It is specifically sized for the 206mm diameter tank and includes a rubber cushion to absorb vibration, preventing metal‑on‑metal contact and extending the service life of both the strap and the tank.
This high‑strength socket head cap screw is used to secure various mounting components within the AMT Air Tank assembly. Its cylindrical head and internal hex drive allow for precise torque application, ensuring a reliable and vibration‑proof connection in the demanding under‑chassis environment.
The Tension Pin is a robust cylindrical locking element that secures the fastening strap and other pivoting connections. It is designed to withstand high shear loads and is retained by a cotter pin or spring clip, ensuring the AMT Air Tank remains firmly attached even under severe road conditions.
The Hexagon Flange Nut M14*1.5 is a self‑locking nut with an integrated flange that provides a wide bearing surface, eliminating the need for a separate washer. It is used in conjunction with the M14 bolts to securely fasten the tank bracket and other heavy‑duty components, resisting loosening from vibration.
This precision‑formed steel bracket is specifically designed to support the 8‑litre air tank on the C7H chassis. It features M14 mounting holes with a 50mm spacing, providing a stable platform that distributes the tank’s weight evenly and aligns perfectly with the vehicle’s existing frame holes.
The Hexagon Flange Bolt M14*1.5 is a high‑tensile fastener that mates with the flange nut to create a robust, vibration‑resistant joint. Its flange head distributes clamping pressure over a large area, protecting the bracket and chassis surfaces from deformation.
The Drain Valve is a manual or automatic valve located at the lowest point of the AMT Air Tank, allowing accumulated moisture and contaminants to be purged. Regular draining prevents internal corrosion and ensures that the compressed air supplied to the AMT system remains clean and dry.
The Elastic Element NG12 is a rubber or polymer damping component that isolates the air tank and its fittings from chassis vibration. It also compensates for slight misalignments in the mounting system, reducing stress on connections and prolonging the life of the pneumatic seals.
The Circlip NG12 is a snap‑ring that retains components within a bore or on a shaft. In the AMT Air Tank assembly, it secures the elastic element and other internal parts, ensuring they remain in position without the need for additional fasteners.
The Nut Base NG12 is a threaded insert that provides a strong, wear‑resistant mounting point for pneumatic fittings. It is typically press‑fitted into the tank or bracket, offering a reliable interface for the connection of air lines.
This 90‑degree fitting connects NG12 and NW12 air lines, allowing flexible routing in confined chassis spaces. Its corrosion‑resistant brass or steel construction ensures a tight, leak‑free seal, essential for maintaining system pressure in the AMT Air Tank circuit.
This straight union connector provides an inline connection between two NG12 hoses or tubes. It is commonly used to extend air lines or repair damaged sections, ensuring uninterrupted airflow within the AMT Air Tank system.
The Check Valve is a one‑way device that allows air to flow in only one direction, preventing back‑flow from the AMT Air Tank to the compressor or other circuits. This maintains system pressure and ensures that the AMT gearbox receives an immediate supply of air when needed.
This three‑way connector splits a single air supply into three separate NW9 outlets. It is used to distribute compressed air from the AMT Air Tank to multiple pneumatic consumers, such as the gear actuator, clutch servo, and auxiliary brakes.
This specialised connector combines NW9 and NG12 ports with an additional test point. It allows technicians to attach a pressure gauge or diagnostic tool without interrupting the main circuit, facilitating easy system health checks on the AMT Air Tank.
This angled connector is part of the 232 series, offering a compact 90‑degree turn between NG12 and NW12 ports. Its compact design is ideal for tight spaces around the AMT Air Tank, and its durable construction resists the effects of oil, moisture, and temperature extremes.
The Tension Pin (available in two variants under different part numbers) is a hardened steel pin used to secure the fastening strap and other pivoting joints. Its precise diameter and surface finish ensure a snug fit, preventing play and wear in the mounting system of the AMT Air Tank.
Our AMT Air Tank is manufactured to Sinotruk’s original specifications, using high‑grade aluminium alloy and precision‑formed components. Every bracket, valve, and fitting is designed to match the C7H chassis, ensuring a perfect fit and long‑lasting performance.

The AMT Air Tank is the heart of the pneumatic system that powers the automated manual transmission in the Sitrak C7H. It stores compressed air generated by the vehicle’s compressor, ensuring that there is always sufficient pressure available for rapid gear shifts and clutch actuation.
The 8‑litre aluminium tank is lightweight yet durable, and its corrosion‑resistant properties make it ideal for long‑haul trucks that operate in humid or salty conditions. The tank is designed to meet the stringent pressure requirements of the AMT system, with a working pressure of up to 12 bar.
The fastening strap and bracket assembly provide a secure mounting solution that isolates the tank from chassis vibration, reducing stress on the mounting points and extending the life of the tank. The rubber cushioning elements dampen road shocks, ensuring that the tank remains stable even on rough terrain.
A comprehensive network of fittings – including the check valve, drain valve, and various connector bodies – ensures that the AMT Air Tank integrates seamlessly with the vehicle’s pneumatic circuits. The check valve prevents pressure loss when the compressor is off, while the drain valve allows for easy removal of accumulated moisture.
The use of NG12 and NW12 fittings throughout the system provides standardised connection points, making it easy to replace or upgrade individual components. The T‑type connectors and elbows allow for flexible routing of air lines, accommodating the tight spaces found around the chassis.
