• Superior Corrosion Resistance: The electrostatic powder-coated finish provides long-lasting protection against road salt, moisture, and debris, preventing rust and extending service life in harsh undercarriage environments.

• Precision Sealing: Machined threaded ports with high-quality gaskets ensure leak-free connections, making it a reliable replacement air reservoir for commercial vehicles.

• OEM Exact Fit: Optimized for Sinotruk heavy-duty truck models, it matches original mounting points and port positions for seamless installation.

Core Function

1. Stores dry, clean compressed air to provide stable pressure for the pneumatic brake system, ensuring responsive braking under heavy loads and long downhill runs—a core part of heavy duty truck brake parts.

2. Acts as a buffer to stabilize system pressure, reducing wear on air compressors and valves.

3. Supplies air for braking, suspension, gearbox, and other pneumatic accessories.

4. Fully OEM-compatible for direct replacement, restoring the air storage and pressure stability function of the pneumatic system.

Air Reservoir 20L WG9000360716 – OEM Sinotruk Air Storage Tank for Heavy-Duty Trucks

When your heavy-duty truck’s braking system demands a reliable, uninterrupted supply of compressed air, every component in the pneumatic circuit matters — especially the air reservoir. This Air Reservoir 20L WG9000360716 is a genuine OEM-spec single-chamber air storage tank engineered specifically for Sinotruk HOWO heavy-duty trucks. Built from high-strength seamless steel and finished with a durable corrosion-resistant coating, it securely stores dry compressed air that feeds your vehicle’s pneumatic brake and auxiliary systems, even under the most demanding heavy-load operations. Whether you’re assembling new vehicles on the production line or replacing a worn-out tank in the workshop, this 20L air reservoir delivers the performance and durability that procurement managers trust.

Key Features and Benefits of the Air Reservoir 20L WG9000360716

So, what makes this particular air reservoir stand out from generic alternatives? Let’s break it down:

• OEM-Grade Compatibility: Manufactured to match the exact specifications of Sinotruk part number WG9000360716, this reservoir drops right into place — no modifications, no guesswork, no downtime.
• High-Strength Seamless Steel Construction: Unlike welded tanks that can develop weak points over time, this reservoir is formed from a single piece of seamless steel, which significantly reduces the risk of leaks and fatigue cracks under constant pressure cycling.
• Corrosion-Resistant Coating: The exterior surface is treated with a protective anti-corrosion layer, helping the tank withstand road salt, moisture, and harsh environmental conditions throughout its service life.
• Optimized 20-Liter Capacity: The 20L volume is precisely calibrated to maintain adequate air pressure reserves for the braking system, ensuring consistent stopping power even during repeated heavy braking events.
• Pressure-Tested Reliability: Each unit undergoes rigorous pressure testing before leaving the factory, so you can be confident it will perform safely within the specified operating range.
• Factory-Direct Pricing: By sourcing directly from Mettlead, you eliminate middlemen and enjoy competitive wholesale pricing without sacrificing quality.

In other words, this isn’t just an air tank — it’s a critical safety component that keeps your fleet’s braking system responsive and your drivers protected on the road.

Frequently Asked Questions – Air Reservoir 20L WG9000360716

1. Is this air reservoir an original OEM part or an aftermarket replacement?

This Air Reservoir 20L WG9000360716 is manufactured to OEM specifications, meaning it matches the exact dimensions, material grade, and performance standards of the original Sinotruk factory part. It serves as a direct replacement that fits without any modification.

2. What material is the air reservoir made from, and why does it matter?

The tank is constructed from high-strength seamless steel. This matters because seamless construction eliminates weld seams — the most common failure points in pressurized vessels. As a result, the reservoir offers superior fatigue resistance and a longer service life under repeated pressure cycling.

3. How does the corrosion-resistant coating protect the air reservoir?

The exterior coating acts as a barrier against moisture, road salt, and chemical exposure. Since air reservoirs are typically mounted on the truck chassis and exposed to the elements, this protective layer prevents surface rust from developing into structural corrosion that could compromise tank integrity.

4. Can this 20L air reservoir handle the pressure demands of a fully loaded heavy truck?

Absolutely. The reservoir is engineered and pressure-tested to operate within the standard working pressure range specified by Sinotruk for their HOWO heavy-duty platform. It reliably maintains air pressure reserves even during frequent heavy braking under full-load conditions.

5. What happens if the air reservoir develops a leak or loses pressure?

A leaking air reservoir gradually depletes the stored compressed air, which can lead to reduced braking force, longer stopping distances, and eventually trigger low-pressure warning systems. If you notice any pressure drop or audible air leaks near the tank, immediate replacement is strongly recommended to maintain safe braking performance.

6. Does this air reservoir come with mounting hardware and seals?

The reservoir is supplied as the tank unit itself. Mounting brackets, straps, and port fittings are typically reused from the original installation. However, if you need specific mounting accessories or seal kits, please contact us and we’ll help you source the complete assembly.

7. Can I order this air reservoir with custom branding or private-label packaging?

Yes. Mettlead offers white-label and custom packaging services. You can have the product shipped in neutral packaging or with your own brand markings — ideal for distributors and resellers building their own aftermarket parts brand.
