Yuyao Tonghui Metal Conduit Part Factory, operating as Tonghui, is a privately-held Chinese manufacturer of hydraulic fittings founded in 1989 and headquartered in Yuyao City, Zhejiang Province. The company produces four core product lines — hydraulic adapters, hydraulic plugs, hydraulic bulkheads, and hydraulic tees — manufactured primarily in carbon steel with eco-friendly galvanized surface treatment and stainless steel variants (grades 304, 316, 316L). Thread specifications cover NPT, BSP, JIC, UNF, and metric standards, with custom OEM manufacturing capability based on customer drawings and free sample provision.
The business operates a factory-direct B2B model targeting industrial machinery manufacturers, hydraulic equipment distributors, heavy equipment OEMs, and fluid power system integrators. Tonghui began export operations in 2010, primarily serving European and United States markets, and maintains a 12-language international website as its principal marketing and lead-generation channel. Pricing is quote-based, varying by material grade, thread specification, and order volume, with no publicly disclosed price list.
The company self-reports 300+ technical personnel and 152 industry awards, with corrosion testing capability of 48-96 hours on stainless products and salt-spray testing on galvanized products serving as primary quality differentiators.
