The line features a durable steel tubing with flexible hose sections, fitted with corrosion-resistant end fittings, providing leak-free performance, consistent hydraulic pressure transfer, and exceptional longevity under the continuous vibration, temperature fluctuations, and harsh underbody conditions typical of heavy-duty trucking.
This fluid line (OEM WG9719230088) is critical for maintaining smooth and precise clutch engagement and disengagement, reducing driver fatigue and protecting the transmission from shock loading. Its optimized routing and protective sheathing prevent abrasion and kinking, ensuring uninterrupted fluid flow. The WG9719230088 is built to endure the rigors of long-haul transport, off-road operations, and severe environmental exposure, delivering dependable service over thousands of miles.
OEM direct replacement • Steel tubing with flexible sections • Corrosion-resistant fittings • Precision hydraulic transfer
The WG9719230088 Fluid Line is a complete hydraulic pipe assembly that serves as the critical link between the clutch master cylinder and the slave cylinder in SINOTRUK Howo trucks. Engineered as a direct OEM replacement, this line guarantees correct hydraulic pressure transmission, leak-free connections, and reliable clutch operation. Manufactured to the original equipment specifications, it ensures a seamless fit and consistent performance.
The assembly is constructed from high-quality seamless steel tubing with a protective anti-corrosion coating, combined with reinforced flexible rubber hose sections that absorb vibration and accommodate relative movement between chassis and driveline. The end fittings are precision-machined from brass or zinc-plated steel, featuring double-flare or O-ring sealing designs to prevent fluid leakage. The line is pre-formed to match the original routing, simplifying installation and ensuring proper clearance from hot or moving components.
This fluid line is essential for maintaining the hydraulic clutch system’s integrity, ensuring smooth gear changes and reducing driveline shock. Its robust construction and precise engineering guarantee reliable performance over extended service intervals, meeting the rigorous demands of heavy-duty trucking. It is the direct replacement you can trust to keep your SINOTRUK Howo’s clutch system operating flawlessly.
The WG9719230088 Fluid Line is specifically designed for SINOTRUK Howo heavy-duty trucks, including Howo A7, T7H, T5G, and other models that use this clutch hydraulic line configuration. It is compatible with the standard master cylinder and slave cylinder ports, making it the ideal replacement for restoring clutch feel and performance.
This line is suitable for a wide range of applications, including long-haul trucking, regional distribution, construction, mining, and agricultural operations. The robust construction and leak-proof sealing ensure reliable clutch operation even under sustained heavy loads and frequent shifting cycles.
When replacing, always verify the fitting sizes and overall length to ensure a perfect match. The WG9719230088 is a direct-fit component that simplifies maintenance and restores original hydraulic performance.
Installing the WG9719230088 Fluid Line requires standard wrenches, flare nut tools, and safety precautions. Begin by elevating the vehicle and locating the clutch master cylinder and slave cylinder. Remove the old line by carefully loosening the fittings, using a backup wrench to prevent twisting. Drain any residual fluid and cap the open ports to prevent contamination.
Position the new line following the original routing, ensuring it is clear of hot exhaust components, sharp edges, and moving parts. Secure the line with original clips or new zip ties. Connect the fittings to the master and slave cylinders, tightening them to the specified torque (typically 15–20 N·m). Do not overtighten, as this can damage the flare or O-ring.
After installation, refill the clutch reservoir with fresh DOT 3 or DOT 4 fluid and bleed the system using the standard two-person or pressure-bleeding method. Start by bleeding at the slave cylinder until a steady stream of fluid free of air bubbles appears. Check for leaks at both connections and verify smooth clutch pedal operation.
Regular maintenance includes periodic inspection of the line for chafing, corrosion, or leaks. Replace the fluid according to the manufacturer’s schedule to prevent internal corrosion. This line is engineered for long life, but proactive care ensures continued clutch reliability.
This fluid line is manufactured in an ISO 9001-certified facility using high-quality steel and rubber materials. The steel tubing is sourced from approved mills and tested for tensile strength and dimensional accuracy. The flexible hose is produced from EPDM compound with a textile braid reinforcement, tested for burst pressure and heat aging.
Each assembly undergoes 100% pressure testing (up to 1.5× working pressure) and leak detection. The end fittings are inspected for thread accuracy and sealing geometry. Random samples are subjected to corrosion testing (salt spray) and vibration cycling to validate long-term durability. The line is also checked for correct length and routing shape.
Our commitment to quality ensures a fluid line that delivers leak-free, consistent hydraulic pressure, providing smooth clutch operation and reducing driveline wear. Backed by a comprehensive warranty, this line offers peace of mind for fleet operators and owner-operators.
