Products classified under HTS 7609.00.00.00
Aluminum Elbow Fitting 90 Degree
A 90-degree elbow fitting made from extruded aluminum alloy, used to connect aluminum pipes at right angles in plumbing and HVAC systems. It falls under HTS 7609.00.00.00 as an aluminum tube or pipe fitting designed for joining pipes. The fitting is typically threaded or weldable for secure connections.
Aluminum Threaded Coupling
A straight aluminum coupling with internal/external threads for joining two aluminum tubes end-to-end in fluid transfer systems. Classified under HTS 7609.00.00.00 as a tube/pipe fitting example like couplings. Commonly used in irrigation and pneumatic applications.
Aluminum Reduction Sleeve
A tapered aluminum sleeve fitting that connects tubes of different diameters in piping systems. It qualifies under HTS 7609.00.00.00 as a sleeve-type tube/pipe fitting. Ideal for transitional sizing in automotive and marine plumbing.
Aluminum Barstock Tee Fitting
A T-shaped fitting forged from aluminum barstock for branching pipe connections in pressure vessels. Falls under HTS 7609.00.00.00 as an aluminum tube/pipe fitting. Used in oil & gas and chemical processing.
Aluminum Compression Union Fitting
A compression-type union fitting made of aluminum for easy disconnection of tube sections without tools. Classified in HTS 7609.00.00.00 as a pipe coupling variant. Common in refrigeration and air conditioning lines.
Aluminum Pipe Cap End Fitting
Threaded or slip-on aluminum cap used to seal the end of aluminum pipes in systems. Under HTS 7609.00.00.00 as a tube/pipe fitting closure. Applied in plumbing termination and pressure testing.
Aluminum Socket Weld Coupling
Socket weld aluminum coupling for high-pressure permanent joints in pipe systems. HTS 7609.00.00.00 covers this as a welded tube fitting. Used in aerospace and cryogenic applications.
Aluminum Flange Adapter Fitting
Aluminum adapter with one flanged end and threaded other for pipe-to-flange transitions. Fits HTS 7609.00.00.00 as a tube/pipe fitting. Essential for pump and valve connections.
Aluminum Bulkhead Union Fitting
Bulkhead union for passing tubes through tank walls with sealed connections. Under HTS 7609.00.00.00 as specialized pipe fitting. Used in marine fuel systems and pressure vessels.
Aluminum Swivel Nut Adapter
