Frequently Asked Questions – Air Reservoir WG9000360714

What is the working pressure rating of this Sinotruk air reservoir?

This air reservoir WG9000360714 is manufactured to handle the standard working pressure specified by Sinotruk for their heavy-duty truck pneumatic systems. It is designed to safely store compressed air at the operating pressures required by the vehicle’s brake and auxiliary circuits. For exact pressure ratings on your specific application, feel free to contact us with your vehicle model details.

Is this air tank a direct fit, or does it require modifications during installation?

Absolutely — this is a direct OEM replacement. The Air Reservoir WG9000360714 matches the original Sinotruk factory dimensions, mounting bracket positions, and port thread specifications. Consequently, it bolts directly onto the chassis without any drilling, welding, or adapter fittings.

How does the seamless steel construction benefit this air reservoir compared to welded tanks?

Seamless steel eliminates longitudinal weld seams, which are typically the weakest points in a pressure vessel. As a result, this air reservoir offers superior resistance to pressure cycling fatigue, reduced risk of stress cracking, and a longer operational lifespan — particularly important for vehicles operating under heavy loads and frequent braking.

Can I order this air reservoir with my own brand label and packaging?

Yes, Mettlead fully supports white-label and custom packaging services. You can supply your brand artwork, and we’ll package the Air Reservoir WG9000360714 under your label. This is especially popular among regional distributors building their own aftermarket parts brand.

How should this air reservoir be maintained to maximize its service life?

To keep this air tank performing optimally, you should regularly drain accumulated moisture from the reservoir through the drain valve, inspect the exterior coating for damage or corrosion spots, and check all port connections for air leaks. Additionally, ensure the upstream air dryer is functioning properly — a failing dryer allows moisture into the tank, which accelerates internal corrosion.

What causes an air reservoir to fail, and when should it be replaced?

Common failure modes include external corrosion perforation (especially in salt-heavy environments), internal rust contamination that clogs downstream valves, damaged port threads causing air leaks, and impact damage from road debris. If you notice slow pressure build-up, audible air leaks near the tank, or visible rust-through, it’s time to replace the reservoir immediately to maintain safe braking performance.
