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.

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.

| History: |
From Auto Parts Trading to Manufacturing — Because We Wanted Better Control Over Quality LTHJT did not start as a large manufacturer. We started with a small team of just 7 people, working in the automotive aftermarket and learning the business one customer, one product and one order at a time. As our business grew, we developed into an 80-person auto parts trading company, specializing in replacement parts for a wide range of Japanese and European vehicles. Our product experience expanded from Japanese applications such as Toyota, Honda and Nissan to European vehicles including Mercedes-Benz, BMW, Volkswagen and Audi. Over the years, we built extensive experience in multi-brand auto parts sourcing and learned what professional importers, wholesalers and distributors really expect from their suppliers. But growth also exposed a problem. Many of the products we sourced from external factories could not consistently meet either our quality expectations or the requirements of our customers. For us, simply changing suppliers again and again was not a long-term solution. We wanted greater control over the materials, production processes, product development and final quality. So we made an important decision: Instead of only sourcing products, we would manufacture the products ourselves. With an investment of approximately RMB 200 million, we expanded from auto parts trading into manufacturing and built our own production operation, which has grown to a manufacturing team of approximately 160 people. Today, our manufacturing focus is automotive hoses and rubber components. From rubber raw-material preparation and compound mixing to extrusion, molding, vulcanization, assembly, inspection and finished products, we have brought critical manufacturing processes under our own production and quality-control system. This transition changed more than our production capability. Our years as an auto parts trading company taught us something that pure manufacturing experience alone cannot teach: we understand the product from the buyer's side. We understand why correct fitment matters. We understand why stable batch quality matters. We understand how one defective product can become an after-sales problem for a distributor. And we understand that professional buyers need more than a low price — they need products they can confidently sell to their own customers. That is why our goal has never been simply to manufacture another low-cost aftermarket product. We wanted to manufacture automotive rubber products that could meet the standards we had expected from our own suppliers for years. As our manufacturing capabilities developed, LTHJT automotive hose and rubber products gradually gained recognition from customers for their quality, consistency and practical performance, giving us greater confidence to continue investing in manufacturing, engineering and product development. Our journey can be summarized in three stages: 7-Person Team → 80-Person Auto Parts Trading Company → 160-Person Manufacturing Team But for us, these numbers are not the most important part of the story. Trading taught us what customers need. Today, LTHJT combines two strengths: Focused Automotive Hose Manufacturing + Multi-brand Auto Parts Supply We continue to serve customers requiring Japanese, European and other multi-brand replacement parts, while using our own manufacturing capability to develop and produce automotive hoses and rubber components with greater control over materials, processes and quality. We grew from selling parts to understanding parts — and from understanding parts to manufacturing better ones. Our next goal is not simply to become a bigger factory. It is to become a more reliable long-term partner for our customers: helping them develop better products, reduce sourcing and after-sales risks, and build a stronger automotive parts business. |

At LTHJT, we do more than manufacture and supply auto parts — we help customers develop products, simplify sourcing and reduce purchasing risk. As an automotive hose manufacturer and multi-brand auto parts supplier, we provide integrated services for importers, wholesalers, distributors and aftermarket brands worldwide. Our manufacturing capabilities support automotive coolant hoses, radiator hoses, fuel hoses, turbo and intercooler hoses and other automotive fluid hose applications, while our broader supply network allows customers to consolidate additional multi-brand replacement auto parts through one supplier. If you are developing a new product, simply send us an OEM number, OE sample, drawing, product photo or application requirement. Our team can support product analysis, material selection, tooling, prototyping, testing and mass production. We also provide OEM/ODM manufacturing, private labeling, customized packaging, exclusive product development and, for qualified partners, regional or product-specific distribution cooperation. Our service continues after production. Applicable products can be supported by a warranty of up to 3 years. If a verified product-quality problem or incorrect shipment is caused by us, we will take responsibility and provide an appropriate solution, which may include replacement, return, replenishment or compensation according to the agreed terms. For eligible orders, we can also provide free delivery to designated freight forwarders or warehouses within China, making purchasing and cargo consolidation easier for overseas customers. Whether you need one hard-to-find automotive hose, a new custom-developed product, your own private-label product line, or a large multi-brand OEM purchasing list, you can send us your requirements. We don't want to simply send you a price. We want to understand what you are trying to source, develop or solve — and help you find a more reliable solution. |
