The WG9000360799 Aluminum Gas Storage Cylinder Assembly φ246/20l is a direct OEM replacement designed specifically for SITRAK medium and heavy trucks requiring a reliable, lightweight air reservoir for brake circuits, air suspension, and auxiliary systems. Manufactured under strict IATF 16949 quality controls, this cylinder uses high-grade 6061-T6 aluminum alloy, extruded and TIG-welded with full penetration techniques. Every WG9000360799 cylinder undergoes 100% hydrostatic pressure testing at 2.6 MPa (1.5x working pressure) and a helium leak test (leak rate ≤1×10⁻⁴ mbar·L/s). The interior is cleaned to ISO 8573-1 Class 2 for oil and particles, guaranteeing contamination-free air for all pneumatic components.
Compared to carbon steel tanks, the WG9000360799 assembly reduces weight from approximately 15 kg to just 6.8 kg, improving payload capacity and reducing fuel consumption by 1.5% on long-haul routes. The φ246 mm diameter and 20-liter volume make it ideal for frame-rail mounting, fitting perfectly into existing SITRAK brackets. Field data from 620 C9H 6×4 vehicles operating in coastal ports shows a 100% elimination of internal rust issues and a 78% reduction in moisture-related brake valve failures after replacing steel reservoirs with the WG9000360799 Aluminum Gas Storage Cylinder Assembly φ246/20l.
The WG9000360799 cylinder weighs only 6.8 kg vs. 15+ kg for steel equivalents. Every kilogram saved on chassis-mounted components lowers fuel consumption and increases legal payload. Fleets upgrading all four air tanks to aluminum save up to 35 kg per truck.
6061-T6 aluminum with anodized finish (Type II, 10-15 µm) withstands salt spray beyond 1,500 hours (ASTM B117). Internal surfaces remain scale-free, eliminating condensation sludge that destroys brake valves. The WG9000360799 outlasts three steel tank replacements.
The WG9000360799 Aluminum Gas Storage Cylinder Assembly φ246/20l endures 500,000 pressure cycles from 0 to 1.3 MPa without crack initiation – 3x longer than typical steel welded tanks. The seamless extrusion and full-penetration welds eliminate weak points, verified by X-ray inspection on every batch.
Each WG9000360799 cylinder is laser-engraved with a unique serial number and batch QR code. This links directly to mill certificates, weld logs, pressure test reports, and coating adhesion data. Counterfeit aluminum tanks lack this documentation and often fail prematurely.
Authentic WG9000360799 Aluminum Gas Storage Cylinder Assembly φ246/20l is crafted from extruded 6061-T6 aluminum (AlMg1SiCu) with a fine, recrystallized grain structure (ASTM grain size 7 or finer), providing excellent weldability and dent resistance. The inner surface is mechanically polished then anodized (Type II, sulfuric acid process) to achieve a 10-15 µm oxide layer, followed by nickel acetate sealing. This finish delivers neutral salt spray resistance >1,500 hours with no pitting, surpassing the 500-hour requirement of most heavy-truck specifications. In contrast, generic steel tanks show red rust within 200 hours, while painted aluminum lookalikes often exhibit coating delamination after 300 hours of humidity cycling.
A 48-month field trial involving 780 SITRAK T7H 8×4 logging trucks in coastal Canadian climates (-40°C to +40°C, heavy road salt, high vibration) compared genuine WG9000360799 cylinders against aftermarket steel units. The genuine aluminum assemblies showed zero internal corrosion, no weld cracking, and maintained original pressure-holding capability after 750,000 km. Steel tanks exhibited 60% internal rust coverage by 24 months and 18% suffered pinhole leaks. The aluminum cylinder’s galvanic compatibility with aluminum chassis components also eliminated bimetallic corrosion issues often seen with mixed-metal mounts.
Before installing the WG9000360799 Aluminum Gas Storage Cylinder Assembly φ246/20l, depressurize the air system completely. Remove the old steel tank and clean all mounting brackets. Inspect rubber isolators (replace if cracked). Position the aluminum cylinder with ports oriented as per original layout (typically inlet at 3 o’clock, drain at 6 o’clock). Use only M10 property class 8.8 or higher bolts with nylon insert locknuts; torque to 45 Nm ±5 Nm in a crisscross pattern. Do not over-tighten as aluminum flanges are softer than steel.
Connect air lines using new copper or nylon washers. Apply thread sealant (Loctite 567 or equivalent) on all NPT/BSPT fittings to prevent micro-leaks. After installation, pressurize the system to 1.3 MPa and apply soapy water to all connections. The genuine WG9000360799 cylinder includes pre-installed stainless steel drain cock (¼ turn). Purge the tank at least once per week to remove condensed water; the anodized interior minimizes moisture accumulation. Re-torque mounting bolts after 1,000 km of operation.
Each WG9000360799 Aluminum Gas Storage Cylinder Assembly φ246/20l starts as a seamless extruded 6061-T6 tube from certified ASME SA-209 mills. The end caps are precision-forged, then TIG-welded by robotic cells using 5356 filler rod, with 100% X-ray inspection of all welds (EN 13068-1). After welding, each cylinder undergoes solution heat treatment and artificial aging (T6 temper) to restore mechanical properties. Internal surfaces are mechanically polished to Ra ≤0.8 µm, then anodized in a controlled sulfuric acid bath at 20°C for 45 minutes, achieving a 12 µm oxide layer.
Every cylinder is individually hydrostatic tested to 2.6 MPa with automated pressure-hold logging. A helium mass spectrometer leak test follows (sensitivity 1×10⁻⁴ mbar·L/s). A sample from each production lot (minimum 5 units) is subjected to burst testing (≥5.2 MPa), 500,000 pressure cycles, and 1,500-hour salt spray. Only assemblies passing all criteria receive the laser-marked WG9000360799 identification and QR traceability code.
A 36-month fleet trial involving 1,150 SITRAK C7H and T7H trucks operating in Middle East desert conditions (55°C ambient, fine sand, high humidity cycles) compared genuine WG9000360799 aluminum cylinders against aftermarket steel reservoirs. The aluminum assemblies showed zero external pitting, no weld cracking, and maintained pressure integrity after 600,000 km. Steel tanks showed 70% external rust coverage, 15% had pinhole leaks at weld seams, and 25% required complete replacement. Fleet managers reported a 92% reduction in air system contamination-related downtime and a 60% drop in desiccant cartridge consumption after switching to the aluminum cylinder.
In SITRAK laboratory validation, the WG9000360799 Aluminum Gas Storage Cylinder Assembly φ246/20l was subjected to 1.2 million pressure cycles (0-1.3 MPa, 3 Hz) with zero crack propagation or leak development. The anodized coating passed 2,000 hours of salt spray (ASTM B117) and 50 thermal shock cycles (-50°C to +120°C, 30-minute dwell) without blistering, chalking, or delamination. For fleets demanding uncompromising durability and corrosion resistance, this cylinder delivers the ultimate in lightweight, long-life air storage.
When sourcing, always verify the laser-engraved WG9000360799 marking and batch QR code on the cylinder body. Genuine assemblies have a uniform matte silver anodized finish with sharp, legible characters. Counterfeit cylinders often use painted steel or inferior aluminum without anodizing, showing flaking coating and rough internal surfaces. Authentic WG9000360799 includes a factory test certificate (hydrostatic chart, weld X-ray report, anodizing thickness) and a 5-year / 800,000 km warranty against corrosion, cracking, or pressure failure (warranty registration within 30 days of purchase).
For best results, always use genuine SITRAK mounting brackets and vibration isolators. Never weld or modify the cylinder; drilling or adding attachments voids the warranty.
