从China供应商批发进口3000psi Sae Flange Fitting — FOB条款

The 30000PSI SAE Flange Fitting is a high-pressure hydraulic connector rated for 3000 pounds per square inch working pressure, manufactured by Tianjin Hengyong Hydraulic Technology Co., Ltd. in Tianjin, China. It conforms to SAE J518 and ISO 6162 standards, with normal flange sizes ranging from 1/2 inch to 2-1/2 inch. The fitting is produced in carbon steel as standard, with stainless steel 304/316 and brass available as alternative materials. Surface treatments include smooth finish, zinc plating, or customised options to suit corrosive environments. The ferrule construction is designed for crimping onto hydraulic hose assemblies, forming a permanent, leak-resistant connection in fluid power systems.

Material selection depends on the application environment: carbon steel offers strength and cost efficiency for general industrial use, stainless steel 304 provides good corrosion resistance for moderately aggressive media, and 316 grade suits marine or chemical exposure. Brass serves specialised applications requiring non-sparking or compatibility with certain fluids. Zinc plating on carbon steel provides sacrificial corrosion protection typical of hydraulic hardware. The precise dimensional tolerances of SAE J518 ensure interchangeability with split-flange halves, bolts, and O-ring grooves from major manufacturers. Proper ferrule selection matches the hose dash size and fitting thread specification to achieve rated burst pressure.

This flange fitting serves oil and gas extraction equipment, construction machinery, mining vehicles, and agricultural tractors where reliable hose connections face vibration, pressure spikes, and contamination. Importers typically source these fittings in bulk for hydraulic repair shops, OEM assembly lines, and aftermarket distribution. The supplier notes standard international packaging for global logistics, though buyers should confirm specific palletisation, export crate specifications, and Incoterms directly. Response rate data is currently unavailable, so prospective buyers are advised to allow time for quotation or request immediate contact through alternative channels.

Tianjin Hengyong Hydraulic Technology Co., Ltd. is based in Room 636, Junlin Tower, No.1 Boai Road, Hebei District, Tianjin 300010, China. The company operates from this central Tianjin location, a major port and industrial city in northern China with established logistics networks for hydraulic component exports. The supplier's trust tier is classified as harbor, indicating a baseline verification status on the platform. Notably, the response rate is recorded at 0.00 percent with zero average response hours, which suggests either a new listing, a lapse in active management, or technical issues with enquiry tracking. Buyers should factor this into their communication strategy and consider direct outreach or third-party verification before committing to orders.

The supplier's profile focuses on hydraulic hose ferrule fittings in common sizes, with explicit mention of crimping applications for hose assemblies. There is no stated factory ownership, production capacity, number of employees, annual revenue, or client references in the available data. The company does not list specific certifications such as ISO 9001, material test reports, or pressure testing documentation, though these may be available on request. The product range extends beyond the listed flange fitting to include other ferrule types, fittings, and hoses, suggesting a trading or manufacturing operation with broader hydraulic component access. Buyers are advised to request company registration documents, factory audit reports, and sample evaluation before large orders.
