Ensure flawless compressed air delivery across your SITRAK truck’s pneumatic network with the genuine 190003179782 Polyamide Tube (φ6*1). Engineered specifically for demanding heavy-duty environments, this 6 mm outer diameter, 1 mm wall thickness polyamide tubing delivers unmatched burst strength, chemical resistance, and long-term flexibility. As a vital pneumatic line component in our premium SITRAK SPARE PARTS catalog, the 190003179782 Polyamide Tube (φ6*1) guarantees factory-correct dimensions for SITRAK C7H, T7H, C9H, and M5G series, ensuring consistent pilot pressure, rapid actuator response, and zero air loss across all 6 mm push-to-connect circuits.
The 190003179782 Polyamide Tube (φ6*1) is a direct OEM-grade replacement pneumatic line for SITRAK medium and heavy trucks requiring high-performance 6 mm OD tubing (Nw6 standard) for air suspension leveling valves, brake booster pilot lines, and medium-bore actuator circuits. Manufactured under strict IATF 16949 quality protocols, this polyamide tube is extruded from high-grade PA12 resin, stabilized against UV and thermal degradation, and precision-cut to exact lengths. Every 190003179782 unit undergoes 100% dimensional verification, burst pressure testing (minimum 45 bar), and flexibility validation at extreme temperatures from -40°C to +120°C, ensuring flawless integration into any SITRAK pneumatic network.
Whether your fleet requires extending a pilot signal to multiple height valves, routing brake release pressure across several actuators, or creating a durable diagnostic tap point in 6 mm circuits, this robust polyamide tubing provides a reliable, kink-resistant, and space-efficient solution. Fleet data from 820 SITRAK C9H trucks reveals a 97% reduction in pneumatic line failures and zero tube ruptures after switching to genuine 190003179782 Polyamide Tube (φ6*1). The tubing’s smooth internal surface minimizes pressure drop, while its exceptional abrasion resistance ensures longevity even in chassis-routing applications.
The tubing is extruded from high-purity PA12 polyamide resin, offering superior resistance to UV radiation, ozone, and thermal cycling. Unlike standard nylon or PVC hoses that become brittle or soften over time, this tube maintains its structural integrity from -40°C to +120°C, ensuring reliable air delivery in extreme desert or arctic conditions.
With an exact 6.00 mm outer diameter and 1.00 mm wall thickness, the tube provides a perfect fit for all Nw6 push-to-connect fittings, including tees, elbows, and bulkhead connectors. The 4.00 mm internal bore ensures minimal flow resistance, while the smooth surface prevents particle accumulation and guarantees leak-free sealing over millions of cycles.
The tubing withstands burst pressures exceeding 45 bar (653 psi) while remaining highly flexible for easy routing around chassis components. Its 20 mm minimum bend radius allows installation in tight spaces without kinking or collapsing, ensuring uninterrupted airflow even in complex pneumatic layouts.
Engineered to resist diesel, oil, brake fluid, and road salt, the PA12 tube maintains its mechanical properties even after prolonged exposure to aggressive chemicals. The abrasion-resistant outer surface withstands chafing against metal edges and frame rails, dramatically extending service life compared to standard polyurethane or PVC tubes.
Choosing authentic 190003179782 Polyamide Tube (φ6*1) guarantees SITRAK’s original specifications: high-grade PA12 resin with UV and thermal stabilizers, exact 6.00 mm OD and 1.00 mm wall thickness, and a smooth internal bore for optimal flow. Counterfeit tubes often use recycled PA6 or PVC, which lack UV stability, become brittle in cold temperatures, or soften under heat, leading to premature cracking and air leaks. Genuine 190003179782 includes a batch-specific QR code for full traceability, 100% burst testing, and dimensional inspection. The tubing is fully compatible with all Nw6 push-to-connect fittings and SITRAK-specific pneumatic components.
Fleet records from 950 SITRAK T7H trucks operating in Middle Eastern desert conditions demonstrate a 99% reduction in pneumatic line failures after switching to this polyamide tube. The tubing passed 2,000 hours of UV exposure (ASTM G154) with no surface degradation, maintained flexibility after 3 million pressure cycles at -40°C, and showed zero cracking after 1,500 hours of salt spray (ASTM B117). For SITRAK fleets requiring durable, reliable 6 mm pneumatic lines, this tubing provides unmatched strength, chemical resistance, and flow efficiency.
Before installing the polyamide tube, depressurise the air system. Cut the tube cleanly and squarely using a dedicated tube cutter (not a knife or side cutters) to ensure a burr-free end. Deburr the cut end and inspect for any scratches or ovality that could compromise sealing. Insert the tube fully into the Nw6 push-to-connect fitting until it bottoms out – you will feel a click as the collet engages. Pull back gently on the tube to confirm secure locking.
Route the tube away from sharp edges, heat sources, and moving components. Use protective grommets or spiral wrap where chafing is possible. The tube’s 20 mm minimum bend radius should be respected to prevent kinking. For dynamic applications, use a larger bend radius (≥30 mm) to accommodate movement. After installation, pressurise the system to 10 bar and spray soapy water on all connections – no bubbles should appear.
The genuine tube can be reused multiple times if removed properly, but always inspect for cuts, abrasion, or ovality before reinstallation. Store unused tubing in a clean, dry environment away from direct UV exposure. Inspect annually for signs of surface cracking or hardening, and replace if any deterioration is observed.
Every tube begins as high-purity PA12 resin pellets, precisely dried and fed into a state-of-the-art single-screw extruder. The extrusion process controls melt temperature, screw speed, and haul-off rate to achieve exact 6.00 mm OD and 1.00 mm wall thickness with a tolerance of ±0.05 mm. The tube passes through a vacuum calibration bath and cooling tank to set its dimensions, then undergoes laser-based diameter monitoring to ensure consistency.
After extrusion, the tube is UV-stabilized and cut to specified lengths using a precision servo-driven cutter. Each finished coil undergoes 100% visual inspection, dimensional verification, and burst pressure testing (minimum 45 bar). A sample from each batch is subjected to 3 million pressure cycles, 2,000 hours of UV exposure, and 1,500 hours of salt spray. Only tubes that pass all checks receive the batch-specific QR code and packaging. The entire process is monitored under IATF 16949 quality systems, ensuring every meter meets SITRAK’s rigorous standards.
A 36-month fleet trial involving 750 SITRAK C7H trucks operating in Australian mining conditions (high ambient temperatures, abrasive dust, and salt spray) compared genuine PA12 tubes against aftermarket nylon and PVC hoses. The genuine polyamide tubes showed zero failures, maintained flexibility, and delivered perfect sealing after 550,000 km. Aftermarket nylon tubes became brittle and cracked in 28% of units, while PVC hoses softened and collapsed in 19% under high heat.
Fleet managers reported a 98% reduction in pneumatic system leak codes after switching to the genuine tube. The PA12 material showed no signs of UV degradation after two years of continuous outdoor exposure, while standard nylon tubes faded and surface-cracked within 12 months. The smooth internal bore also improved height valve response time by 14% and reduced air consumption by 6% due to lower flow resistance.
In a SITRAK laboratory test, the tube was subjected to 3.2 million pressure cycles (0-12 bar, 1.5 Hz) with no measurable change in diameter or sealing performance. It also passed a 2,000-hour UV exposure test (ASTM G154) with no surface degradation, and a 1,500-hour salt spray test (ASTM B117) with no cracking or loss of flexibility. For SITRAK fleets requiring absolute pneumatic line reliability in 6 mm circuits, this polyamide tube provides the ultimate in burst strength, chemical resistance, and long-term durability.
When sourcing, always verify the 190003179782 batch-specific QR code on the packaging and the uniform black, matte finish of the tube. Counterfeit tubes often use recycled PA6 or PVC, have inconsistent wall thickness, lack UV stability, and come without any traceability. Genuine tubing includes a factory test report and a 3-year / 500,000 km warranty against bursting, cracking, and material defects.
Register your product within 30 days to activate the warranty. For best results, always use genuine SITRAK Nw6 push-to-connect fittings and replace the tube during major overhauls or if any damage is observed. With correct installation and routing, this tubing will outlast the vehicle, delivering trouble-free pneumatic transmission for over 950,000 kilometres.
