Import Brass Male Nipple Couplings — Buy in wholesale FOB from Supplier in Viet Nam

Minh Hoa Investment Joint Stock Company produces Brass Male Nipple Couplings from Brass Alloy C36000, with a copper range of 58-62%, zinc 35-40%, and lead 1.5-3%. These are straight, short-length threaded fittings with male threads at both ends (or male-female configurations per the broader product range), designed to join two female threaded components in plumbing, HVAC, and gas distribution networks. The C36000 alloy specification aligns with ASTM B16 for free-machining brass rod, enabling precise thread cutting and consistent dimensional repeatability across production lots.

The nipple coupling form factor is defined by its overall length, thread length, and hex or plain body configuration, though specific dimensions for this listing are not provided. In standard practice, brass nipples are manufactured with NPT or BSP threads, with thread engagement lengths calculated to achieve pressure-tight seals without excessive material deformation. The 1.5-3% lead content in C36000 improves machinability but restricts use in potable water systems under lead-free mandates; for such applications, alternative alloys or post-machining surface treatments would be required. The supplier notes capability to manufacture per customer drawings and samples, indicating in-house threading and finishing operations.

Application sectors cited include oil and gas infrastructure, waterworks, and petroleum pipelines, where brass nipples serve as transition or extension pieces in threaded piping systems. The supplier's monthly production capacity is stated at 50,000 pieces, with delivery time dependent on order volume. Minh Hoa operates multiple brand lines (MIHA-XK, MIHA, MBV, MI) and offers customised ball valves and fittings beyond standard catalogue items. Buyers should confirm thread standard, pressure rating, dimensional envelope, and whether the quoted alloy is C36000 or a lead-free alternative for compliance with destination market regulations.

Minh Hoa Investment Joint Stock Company was established in 1993 and is headquartered in Hanoi's Nam Thang Long Industrial Zone, Bac Tu Liem District, with the postal address at B2-4-4 Lot, Thuy Phuong Ward. The company manufactures brass valves and fittings under its own brand portfolio: MIHA-XK, MIHA, MBV, and MI. Its product range extends beyond nipple couplings to include multiple ball valve configurations (male, female, mini, hose-end, gate, check, garden taps) and a broad fittings catalogue (elbow, tee, coupling, quick connect, adapter). The supplier holds a 'harbor' trust tier with a 0.00 response rate and zero recorded average response hours, indicating no recent enquiry response data is available on the platform.

The company states a production capacity of 50,000 pieces monthly and offers factory-standard or export-worthy customised packaging. No ISO certification, factory audit results, specific quality management system, or third-party accreditation is mentioned in the available data. The supplier does not disclose export destinations, major clients, or revenue figures. Buyers should request current business registration, quality system documentation (if any), and evidence of in-process inspection capabilities. The ability to produce per customer drawings suggests engineering and tooling competence, but buyers should validate this through sample evaluation and first-article inspection before committing to volume orders.
