The WG9000361206 right angle joint body is a fundamental component for efficient fluid routing in the constrained spaces of modern heavy‑duty trucks. Its 90° design allows a sharp directional change without the need for multiple fittings, reducing potential leak points and simplifying installation. This is particularly valuable in air brake systems, where it redirects supply lines around chassis rails, and in air suspension systems, where it routes air to leveling valves and air springs. With two NW9 push‑in ports, this joint accepts 9 mm hoses, providing a secure, vibration‑resistant connection that stays tight even under high pressure and constant movement. By using the genuine WG9000361206, you achieve a compact, organised installation with minimal pressure loss, zero leakage, and maximum system integrity – directly translating to lower maintenance costs and increased vehicle uptime.

The WG9000361206 right angle joint body 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 compact design with two NW9 push‑in ports makes it ideal for:
The WG9000361206 right angle joint body is manufactured with uncompromising quality, ensuring it outperforms generic aftermarket alternatives. Made from premium brass billet and CNC‑machined to exacting tolerances, every 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, and the right‑angle geometry is optimised for minimal flow restriction. Each joint body 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
Push‑in 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 joint body tested for leakage at rated pressure – reliability guaranteed.
Proper installation of the WG9000361206 right angle joint body ensures optimal sealing and performance. For each 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. Ensure the hose is fully inserted and that the retaining ring locks into place. No additional sealant or tools are required for the push‑in connection. After installation, pressurise the system and check for leaks with soapy water. If the joint body is in a high‑vibration zone, periodically inspect the hose insertion to ensure it remains fully seated. Regular inspection for corrosion or damage will help maintain long‑term reliability.
Selecting the WG9000361206 genuine right angle joint body 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 joint body 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 WG9000361206 right‑angle joints for all our air brake and suspension repairs. The push‑in design makes installation quick and reliable, and the quality is outstanding – zero leaks since we switched. This is the only joint we trust for our fleet.”
The WG9000361206 right angle joint body 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 ports accept 9 mm nylon or polyurethane hoses, which are standard in many commercial vehicle applications. Always verify the OEM number WG9000361206 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 WG9000361206 right angle joint body is engineered to withstand these challenges. Its brass construction and nickel plating resist corrosion and chemical attack, while the push‑in sealing mechanism maintains a secure grip on the hose under high pressure and temperature variations. The right‑angle geometry ensures minimal flow restriction and stable pressure distribution. This joint body 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
Push‑in retaining rings maintain a tight grip, preventing hose disconnection 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 WG9000361206 right angle joint body is supplied in protective packaging to ensure safe delivery and convenient storage.
