Products classified under HTS 7412.20.00.65
Forged Brass Nipple 3/4 Inch High Pressure
Forged 3/4-inch brass nipple from copper-zinc alloy, rated 1000 PSI for hydraulic connections. Threaded design places it under HTS 7412.20.00.65 as copper alloy pipe nipple fitting. Superior strength from forging process.
Brass Nipple with PTFE Coating 1/2 Inch
PTFE-coated 1/2-inch brass nipple for corrosion protection in chemical processing lines. Base copper-zinc alloy threaded fitting under HTS 7412.20.00.65; coating considered surface treatment not changing classification.
Schedule 80 Brass Nipple 1-1/2 Inch
Heavy-duty Schedule 80 wall thickness 1-1/2 inch brass nipple for high-pressure steam lines. Copper-zinc threaded fitting HTS 7412.20.00.65 with extra wall strength.
Brass Threaded Pipe Nipple 1/2 Inch
A 1/2-inch threaded brass pipe nipple made from copper-zinc alloy, used to connect two pipes or transition between male and female threaded fittings in plumbing systems. It falls under HTS 7412.20.00.65 as a threaded copper alloy tube fitting classified specifically as a nipple. The uniform threading on both ends allows secure, leak-proof connections in low to medium pressure applications.
Copper Alloy Close Nipple 3/4 Inch Brass
A short-length (under 6 inches) 3/4-inch brass close nipple with threaded ends, crafted from copper-zinc alloy for tight plumbing connections in residential water lines. Classified under HTS 7412.20.00.65 due to its threaded nipple design as a copper alloy tube fitting. Ideal for space-constrained installations where minimal extension is needed.
1 Inch Threaded Brass Nipple for Gas Lines
A 1-inch diameter threaded nipple made from lead-free brass (copper-zinc alloy) designed for natural gas piping connections in HVAC systems. It qualifies under HTS 7412.20.00.65 as a threaded copper alloy pipe fitting specifically denoted as a nipple. Meets NSF/ANSI 61 standards for potable water and gas safety.
Brass Hexagon Nipple 1-1/4 Inch
1-1/4 inch hexagonal brass nipple with dual male NPT threads, made from copper-zinc base alloy for easy wrench gripping in industrial plumbing. Falls under HTS 7412.20.00.65 as a threaded 'other' copper alloy tube fitting nipple. The hex shape facilitates installation in tight spaces.
Lead-Free Brass Nipple 2 Inch Schedule 40
2-inch Schedule 40 lead-free brass nipple with precision-cut threads from copper-zinc alloy, used in commercial water supply lines. Classified HTS 7412.20.00.65 for its threaded copper alloy nipple construction. Complies with CA Proposition 65 lead restrictions.
Brass Reducing Nipple 1/2 x 3/4 Inch
Threaded brass reducing nipple transitioning from 1/2-inch to 3/4-inch, manufactured from copper-zinc alloy for plumbing transitions. Despite reduction, classified under HTS 7412.20.00.65 as a threaded copper alloy nipple fitting. Provides step-up connection without additional elbows.
Marine Grade Brass Nipple 1 Inch
Corrosion-resistant 1-inch marine-grade brass nipple (admiralty brass alloy) with threaded ends for boat plumbing and bilge systems. HTS 7412.20.00.65 applies as threaded copper alloy tube fitting nipple per zinc-dominant composition. Arsenic-enhanced for seawater resistance.
