Detail Description

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.

Automotive Hose Production Line & Manufacturing Capability
Description

LTHJT operates an integrated automotive hose manufacturing facility in Qinghe, China, covering key production processes from rubber raw materials to finished automotive hoses and molded components.

Our manufacturing equipment includes 7 automotive hose extrusion lines, 20 vulcanization tanks, 20 high-precision rubber injection molding machines, precision plastic injection molding equipment, and in-house rubber mixing equipment.

Key production processes include rubber mixing, compound preparation, hose extrusion, forming, molding, vulcanization, assembly, dimensional inspection, testing and final product verification.

Our production capabilities support a wide range of automotive hose applications, including radiator hoses, coolant hoses, fuel hoses, turbo and intercooler hoses, vacuum brake hoses, transmission oil cooler hoses and other automotive fluid-transfer hoses.

By controlling critical manufacturing processes in-house, LTHJT can better manage material consistency, dimensions, production stability and batch-to-batch quality.

In addition to standard replacement products, our production lines support OEM and ODM automotive hose manufacturing, small-batch development and customized production for aftermarket brands, importers, wholesalers and professional auto parts buyers.

From rubber raw material to finished automotive hose, we control the processes that matter.

OEM & ODM Automotive Hose Manufacturing

Description

Looking for an automotive hose that is difficult to source, discontinued or unavailable in your market?

LTHJT provides OEM and ODM automotive hose development and manufacturing services for global aftermarket customers.

Customers can send us an OE sample, OEM part number, technical drawing, vehicle application or specific product requirement. Our team can evaluate the application and support the project from initial analysis to production.

Depending on the product, our OEM/ODM development process may include:

OE Sample / Drawing → Product Analysis → Material Selection → Structure Confirmation → Tooling → Prototype → Testing → Production Validation → Mass Production

We support custom development for radiator hoses, coolant hoses, heater hoses, fuel hoses, turbo hoses, intercooler hoses, intake hoses, transmission oil cooler hoses and other molded or extruded automotive rubber hose applications.

Our integrated manufacturing capability allows important processes such as rubber compound preparation, extrusion, molding and vulcanization to be controlled within our production system.

This gives customers a practical solution for developing OEM replacement hoses, aftermarket replacement hoses, private-label products and hard-to-find automotive hose applications.

We don't simply copy a sample and send a price.

We first understand the application, product requirements and problem you are trying to solve — then help turn the requirement into a production-ready automotive hose.

Automotive Hose R&D and Custom Product Development

Description

A reliable automotive hose starts before mass production.

LTHJT's product development capability supports customers who need to reproduce an existing OE hose, develop a discontinued replacement part, improve an existing product or create a new automotive hose for a specific vehicle application.

Our development work can begin from an OE sample, OEM number, technical drawing or customer requirement.

The engineering process may include sample analysis, dimensional measurement, CAD-based product development, material and structure evaluation, tooling development, prototype production, testing and production validation.

For suitable projects, initial samples can be developed in approximately 7–10 days, depending on product structure, tooling, material and testing requirements.

Product verification can include dimensional inspection and applicable performance testing. Available factory testing capabilities include burst-pressure testing, tensile-strength testing, ozone-aging testing and other product inspections according to project requirements.

Our R&D capability works directly with our manufacturing processes, helping shorten the path from:

Customer Requirement → Engineering → Prototype → Testing → Production

This is particularly valuable for aftermarket buyers developing hard-to-find, discontinued or market-specific automotive hose applications.

You bring the application. We help turn it into a manufacturable product.
