The WG9000361029 joint is a versatile solution for connecting fluid lines in heavy‑duty trucks where higher flow rates and pressures are required. Its hybrid design features an NG8 push‑in port (8 mm) for quick, tool‑free hose connections and an M16x1.5 threaded port for secure attachment to rigid metal lines or adapters. This combination makes it ideal for a wide range of applications, from air brake circuits to fuel and cooling systems, where both flexibility and strength are required. The larger NG8 port allows for higher flow capacity compared to smaller sizes, making it suitable for circuits with greater volume demands. The robust brass construction and precision‑machined threads ensure a tight, vibration‑resistant seal that eliminates leaks and reduces maintenance intervals. By using the genuine WG9000361029, you achieve a reliable, durable connection with minimal pressure loss and maximum system integrity – directly translating to lower operating costs and increased vehicle uptime.

The WG9000361029 joint is widely used across the HOWO and Sitrak model ranges, particularly in systems that require a transition between push‑in hoses and threaded metal lines with larger diameters. Its compact design and hybrid ports make it ideal for:
The WG9000361029 joint is manufactured with uncompromising quality, ensuring it outperforms generic aftermarket alternatives. Made from premium brass billet and CNC‑machined to exacting tolerances, every thread, push‑in bore, and sealing surface is flawlessly formed. The nickel‑plated finish provides a hard, corrosion‑resistant layer that resists rust, chemicals, and road salts, ensuring long‑term durability. The internal flow path is smoothly contoured to reduce turbulence and pressure drop, while the hybrid design offers maximum installation flexibility. Each joint is pressure‑tested to verify leak‑free performance and undergoes dimensional inspection to guarantee perfect fitment in OEM ports. This dedication to quality delivers reliable, maintenance‑free operation, reducing downtime and extending the service life of your vehicle’s fluid systems.
CNC Precision
Threads and sealing faces machined to micron accuracy for perfect sealing and fit.
Corrosion Protection
Nickel plating offers robust resistance to rust, moisture, and harsh chemicals.
Genuine OEM Quality
Built to Sinotruk’s original specifications – guaranteed fit, form, and function.
100% Pressure Tested
Every joint tested for leakage at rated pressure – reliability guaranteed.
Installing the WG9000361029 joint is straightforward, but proper technique ensures a leak‑free, durable connection. For the NG8 push‑in port, cut the hose cleanly and square, then push it firmly into the port until it bottoms out – a tug test should confirm secure retention. For the M16x1.5 threaded port, clean the threads and apply a suitable sealant (PTFE tape or anaerobic liquid) to the male threads of the mating component. Hand‑tighten the joint onto the port, then use a wrench to tighten to the recommended torque (25‑30 Nm). Avoid over‑tightening, which can damage threads or distort the body. After installation, pressurise the system and check for leaks with soapy water. If the joint is in a high‑vibration zone, consider using a thread‑locking compound after verifying correct orientation. Regular inspection for corrosion or thread wear will help maintain long‑term reliability.
Selecting the WG9000361029 genuine joint directly impacts the safety and reliability of your HOWO or Sitrak truck’s pneumatic and hydraulic systems. Inferior connectors can lead to leaks, pressure drops, and contamination – all of which compromise brake performance, fuel efficiency, and engine cooling. By using a genuine OEM component that adheres to Sinotruk’s exacting standards, you guarantee a perfect seal, optimal flow, and long‑term durability. Fleet operators and workshop professionals consistently trust this joint to maintain system integrity, reduce unplanned downtime, and lower overall maintenance expenses. With its proven precision and robust construction, it is the definitive choice for professionals who demand excellence.
“We have standardised on the WG9000361029 joints for all our air brake and fuel line transitions with larger bore requirements. The hybrid design gives us the flexibility we need, and the quality is exceptional – zero leaks since we switched. This is the only joint we trust for our fleet.”
The WG9000361029 joint is designed to fit a broad range of HOWO and Sitrak heavy‑duty trucks, including HOWO‑7, HOWO T series, HOWO A7, Sitrak C7H, T7H, and M5G models. It is a direct replacement for the original connector used in air brake, fuel, and cooling systems across these vehicle families. The NG8 port accepts 8 mm nylon or polyurethane hoses, while the M16x1.5 threaded port is compatible with standard metric fittings, providing higher flow capability. Always verify the OEM number WG9000361029 on the part or packaging to ensure correct application.
HOWO and Sitrak trucks are exposed to the harshest environments – from extreme cold to desert heat, from constant vibration to corrosive road salts. The WG9000361029 joint is engineered to withstand these challenges. Its brass construction and nickel plating resist corrosion and chemical attack, while precision threads and push‑in seals maintain integrity under high pressure and temperature variations. The compact design ensures minimal flow restriction and stable pressure distribution, even with the larger 8 mm port. This joint is built for longevity, providing leak‑free service over the vehicle’s lifetime and reducing the frequency of replacements.
Wide Temperature Range
Reliable from -40°C to +120°C – no loss of sealing or structural integrity.
Vibration Resistant
Robust threads and push‑in grips prevent loosening under constant vehicle vibration.
Corrosion Protection
Nickel plating provides long‑term resistance to moisture, salt, and aggressive chemicals.
High Pressure Capability
Rated for 20 bar pneumatic and 10 bar hydraulic – suitable for most heavy‑duty systems.
The WG9000361029 joint is supplied in protective packaging to ensure safe delivery and convenient storage. Each joint is individually wrapped to prevent thread and bore damage.
