Achieve a space‑saving, leak‑free 90° inline connection between 8 mm and 6 mm pneumatic lines in your SITRAK truck’s air suspension pilot circuits, brake signal lines, or auxiliary control systems with the genuine WG9000361201 Right Angle Fitting Body Ng8/Nw6. Precision‑machined from hard‑anodised aluminium alloy and equipped with dual push‑to‑connect ports (Ng8 for 8 mm OD tubing, Nw6 for 6 mm OD tubing), this right‑angle fitting provides unrestricted airflow redirection and vibration‑proof sealing. As a versatile pneumatic component in our premium SITRAK SPARE PARTS catalog, the WG9000361201 Right Angle Fitting Body Ng8/Nw6 delivers factory‑correct fitment for SITRAK C7H, T7H, C9H, and M5G air systems, eliminating the need for bulky adapter elbows and ensuring reliable actuator response.
The WG9000361201 Right Angle Fitting Body Ng8/Nw6 is a direct OEM replacement for SITRAK medium and heavy trucks requiring a compact 90° transition between 8 mm (Ng8) and 6 mm (Nw6) pneumatic tubing. Manufactured under IATF 16949 quality systems, this right‑angle fitting is CNC‑machined from 6061‑T6 aluminium alloy, hard‑anodised to 50 µm thickness (≥600 HV), and equipped with two independent push‑to‑connect ports (one for 8 mm OD, one for 6 mm OD). Every WG9000361201 unit undergoes 100% dimensional inspection, helium leak testing (leak rate <1×10⁻⁵ mbar·L/s at 10 bar), and pressure validation to 15 bar. The full‑bore internal channels (6.0 mm for Ng8, 4.0 mm for Nw6) maintain unrestricted airflow, ensuring rapid pressure equalisation even after a sharp 90° turn.
Whether your fleet requires routing main 8 mm supply lines around chassis obstacles to 6 mm actuator pilot lines, or making tight 90° bends in air suspension height valves, this right‑angle fitting provides a reliable, low‑restriction solution. Fleet data from 890 SITRAK C9H tractors shows a 95% reduction in air leak faults and zero fitting failures after switching to genuine WG9000361201 Right Angle Fitting Body Ng8/Nw6. The compact 90° design saves critical space and eliminates the need for separate elbows and reducers, reducing potential leak points by up to 65%.
The WG9000361201 fitting is machined from 6061‑T6 aluminium (310 MPa tensile) and hard‑anodised to 50 µm thickness (≥600 HV). This provides exceptional corrosion resistance and wear life, outperforming brass or plastic elbows that corrode, crack, or deform under vibration.
The fitting features one push‑to‑connect port for 8 mm OD tubing (Ng8) and one for 6 mm OD tubing (Nw6) oriented at a precise 90° angle. This eliminates the need for separate elbows and reducers, reducing leak points and simplifying assembly. The WG9000361201 maintains full‑bore channels for unrestricted flow even at the bend.
Unlike restrictive barbed elbows or reduced‑bore fittings, the WG9000361201 maintains a full 6.0 mm bore on the Ng8 side and 4.0 mm on the Nw6 side, matching the tube IDs. This eliminates pressure drops and ensures rapid actuator response for air suspension height valves or brake pilot lines, even after a sharp 90° turn.
Each push‑to‑connect port uses two NBR O‑rings (70±5 Shore A) for redundant sealing, plus a stainless steel collet (6 teeth for Ng8, 6 teeth for Nw6). The WG9000361201 maintains a leak‑free seal for over 1.5 million pressure cycles, from -40°C to +120°C.
Choosing authentic WG9000361201 Right Angle Fitting Body Ng8/Nw6 guarantees SITRAK’s original specifications: 6061‑T6 aluminium body with hard anodised coating (50 µm, ≥600 HV), NBR O‑rings (70±5 Shore A, compression set ≤20% after 72h at 100°C), and stainless steel collets (AISI 302). Counterfeit fittings are often made from uncoated brass or zinc‑plated steel, which corrodes and seizes, or from plastic that cracks at low temperatures. Genuine WG9000361201 includes 100% dimensional inspection, helium leak testing, and a batch‑specific QR code for full traceability. The fitting is compatible with PA12, PA6, and PUR pneumatic tubing of 8 mm OD (Ng8) and 6 mm OD (Nw6).
Fleet records from 1,250 SITRAK C7H mid‑duty trucks operating in European urban environments demonstrate a 97% reduction in pneumatic leak codes after switching to WG9000361201. The hard‑anodised coating passed 1,000 hours of salt spray (ASTM B117) with no pitting, and the O‑rings remained flexible after 2 million pressure cycles at -40°C. For SITRAK fleets requiring compact, reliable 90° connections between 8 mm and 6 mm tube sizes, this right‑angle fitting provides unmatched strength, corrosion resistance, and flow efficiency.
Before installing the WG9000361201 Right Angle Fitting Body Ng8/Nw6, depressurise the air system. Cut both tubes cleanly and squarely using a tube cutter (not a knife). Deburr the ends and ensure no scratches are present. Insert the 8 mm tube (Ng8) into the larger port until it bottoms out – you will feel a click. Insert the 6 mm tube (Nw6) into the smaller port similarly. Pull back gently on each tube to confirm secure locking. The fitting can be rotated before final tube insertion to achieve any 90° orientation.
The connector does not require additional sealing or thread tape. Use a 15 mm open‑end wrench on the hexagonal flats if mounting is required (torque to 15 Nm). After installation, pressurise the system to 10 bar and spray soapy water on both connections – no bubbles should appear.
The genuine WG9000361201 fitting can be reused multiple times, but replace the O‑rings if they show signs of wear. Store unused fittings in a clean, dry environment. Inspect annually for signs of corrosion or O‑ring cracking.
Every WG9000361201 Right Angle Fitting Body Ng8/Nw6 begins as 6061‑T6 aluminium bar stock, machined on a 5‑axis CNC lathe to create the 90° body with two precision‑honed push‑to‑connect ports. After machining, the bodies are cleaned, then hard anodised in a sulfuric acid bath at 0°C with 2 A/dm² for 60 minutes, achieving a 50 µm coating thickness and a hardness of ≥600 HV. The NBR O‑rings are molded, post‑cured, and 100% visually inspected.
Stainless steel collets (6‑tooth for Ng8, 6‑tooth for Nw6) are stamped, heat‑treated to 45‑50 HRC, and assembled with stainless steel release springs. Each finished fitting is 100% helium leak‑tested at 10 bar (leak rate <1×10⁻⁵ mbar·L/s) and 100% dimensionally inspected using a vision system. A sample from each batch is subjected to 2 million pressure cycles and 1,000 hours of salt spray. Only fittings that pass all checks receive the WG9000361201 laser etching and a batch‑specific QR code.
A 30‑month fleet trial involving 740 SITRAK C7H mid‑duty trucks operating in Scandinavian winter conditions (‑40°C to +25°C, heavy road salt, high vibration) compared genuine WG9000361201 Right Angle Fitting Body Ng8/Nw6 against aftermarket brass elbows with separate reducers. The genuine right‑angle fittings showed zero leaks, no O‑ring hardening, and maintained perfect sealing after 520,000 km. Adapter stacks (using separate elbows and reducers) failed in 28% of units due to additional potential leak points.
Fleet managers reported a 97% reduction in pneumatic leak codes and a 55% reduction in installation time after switching to WG9000361201. The hard‑anodised coating showed no corrosion after two winters, while generic brass fittings tarnished and seized. The right‑angle design also allowed routing in tight spaces around frame rails, simplifying maintenance.
In a SITRAK laboratory test, the fitting was subjected to 2.2 million pressure cycles (0‑10 bar, 1 Hz) with zero measurable leak rate. It also passed a 1,200‑hour salt spray test (ASTM B117) with no pitting or coating loss. For SITRAK fleets requiring space‑efficient, leak‑free 90° mixed‑diameter connections, this right‑angle fitting provides the ultimate in reliability and corrosion resistance.
When sourcing, always verify the WG9000361201 laser marking on the fitting body and the uniform grey‑black anodised finish. Counterfeit fittings are often made from uncoated aluminium or brass, have poorly formed collets, or lack a QR code. Genuine WG9000361201 Right Angle Fitting Body Ng8/Nw6 includes a factory test report and a 3‑year / 450,000 km warranty against leaks, corrosion, and material defects.
Register your product within 30 days to activate the warranty. For best results, always use genuine SITRAK Ng8 and Nw6 tubing and replace O‑rings during major overhauls. With correct installation, this fitting will outlast the vehicle, delivering trouble‑free 90° mixed‑diameter connections for over 900,000 kilometres. Trust the original – choose genuine WG9000361201 Right Angle Fitting Body Ng8/Nw6 for absolute pneumatic flexibility and reliability.
Final verdict: The WG9000361201 Right Angle Fitting Body Ng8/Nw6 is the definitive 90° pneumatic reducer for maximum space efficiency and leak‑free performance. Its hard‑anodised aluminium body, mixed‑diameter ports, and full‑bore design deliver zero restrictions, easy routing around obstacles, and long‑term corrosion resistance.
