The WG9000361208 combined right angle joint assembly is a versatile solution for complex fluid routing in heavy‑duty trucks. Its right‑angle design allows a 90° turn in the line while maintaining a straight‑through flow path for the main line, all in a single, compact assembly. This is particularly valuable in air brake systems, where it redirects supply lines around chassis components, and in air suspension systems, where it routes air to leveling valves. The combination of a push‑in NW9 port (9 mm) and a threaded 12 mm port offers flexibility for connecting both flexible hoses and rigid metal lines. By using the genuine WG9000361208, you achieve a neat, organised installation with minimal pressure loss, zero leakage, and maximum system integrity – directly translating to lower maintenance costs and increased vehicle uptime.

The WG9000361208 combined right angle joint assembly is widely used across the HOWO and Sitrak model ranges, particularly in air brake, air suspension, and cooling systems where directional changes are required. Its combined design with a push‑in and a threaded port makes it ideal for:
The WG9000361208 combined right angle joint assembly 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 paths are smoothly contoured to reduce turbulence and pressure drop, and the right‑angle geometry is optimised for minimal flow restriction. Each assembly 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 assembly tested for leakage at rated pressure – reliability guaranteed.
Proper installation of the WG9000361208 combined right angle joint assembly ensures optimal sealing and performance. For the push‑in NW9 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 threaded 12 mm port (M12x1.5), clean threads thoroughly and apply a suitable sealant (PTFE tape or anaerobic liquid) to the male threads. Hand‑tighten the fitting into the port, then use a wrench to tighten to the recommended torque (20‑25 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 assembly is in a high‑vibration zone, consider using a thread‑locking compound on the threaded port after verifying orientation. Periodically inspect for corrosion or thread wear to maintain long‑term reliability.
Selecting the WG9000361208 genuine combined right angle joint assembly directly impacts the safety and reliability of your HOWO or Sitrak truck’s pneumatic and hydraulic systems. Inferior fittings can lead to leaks, pressure drops, and contamination – all of which compromise brake performance, suspension stability, 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 assembly 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 WG9000361208 right‑angle assemblies for all our air brake and suspension repairs. The combined port design gives us the flexibility we need, and the quality is exceptional – zero leaks since we switched. This is the only assembly we trust for our fleet.”
The WG9000361208 combined right angle joint assembly 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 fitting used in air brake, air suspension, cooling, and fuel systems across these vehicle families. The NW9 push‑in port accepts 9 mm nylon or polyurethane hoses, while the M12x1.5 threaded port is compatible with standard metric fittings. Always verify the OEM number WG9000361208 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 WG9000361208 combined right angle joint assembly 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 right‑angle geometry ensures minimal flow restriction and stable pressure distribution. This assembly 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.
