LTHJT combines focused automotive hose manufacturing with practical multi-brand auto parts supply.

Our manufacturing business specializes in automotive fluid and thermal-management hose applications, including radiator and coolant hoses, fuel hoses, turbo and intercooler hoses, vacuum brake hoses, transmission oil cooler hoses and custom-developed hose products.

Backed by the automotive parts experience of Tonghua Group since 2008, our Qinghe manufacturing facility began operation in 2024. The facility covers approximately 10,000 square meters and is supported by a team of more than 140 employees.

For custom projects, our engineering team can work from OE samples, drawings and application requirements. We support product analysis, tooling, prototyping, testing and mass production, helping customers turn new product ideas into production-ready solutions.

Beyond the products we manufacture, LTHJT also supplies a broad range of replacement auto parts for Japanese, Korean, European, American and Chinese vehicle applications.

This combination gives our customers two capabilities through one partner: focused hose manufacturing and flexible multi-brand parts sourcing.

We serve auto parts importers, wholesalers, distributors, aftermarket brands and professional buyers worldwide.

Whether you are developing a new hose, sourcing an existing OEM replacement or consolidating a mixed purchasing list, our goal is the same: reduce sourcing complexity, improve communication and build a more dependable supply chain.

At LTHJT, we don't just sell parts. We help you solve sourcing problems.
