The WG9000361306 T type three way joint body is a fundamental building block in the pneumatic and hydraulic circuits of your HOWO truck. In heavy‑duty vehicles, fluid distribution must be reliable and efficient to ensure proper operation of brakes, suspension, steering, and cooling systems. This T‑joint body allows a single supply line to be split into two branches, or two lines to be combined, providing the flexibility needed for complex routing. Its precision‑machined threads and smooth internal bore minimise pressure loss and turbulence, ensuring that each connected component receives the correct flow and pressure. By installing the genuine WG9000361306 T type three way joint body, you eliminate the risk of cross‑threading, leakage, or restriction that can compromise system performance and safety.

The WG9000361306 T type three way joint body is a versatile connector used extensively in the pneumatic and hydraulic systems of HOWO and Sitrak heavy‑duty trucks. It is commonly found in air brake circuits, where it distributes compressed air to front and rear brake chambers, as well as in air suspension systems for leveling valves and air springs. This joint body is also used in cooling systems to split coolant flow to different engine or transmission oil coolers, and in fuel return lines for balanced pressure distribution. Its compact T‑shape allows for neat, space‑saving installations, making it a preferred choice for both original equipment and aftermarket repairs. Whether you are troubleshooting a brake system, upgrading air suspension, or performing a cooling system overhaul, this genuine joint body ensures that every connection is secure, leak‑free, and functionally reliable.
The WG9000361306 T type three way joint body is manufactured with a level of precision and quality that sets it apart from generic aftermarket fittings. Starting with high‑grade brass or steel billet, the body is CNC‑machined to exacting tolerances, ensuring that each thread is perfectly formed and each sealing surface is smooth and true. The internal bore is polished to reduce flow resistance and prevent turbulence, while the external surfaces are protected with a durable zinc or nickel plating that resists corrosion, even in salt‑spray environments. Every joint body is pressure‑tested to ensure leak‑free performance under working pressures, and dimensional inspection guarantees that it fits perfectly into the original equipment ports. This commitment to quality means that your pneumatic or hydraulic system will perform reliably, with no unexpected leaks or flow restrictions that could compromise safety or efficiency.
CNC Precision Machining
Threads and sealing faces are machined to micron‑level accuracy for perfect fit and sealing.
Corrosion Protection
Robust zinc or nickel plating provides excellent resistance to rust, moisture, and road salts.
Genuine OEM Quality
Manufactured to Sinotruk’s original specifications – guaranteed fit, form, and function.
100% Pressure Tested
Every joint body is tested for leakage at rated pressure to ensure reliability from day one.
Installing the WG9000361306 T type three way joint body requires careful attention to thread sealing and torque to ensure a leak‑free connection. Always clean the threads of both the joint and the mating ports to remove any debris or old sealant. Apply a suitable thread sealant (e.g., PTFE tape or liquid sealant) to the male threads, taking care not to over‑apply and block the internal bore. Hand‑tighten the joint into each port, then use a wrench to tighten to the recommended torque (typically 15‑20 Nm for M12 brass fittings). Avoid over‑tightening, which can distort the threads or crack the fitting. After installation, pressurise the system and check for leaks using soapy water or a leak‑detection spray. If the joint is part of a high‑vibration area, consider using a locking compound on the threads after verifying correct orientation. Regular visual inspection for corrosion or thread damage will help maintain system integrity.
Choosing the WG9000361306 genuine T type three way joint body is an investment in the safety, reliability, and efficiency of your HOWO or Sitrak truck’s fluid systems. A poor‑quality or mismatched fitting can lead to leaks, pressure drops, and contamination, which in turn can cause brake failure, suspension malfunction, or engine overheating. By using a genuine OEM component that meets Sinotruk’s rigorous standards, you ensure that every connection is strong, leak‑proof, and capable of withstanding the high pressures and temperatures of heavy‑duty operation. Fleet operators and workshop technicians worldwide rely on this joint body to maintain the integrity of their pneumatic and hydraulic circuits, reducing downtime and repair costs. With its proven precision and durability, it is the unequivocal choice for those who refuse to compromise on quality.
“We have standardised on the WG9000361306 T joint body for all air brake repairs in our fleet. The fit and finish are perfect, and we have virtually eliminated leaks from distribution points. This is the quality we expect from genuine HOWO parts.”
The WG9000361306 T type three way 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. Its metric M12 x 1.5 thread size is a common standard, making it compatible with many other commercial vehicle brands that use the same port specification. Always verify the OEM number WG9000361306 on the part or packaging to ensure you are installing the correct joint body for your specific application.
HOWO and Sitrak trucks are exposed to a wide range of extreme conditions – from the freezing cold of northern winter routes to the searing heat of desert highways, from constant vibration to corrosive road salts.
