Import Brass Unions — Buy in wholesale FOB from Supplier in India

Kalyan Steel Centre supplies brass unions machined from CuZn alloy in C360 or C385 grade, two of the most common free-machining brasses used for threaded pipe fittings. The source data confirms BSP thread conformance and a size spread from 1/4 inch to 4 inches, making these unions suitable for plumbing, HVAC, and industrial fluid distribution networks. The 7412.20 HS code classification indicates standard brass pipe or tube fittings for cross-border trade.

C360 brass, also known as free-cutting or engraving brass, typically contains approximately 61.5% copper and 35.5% zinc with a small lead addition for machinability; C385, or architectural bronze, carries a similar copper content with slightly different zinc balance and is often chosen for decorative or architectural fittings. Both grades offer thermal conductivity around 115-120 W/m·K and good resistance to dezincification in potable water. The threaded form conforms to BSP (British Standard Pipe) parallel or tapered threads, with NPT also referenced for North American compatibility. Standard industry tolerances for brass union threads are typically within ±0.05 mm for diameters up to 1 inch, tightening to ±0.03 mm for precision applications.

Buyers span residential plumbing distributors, commercial HVAC contractors, and industrial maintenance procurement teams across North America, Europe, and Southeast Asia. The supplier notes carton or pallet packaging for containerized export. Trade terms of FOB and CIF are referenced in the source, though buyers should confirm current Incoterms, available certifications, and exact lead times directly with Kalyan Steel Centre before placing an order.

Kalyan Steel Centre operates from Charni Road, Panjrapole, 1st Lane, Mumbai 400004, Maharashtra, India. The supplier carries a harbor trust tier classification and shows a response rate of 0.00% with an average response time of zero hours, which suggests either a newly registered profile or limited platform engagement rather than active rejection of enquiries. Buyers should treat this as a signal to request direct contact verification before relying on platform messaging alone.

The listing presents brass unions as a standard hardware commodity with no unique proprietary technology claimed. The supplier does not state factory ownership, ISO certification, annual output, or client references in the available data. What is offered is a defined material specification (C360/C385), thread standard (BSP/NPT), and size range, which provides enough baseline for technical comparison. Buyers should independently verify the supplier's actual stockholding, inspection capabilities, and whether they operate as manufacturer, stockist, or trader before committing to volume orders.
