The WG9000361401 Pressure Test Connector Assembly is a premium, heavy-duty chassis component engineered specifically for SINOTRUK Howo trucks, allowing technicians to verify air and hydraulic pressure values quickly and accurately. As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM-grade connector assembly as a direct replacement for the original factory unit. The WG9000361401 assembly provides a secure, leak-free test point on the chassis pressure circuit and ensures reliable readings during brake, suspension and air system diagnostics.
Manufactured from high-strength brass and corrosion-resistant steel with a precision-machined thread and a sealed dust cap, the WG9000361401 Pressure Test Connector Assembly is built to exact OEM dimensions. Its robust construction resists vibration, pressure pulses and temperature extremes, delivering dependable service under the constant use and heavy loads of commercial truck operation.
OEM WG9000361401 • Leak-free sealing • Brass and steel body • Vibration resistant • Direct OEM fit
The WG9000361401 Pressure Test Connector Assembly is a critical service component in the chassis system of SINOTRUK Howo trucks. It provides a dedicated, sealed test port where a pressure gauge can be connected to check the operating pressure of the air brake circuit, the air suspension circuit or other pressurized chassis lines.
This WG9000361401 assembly is precision-machined to exact OEM dimensions. The body is produced from high-grade brass with a corrosion-resistant finish, the internal seal is rated for continuous pressure service, and the protective cap keeps dust and moisture away from the test port when it is not in use.
Common signs that a pressure test connector assembly needs replacement include a visible leak at the test point, a cracked or stripped thread, a missing or perished dust cap, and unstable or inaccurate gauge readings during system diagnosis. Fitting a new WG9000361401 unit restores a reliable test point and correct system sealing.
Whether you are repairing a leaking chassis test port, replacing a damaged connector or carrying out preventive maintenance on a fleet of Howo trucks, the WG9000361401 Pressure Test Connector Assembly delivers the quality, reliability and durability that SINOTRUK Howo professionals expect.
The WG9000361401 Pressure Test Connector Assembly is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it threads into the factory test point and seals against the original sealing surface without modification.
This connector assembly is essential in workshops and service fleets where accurate pressure diagnosis is required, such as long-haul transport, construction, mining and municipal service. In these duties, the connector must hold pressure without leaking and allow repeated gauge connections without thread damage.
When replacing the test connector, it is recommended to inspect the surrounding air lines, valve fittings and sealing washers for wear or damage. The WG9000361401 is designed to work with the factory chassis components, ensuring correct sealing and reliable pressure readings during brake and air system checks.
For fleets with multiple HOWO trucks, standardising on the WG9000361401 Pressure Test Connector Assembly simplifies service tooling and ensures the correct test point is available for scheduled maintenance or emergency repairs.
Replacing the WG9000361401 Pressure Test Connector Assembly is a simple procedure that requires basic hand tools and an understanding of the air system. This work should be performed by a qualified technician. Begin by parking the vehicle safely and releasing air pressure from the relevant circuit.
Locate the pressure test connector on the chassis. Remove the protective cap and unscrew the old connector with a suitable wrench, taking care not to damage the surrounding pipework. Inspect the sealing washer and the thread in the port for corrosion or damage.
Fit the new WG9000361401 connector with a fresh sealing washer and tighten it to the correct torque. Refit the protective cap. Pressurise the system and check for leaks at the test point using a soap solution or leak detector. Confirm that a gauge can be connected and that it reads a stable value.
For ongoing maintenance, periodically check that the cap is in place and that the connector is free from dirt or moisture. If a leak develops, inspect the sealing washer before replacing the connector again. Keeping the test point clean and properly capped ensures long-term reliability.
The WG9000361401 Pressure Test Connector Assembly is manufactured in an ISO 9001-certified facility using precision machining and controlled assembly processes. Raw materials are sourced from certified suppliers and undergo incoming inspection for dimensions, material grade and surface finish.
Each connector is machined to exact OEM thread dimensions and then tested for sealing performance under pressure. The dust cap is checked for correct fit, and the sealing washer is inspected for elasticity and thickness. Every unit is subjected to a functional pressure test before packing.
Random samples from each production batch undergo environmental testing, including salt spray, thermal cycling and vibration, to validate long-term reliability in heavy-duty truck applications. These tests ensure the connector continues to perform in the harsh conditions experienced by SINOTRUK Howo vehicles.
We back the WG9000361401 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every pressure test connector assembly delivers the same fit, function and durability as the original factory component.
The WG9000361401 Pressure Test Connector Assembly is a small but vital component for maintaining accurate chassis diagnostics and reliable system sealing on your Howo truck. A leaking or damaged test connector causes pressure loss, false gauge readings and unnecessary diagnostic confusion.
Manufactured from high-quality brass with a precision thread and a protective dust cap, the WG9000361401 offers outstanding reliability, corrosion resistance and long-term durability. Its direct-fit design ensures straightforward installation and immediate compatibility with the factory chassis.
Fleet operators benefit from faster diagnostics, reduced air system downtime and lower maintenance costs. Owner-operators gain peace of mind knowing their pressure checks are accurate and their chassis is sealed to OEM standards, backed by a comprehensive warranty.
