The WG9000361301 L shaped connector is an essential component for efficient fluid routing in the constrained spaces of modern heavy‑duty trucks. Its L‑shape design allows a line to enter and turn 90° while providing an additional branch, all in a single, compact fitting. This is particularly advantageous 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 threaded ports (NG12 and M12x1.5) and a push‑in port (NW12) offers exceptional flexibility, allowing connection to both rigid metal lines and large‑diameter flexible hoses. By choosing the genuine WG9000361301, you achieve a neat, organised installation with minimal pressure loss, zero leakage, and maximum reliability – reducing maintenance costs and vehicle downtime.

The WG9000361301 L shaped three way connector is widely used across the HOWO and Sitrak model ranges, particularly in air brake, air suspension, and cooling systems where a mix of threaded and push‑in connections is required. Its compact L‑shape and mixed port sizes make it ideal for:
The WG9000361301 L shaped connector 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. Internal bores are polished to reduce flow resistance and turbulence, and the L‑shape geometry is optimised to maintain consistent pressure distribution. Each connector 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, bores, 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 connector tested for leakage at rated pressure – reliability guaranteed.
Proper installation of the WG9000361301 L shaped connector ensures optimal sealing and performance. For the push‑in NW12 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 NG12 (M14x1.5) and M12x1.5 ports, clean threads thoroughly and apply a suitable sealant (PTFE tape or anaerobic liquid) to the male threads. Hand‑tighten the fitting into each port, then use a wrench to tighten to the recommended torque (NG12: 25‑30 Nm, M12x1.5: 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 connector is in a high‑vibration zone, consider using a thread‑locking compound on the threaded ports after verifying orientation. Periodically inspect for corrosion or thread wear to maintain long‑term reliability.
Selecting the WG9000361301 genuine L shaped connector 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 connector 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 WG9000361301 L‑connectors for all our air brake and suspension repairs. The mixed port types give us the flexibility we need, and the quality is exceptional – zero leaks since we switched. This is the only connector we trust for our fleet.”
The WG9000361301 L shaped three way connector 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 NG12 (M14x1.5) and M12x1.5 threaded ports are compatible with standard metric fittings, while the NW12 push‑in port accepts 12 mm nylon or polyurethane hoses. Always verify the OEM number WG9000361301 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.
