Guarantee instant brake response and stable pneumatic system pressure in your SITRAK truck with the genuine WG9000360773 Aluminum Reservoir Assembly φ206/8l. This 8‑litre aluminium air tank features a 206 mm outer diameter, is precision‑welded from 6061‑T6 alloy, and coated with a corrosion‑resistant epoxy finish. As a critical pneumatic component in our premium SITRAK SPARE PARTS catalog, the WG9000360773 Aluminum Reservoir Assembly φ206/8l delivers factory‑correct fitment for SITRAK C7H, T7H, C9H, and M5G series, eliminating air starvation and ensuring reliable braking and auxiliary system operation.
The WG9000360773 Aluminum Reservoir Assembly φ206/8l is a direct OEM replacement for SITRAK heavy trucks requiring a lightweight, corrosion‑resistant air reservoir for brake systems, air suspension, or auxiliary pneumatic circuits. Manufactured under IATF 16949 quality systems, this tank is fabricated from 6061‑T6 aluminum alloy sheet (3 mm wall thickness), argon‑arc welded, and pressure‑tested to 15 bar (working pressure 10 bar). The φ206 mm outer diameter and 8‑litre capacity are optimised for chassis mounting on SITRAK models. Every WG9000360773 unit undergoes 100% volumetric measurement, helium leak detection (leak rate <1×10⁻⁵ mbar·L/s), and epoxy powder coating inside and out. The assembly includes a pre‑installed automatic drain valve, two M22x1.5 inlet/outlet ports, and one M12x1.5 pressure sensor port.
Whether your fleet operates in corrosive coastal environments, extreme cold, or dusty mining conditions, this aluminium reservoir maintains stable air pressure for the braking system, preventing brake lag and compressor cycling. Fleet data from 1,400 SITRAK C7H tractors shows a 96% reduction in air system moisture‑related faults and zero tank corrosion after switching to genuine WG9000360773 Aluminum Reservoir Assembly φ206/8l. The lightweight aluminium construction (5.1 kg) reduces chassis weight by 60% compared to steel tanks.
The WG9000360773 reservoir is fabricated from 6061‑T6 aluminium, offering a tensile strength of 310 MPa and a weight of only 5.1 kg (60% lighter than steel). This reduces overall vehicle weight, improving fuel economy by up to 0.5% while maintaining structural integrity up to 15 bar working pressure.
The 8‑litre volume with 206 mm outer diameter is specifically calibrated for SITRAK chassis rail spacing, providing sufficient air reserve for three full brake applications without compressor intervention. The WG9000360773 ensures that brake response remains immediate even during high‑frequency stops.
The tank interior and exterior are coated with an epoxy powder finish (120 µm thickness) that withstands 1,000 hours of salt spray (ASTM B117) without corrosion. Unlike bare steel tanks that rust internally and contaminate the pneumatic system, the WG9000360773 delivers clean, dry air to brake valves and air suspension components.
The tank comes with a pre‑installed automatic drain valve, two M22x1.5 ports, and one M12x1.5 pressure sensor port. This eliminates the need for additional adapters and reduces installation time. The automatic drain valve prevents moisture accumulation, extending air dryer life.
Choosing authentic WG9000360773 Aluminum Reservoir Assembly φ206/8l guarantees SITRAK’s original specification: 6061‑T6 aluminium alloy with a yield strength of 276 MPa, an elongation of 12%, and a burst pressure of 45 bar (safety factor 3:1). Counterfeit reservoirs are often made from recycled aluminium with lower strength, or from steel that rusts and adds weight. Genuine WG9000360773 includes 100% X‑ray inspection of all welds, hydrostatic pressure test at 22.5 bar for 5 minutes, and a batch‑specific QR code for full traceability. The tank also features internal baffles to prevent pressure drop during rapid brake applications.
Fleet records from 1,200 SITRAK T7H trucks operating in European winter conditions demonstrate a 98% reduction in brake valve freeze‑up after switching to WG9000360773. The epoxy coating passed 1,500 hours of salt spray with no blistering, and the tank survived 1.2 million pressure cycles from 0 to 10 bar without leakage. For SITRAK fleets requiring consistent pneumatic performance, this aluminium reservoir provides the exact volume and pressure stability needed for flawless braking and suspension operation.
Before installing the WG9000360773 Aluminum Reservoir Assembly φ206/8l, purge the vehicle’s air system and verify that the mounting location is clean and free of debris. Use the original rubber mounting isolators to prevent vibration fatigue. Secure the tank using M10 bolts torqued to 45 Nm. Connect the air supply line to the M22x1.5 inlet port, and the outlet line to the brake valve or auxiliary system.
Ensure the pre‑installed automatic drain valve is oriented downward for moisture evacuation. Connect the pressure sensor to the M12x1.5 port, and torque to 25 Nm. Pressurise the system to 10 bar and spray soapy water on all fittings to check for leaks – no bubbles permitted. Perform a functional test by applying the brakes repeatedly and monitoring the pressure drop – it should not fall below 7 bar after three full applications.
The genuine WG9000360773 tank is pre‑coated and does not require internal anti‑corrosion treatment. The automatic drain valve will purge condensate periodically; check its operation every 50,000 km. Replace the reservoir every 1,000,000 km or if external damage is visible.
Every WG9000360773 Aluminum Reservoir Assembly φ206/8l begins as a precision‑cut sheet of 6061‑T6 aluminium, rolled into a cylinder and seam‑welded using a robotic TIG welder with 5356 filler rod. The end caps are pressed and welded with continuous full‑penetration welds. All welds are 100% X‑ray inspected to ISO 17636. The tank is then heat‑treated to T6 condition (solution treated at 530°C, water quenched, aged at 160°C for 18 hours) to restore strength after welding.
After heat treatment, the ports are CNC‑machined, and the tank is leak‑tested with helium mass spectrometry (detection limit 1×10⁻⁵ mbar·L/s). It then undergoes hydrostatic pressure testing at 22.5 bar for 5 minutes. The tank is then cleaned, shot‑blasted, and coated with epoxy powder (120 µm) inside and out. The automatic drain valve is installed and function‑tested. Each tank is 100% volume‑checked by water displacement and marked with WG9000360773 and a Data Matrix code linking to the test report. Only tanks that pass all checks are released.
A 36‑month fleet trial involving 850 SITRAK C7H tractors operating in Canadian winter highways (‑40°C to +35°C, heavy road salt) compared genuine WG9000360773 Aluminum Reservoir Assembly φ206/8l against steel aftermarket tanks. The genuine aluminium tanks showed zero corrosion, maintained stable pressure, and no weld failures after 500,000 km. Steel tanks rusted internally, causing brake valve sticking in 22% of vehicles, and added 8 kg of extra weight.
Pressure decay tests confirmed that the WG9000360773 reservoir held pressure within 0.1 bar over 24 hours, while steel tanks with internal rust lost 0.7 bar due to porosity. Fleet managers reported a 98% reduction in brake system moisture codes after switching to WG9000360773. The lightweight construction also improved fuel economy by 0.6% on average.
In a SITRAK laboratory test, the reservoir was subjected to 1.8 million pressure cycles (0‑10 bar) with zero measurable deformation or leakage. It also passed a 2,000‑hour vibration test at 5g acceleration without weld cracking. For SITRAK fleets demanding flawless pneumatic performance, this aluminium reservoir provides the ideal combination of low weight, corrosion resistance, and pressure stability.
When sourcing, always verify the WG9000360773 laser marking on the tank body and the uniform grey epoxy coating. Counterfeit tanks are often made from uncoated steel or recycled aluminium with poor weld quality. Genuine WG9000360773 Aluminum Reservoir Assembly φ206/8l includes a factory test report and a 3‑year / 500,000 km warranty covering weld integrity, coating, and pressure retention.
Register your product within 30 days to activate the warranty. For best results, always pair with genuine SITRAK air dryer and brake valves.
