Products classified under HTS 7307.92.30.30
Malleable Alloy Steel Close Sleeve Nipple 1/2-inch
Short-length threaded sleeve nipple from manganese-alloy steel for HVAC close couplings. Under HTS 7307.92.3030 as compact alloy (non-stainless) threaded sleeves for tight space connections.
Alloy Steel Swage Nipple Sleeve 2-1/2 inch Long
Forged alloy steel threaded swage sleeve with tapered ends for pressure piping transitions. HTS 7307.92.3030 for non-stainless alloy threaded sleeves, despite swage design, as primary function is coupling.
A694 F52 High-Yield Alloy Coupling 8-inch
High-strength A694 F52 alloy steel threaded sleeve for offshore platform risers. Classified HTS 7307.92.3030 for high-yield non-stainless alloy threaded couplings.
Threaded Alloy Steel Barrel Nipple 4-inch
Long-barrel threaded sleeve nipple from alloy steel for structural piping extensions. HTS 7307.92.3030 applies to extended-length non-stainless alloy threaded sleeves.
Low-Alloy Steel Hex Sleeve Coupling 3/4-inch
Hexagon-bodied threaded sleeve from low-alloy steel for easy wrenching in mechanical systems. Under HTS 7307.92.3030 as alloy non-stainless threaded coupling with grip feature.
A182 F11 Class 2 Alloy Elbow-Sleeve 1-1/4 inch
Short-radius alloy F11 threaded combination elbow-sleeve for compact turns. HTS 7307.92.3030 if primarily sleeve function, but check angularity.
Nickel-Alloy Steel Threaded Adapter Sleeve 5-inch
Inconel-like nickel-alloy threaded sleeve for chemical processing. Non-stainless alloy under HTS 7307.92.3030.
Heavy Wall Alloy Steel Coupling Sleeve 10-inch
Sch 160 heavy wall threaded sleeve for high-pressure alloy applications. HTS 7307.92.3030 for thick-walled non-stainless fittings.
Machined Alloy Steel Precision Sleeve 1/4-inch
CNC-machined small-bore alloy threaded sleeve for instrumentation tubing. Fits HTS 7307.92.3030 despite size, as functional pipe coupling.
Forged Alloy Steel Pipe Coupling 2-inch NPT
A threaded sleeve coupling made from low-alloy steel like AISI 4140, designed to join two 2-inch nominal pipe size threaded pipes end-to-end. It falls under HTS 7307.92.3030 as a threaded sleeve of alloy steel (not stainless), used in high-pressure plumbing and industrial piping systems. The alloy composition provides enhanced strength and corrosion resistance compared to carbon steel.
