Import 6pc Quick Coupler — Buy in wholesale FOB from Supplier in China

Taizhou Hongbang Machinery Co., Ltd. manufactures a six-piece quick coupler set at its facility in Jinqing Town, Luqiao County, Taizhou, Zhejiang province. The couplers are built from carbon steel with zinc-nickel plating and incorporate stainless steel 304 seals, a combination selected for corrosion resistance against hydraulic fluids and atmospheric moisture. The set is intended for rapid connection and disconnection in hydraulic and pneumatic circuits, including gear coupling and drivetrain applications. No specific pressure rating, flow coefficient, or port thread standard is stated in the source data.

The carbon steel body with zinc-nickel plating offers a typical salt-spray resistance of 240 to 720 hours in neutral salt fog testing, though the supplier does not quote test results. Stainless steel 304 seals provide compatibility with petroleum-based hydraulic oils, water-glycol mixtures, and some synthetic fluids, but not with all phosphate esters. The quick-connect mechanism typically relies on a poppet valve and locking sleeve arrangement; standard industry designs achieve connection in a single push and disconnection via sleeve retraction. Buyers should confirm whether the set covers one size family or mixed sizes, as this affects inventory and application range.

The primary end users are automotive aftermarket distributors, agricultural machinery servicers, and industrial maintenance operations. The source mentions compatibility with a range of hose sizes, but does not list inner diameters, thread forms, or adapter configurations. No MOQ, price band, or lead time is disclosed. Taizhou is located near Ningbo and Shanghai ports, offering container shipping options to major global destinations. Importers should negotiate directly with Hongbang to confirm pressure ratings, seal compatibility charts, and whether the zinc-nickel plating meets specific OEM corrosion specifications.

Taizhou Hongbang Machinery Co., Ltd. operates from Sunrise Industry Development Zone, Jinqing Town, Luqiao County, Taizhou 318058, Zhejiang, China. The company holds a Harbor trust tier, with a response rate of 0.00 percent and zero recorded average response hours, indicating limited communication history on the platform. The supplier is positioned in a region with dense metalworking and fluid power component manufacturing, but the profile does not disclose year of establishment, workforce, or production floor area.

No certifications, patent holdings, or major client references appear in the source data. The listing does not state whether Hongbang operates as an OEM producer, an ODM designer, or a trade intermediary. Buyers should request a company profile, business licence, and any available factory audit reports before advancing to sample or trial orders. The absence of response metrics suggests that direct outreach through alternative channels may be necessary to establish reliable contact.
