The global automotive landscape is undergoing a paradigm shift. While electric vehicles (EVs) dominate headlines, the Internal Combustion Engine (ICE) and Hybrid markets remain the backbone of global logistics and heavy industry. Within these sectors, the efficiency of torque transfer relies heavily on the integrity of the clutch system and the hydraulic fluid (often referred to as Clutch Fluid) that powers it.
Clutch fluid is essentially a specialized hydraulic oil, typically meeting DOT 3, DOT 4, or DOT 5.1 standards. Its primary function is to transmit pressure from the clutch pedal to the clutch master cylinder and finally to the slave cylinder. In the high-stakes environment of international logistics, any degradation in fluid viscosity or thermal stability can lead to catastrophic transmission failure.
Heavy-duty trucks operating in mountainous regions require fluids with a high wet boiling point to prevent "vapor lock," a phenomenon where the fluid boils and creates air bubbles, leading to a "spongy" pedal feel.
Modern clutch systems require consistent viscosity across extreme temperature ranges, from -40°C in Siberian winters to 50°C in Middle Eastern deserts.
Premium clutch fluids must be non-corrosive to the EPDM rubber seals and metallic pistons found in high-performance master cylinders.
Zhejiang TVC Auto Co., Ltd. was established to become an independent, specialized company focused on manufacturing clutch parts. After more than ten years of continuous effort, the company has grown into a significant player in the industry.
Led by renowned experts, researchers, and senior engineers in clutch manufacturing, we take responsibility for technology, quality management, product development, and sales. Our management team, with expertise in manufacturing, production, logistics, procurement, and equipment management, has built three major product lines (light, medium, and heavy) covering a wide range of products.
In the competitive world of automotive exports, China's advantage is no longer just "low cost"—it is Integrated Efficiency. At TVC Auto, we specialize in the research, development, and production of clutches for light, medium, and heavy trucks.
Precision machining for clutch master cylinders ensures micron-level tolerances, reducing fluid leakage and extending component lifespan.
Our workshop houses stamping equipment from 30T to 2000T, allowing for the creation of high-durability clutch covers and pressure plates.
Imported advanced heat treatment equipment ensures that our friction linings and springs can withstand extreme thermal cycles without losing structural integrity.
Automated glass surface assembly and four full-function pressure test lines ensure every unit leaving our factory is "Zero-Defect" ready.

Understanding the interaction between Clutch Fluid and Friction Materials is critical for any global procurement officer. A clutch is essentially a friction-based decoupling device. When the driver presses the pedal, the fluid translates that physical movement into hydraulic pressure.
Our engineering team designs products for specific global environments:
| Component | Material / Tech | Global Requirement |
|---|---|---|
| Master Cylinder | Aluminum/Cast Iron Alloy | High pressure resistance, low leakage |
| Friction Lining | Brass-reinforced Composite | Heat dissipation, low noise, long life |
| Diaphragm Spring | 50CRV4 High-Grade Steel | Consistent clamping force across millions of cycles |
| Release Bearing | Precision Sealed Ball Bearings | Self-aligning, maintenance-free operation |
The industry is moving toward Smart Actuation. We are currently researching electronic clutch actuators (ECAs) which eliminate the need for traditional clutch fluid in certain automated manual transmission (AMT) systems. However, for the aftermarket and the majority of current global fleets, high-performance hydraulic systems remain the standard. Sustainability is another key trend, with a focus on asbestos-free friction materials and recyclable hydraulic components.
TVC Auto has built an extensive network of customers and partners, both locally and internationally. We understand that global buyers need more than just a product; they need a Reliable Partner.
We provide detailed technical data sheets, cross-reference OEM numbers, and compatibility analysis to ensure you order the right part for your specific fleet.
With our strategic location in Zhejiang, we offer rapid shipping to major ports (Ningbo/Shanghai), ensuring your "Just-in-Time" inventory needs are met.
Every product is backed by our quality warranty. If issues arise, our technical team provides swift troubleshooting and replacement services.
