Subheadings
Products classified under HTS 7412.20.00
Brass Compression Elbow Fitting
A 90-degree elbow fitting made from copper-zinc brass alloy used for connecting copper tubing in plumbing systems. It falls under HTS 7412.20.00 as a tube fitting of copper alloys, specifically brass where zinc predominates over other elements. Commonly used in residential water lines.
Brass Threaded Coupling Connector
A straight threaded coupling made from brass (copper-zinc alloy) for joining two pipes end-to-end in hydraulic systems. Classified under HTS 7412.20.00 due to its copper alloy composition and function as a pipe fitting. Ideal for low to medium pressure applications.
Bronze Flange Adapter Fitting
A bronze (copper-tin alloy) adapter with flange ends for connecting pipes to flanged equipment in marine applications. HTS 7412.20.00 applies as it's a copper alloy tube fitting where tin predominates. Corrosion-resistant for saltwater environments.
Bronze Socket Weld Union
Socket weld union fitting made from copper-tin bronze for high-pressure gas lines. Classified HTS 7412.20.00 as copper alloy pipe fittings with tin-base composition. Designed for easy disassembly.
Brass Barb Hose Adapter
Single barb x NPT threaded adapter from brass for connecting rubber hoses to pipes. HTS 7412.20.00 as copper-zinc alloy tube/pipe fittings. Common in automotive cooling systems.
Nickel Silver Compression Nut
Compression nut fitting from nickel silver alloy (Cu-Ni-Zn, Ni≥5%) for 1/4" OD tubing. HTS 7412.20.00 covers all copper alloy tube fittings. Decorative finish for exposed installations.
Brass Cap End Fitting
Threaded brass cap for closing pipe ends in plumbing systems, made from copper-zinc alloy. Falls under HTS 7412.20.00 as copper alloy tube/pipe fittings. Prevents contamination in open systems.
Bronze Cross Fitting
Four-way bronze cross fitting (copper-tin alloy) for multi-line manifold connections. HTS 7412.20.00 for copper alloy pipe fittings. Used in HVAC condensate drainage.
Nickel Silver Reducing Tee Fitting
A reducing tee made from nickel silver (copper-nickel-zinc alloy with Ni ≥5%) for instrumentation tubing. Falls under HTS 7412.20.00 as copper alloy pipe fittings. Provides decorative finish and corrosion resistance.
Brass Push-Fit Sleeve Connector
Push-to-connect sleeve fitting from lead-free brass for potable water PEX tubing. HTS 7412.20.00 covers copper alloy tube fittings; this meets NSF-61 standards. No-tool installation for DIY plumbing.
