or pipe fitting of iron or steel, outside specific categories like flanges. Ideal for branching fluid lines in industrial setups.
Steel Pipe Sleeve Adapter
A steel sleeve adapter used to extend or repair pipe connections by slipping over ends, common in irrigation and structural piping. Falls under HTS 7307.99.50 as an other iron or steel pipe fitting, not specified elsewhere. Provides a simple, non-threaded joining solution.
Black Iron Pipe Cap Fitting
A black iron threaded cap used to seal the end of pipes in gas or water lines, preventing leaks. Classified under HTS 7307.99.50 as other iron or steel fittings, suitable for low-pressure applications. The black oxide finish resists corrosion in dry environments.
Stainless Steel Pipe Union Fitting
A stainless steel union allowing easy disconnection of pipes without cutting, used in maintenance-heavy systems like food processing. Under HTS 7307.99.50 as other steel pipe fittings, beyond threaded specifics. Features a nut and seat for reliable sealing.
Galvanized Steel Pipe Nipple
Short galvanized steel nipple with threads on both ends for close pipe connections in plumbing. Classifies in HTS 7307.99.50 as other fittings when not precisely matching nipple subheadings. Corrosion-resistant for exposed installations.
