Import Aluminum Camlock Coupling — Buy in Bulk from Supplier in China

The aluminum camlock coupling from Ningbo Haga Industries Co., Ltd is a quick-connect hose fitting manufactured from industrial-grade aluminum alloy, designed for rapid assembly and disassembly in fluid transfer systems. The coupling employs a cam and groove mechanism where lever arms on the female half engage lugs on the male adapter, creating a mechanical seal without threaded engagement. Standard sizes range from 1/2 inch to 8 inch nominal bore, with working pressure ratings typically from 50 to 250 psi depending on size and material grade. The aluminum construction offers a density of approximately 2.7 g/cm³, yielding significant weight reduction compared to equivalent stainless steel or brass counterparts while maintaining adequate structural integrity for general-purpose applications.

Material specification for this coupling category typically utilizes ASTM B26 cast aluminum alloy or extruded 6061-T6 aluminum, with surface treatments including natural finish, anodized coating, or chromate conversion for enhanced corrosion resistance. The sealing interface relies on a replaceable nitrile rubber (NBR), EPDM, or Viton gasket selected for chemical compatibility with the conveyed medium. Thread configurations commonly include NPT, BSPP, and BSPT standards, with hose shank, flanged, or welded end connections available to suit system architecture. Precision casting or CNC machining ensures dimensional tolerances of ±0.25 mm on critical sealing diameters, with cam lever operation requiring typically 15-25 N of manual force to achieve full engagement. Quality verification includes pressure testing to 1.5 times working pressure and vacuum testing for suction applications.

Primary application sectors include agricultural irrigation and spraying equipment, construction dewatering and concrete pumping, chemical transfer and batching systems, petroleum product handling, and water treatment facilities. Buyers typically specify camlock couplings where frequent hose changeover occurs or where tool-free connection is operationally critical. Sourcing from Ningbo Haga Industries requires confirmation of exact alloy grade, gasket material specification, and thread standard to ensure system compatibility. The supplier's location in Ningbo, Zhejiang Province provides access to established port infrastructure, though response rate data indicates zero recorded engagement, suggesting direct outreach may be necessary to establish communication channels and confirm current production capacity, minimum order quantities, and available Incoterms.

Ningbo Haga Industries Co., Ltd is located at No. 1 Youngor Avenue, Ningbo 315000, Zhejiang Province, China, positioning the company within the Yangtze River Delta manufacturing corridor with access to Ningbo-Zhoushan Port, one of the world's largest cargo handling facilities. The supplier carries an 'imported' tier designation and 'harbor' trust classification, though the response rate stands at 0.00 percent with zero average response hours recorded, indicating no verified buyer engagement through the platform's tracking systems. The company profile does not disclose establishment year, factory square footage, employee count, annual revenue, or specific certifications held, so no operational scale can be assumed beyond the registered address and product listing activity.

The listing presents aluminum camlock couplings as the core product offering, emphasizing quick-connect functionality for fluid transfer across agriculture, construction, and chemical processing sectors. The source description claims international certifications and compliance with safety and quality standards, but no certifying body, standard number, or certificate validity period is named, so buyers must independently verify any claimed accreditation. Payment terms mentioned include Letter of Credit (L/C) and Telegraphic Transfer (T/T), with FOB and CIF shipping terms referenced, though these require direct confirmation with the supplier as binding terms. The profile does not indicate whether Ningbo Haga Industries manufactures these couplings directly or operates as a trading intermediary, nor does it list OEM/ODM capabilities, existing client references, or export market experience.
