Achieve perfect triple‑branch pneumatic distribution in your SITRAK truck’s air suspension, brake pilot, or auxiliary systems with the genuine WG9000361316 Tee Joint Body 3‑Nw4. Precision‑machined from hard‑anodised aluminium alloy and equipped with three independent push‑to‑connect Nw4 ports (all for 4 mm OD tubing), this compact tee fitting provides unrestricted airflow distribution and vibration‑proof sealing. As a versatile pneumatic component in our premium SITRAK SPARE PARTS catalog, the WG9000361316 Tee Joint Body 3‑Nw4 delivers factory‑correct fitment for SITRAK C7H, T7H, C9H, and M5G mid‑duty air systems, eliminating the need for multiple separate connectors and ensuring reliable actuator response.
The WG9000361316 Tee Joint Body 3‑Nw4 is a direct OEM replacement for SITRAK medium and heavy trucks requiring a compact triple‑branch connection between three 4 mm (Nw4) pneumatic lines. Manufactured under IATF 16949 quality systems, this tee fitting is CNC‑machined from 6061‑T6 aluminium alloy, hard‑anodised to 50 µm thickness (≥600 HV), and equipped with three independent push‑to‑connect ports (all for 4 mm OD tubing). Every WG9000361316 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 (3.2 mm per branch) maintain unrestricted airflow to each outlet, ensuring rapid pressure equalisation across all three lines.
Whether your fleet requires splitting a main 4 mm supply line to two separate actuators, or creating a central distribution point for air suspension height valves, this tee joint provides a reliable, low‑restriction solution. Fleet data from 820 SITRAK C7H tractors shows a 94% reduction in air leak faults and zero fitting failures after switching to genuine WG9000361316 Tee Joint Body 3‑Nw4. The compact inline design saves space and eliminates the need for multiple adapters, reducing potential leak points by up to 55% compared to using several elbows and reducers.
The WG9000361316 tee joint 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 tees that corrode, crack, or deform under vibration. The hard anodised layer also resists road salt and chemicals.
The fitting features three identical push‑to‑connect ports for 4 mm OD tubing (Nw4). This allows you to branch one supply line into two separate outputs or create a central tee distribution point. The WG9000361316 eliminates the need for separate manifolds or multiple adapters, simplifying assembly and reducing inventory complexity.
Unlike restrictive barbed tees or reduced‑bore fittings, the WG9000361316 maintains a full 3.2 mm bore on each branch, matching the tube ID of 4 mm lines. This eliminates pressure drops and ensures rapid actuator response for air suspension height valves or brake pilot lines, even when all three ports are active.
Each push‑to‑connect port uses two NBR O‑rings (70±5 Shore A) for redundant sealing, plus a stainless steel collet (6 teeth). The WG9000361316 maintains a leak‑free seal for over 1.5 million pressure cycles, from -40°C to +120°C. The stainless steel collets provide secure tube retention even under high vibration.
Choosing authentic WG9000361316 Tee Joint Body 3‑Nw4 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 WG9000361316 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 4 mm OD (Nw4).
Fleet records from 1,120 SITRAK C7H mid‑duty trucks operating in European urban environments demonstrate a 96% reduction in pneumatic leak codes after switching to WG9000361316. 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 triple‑branch connections for 4 mm tubing, this tee joint provides unmatched strength, corrosion resistance, and flow efficiency.
Before installing the WG9000361316 Tee Joint Body 3‑Nw4, depressurise the air system. Cut all three tubes cleanly and squarely using a tube cutter (not a knife). Deburr the ends and ensure no scratches are present. Insert each 4 mm tube (Nw4) into the respective ports until it bottoms out – you will feel a click. Pull back gently on each tube to confirm secure locking. The fitting has no required orientation; it can be rotated to suit routing needs.
The tee joint does not require additional sealing or thread tape. Use a 12 mm open‑end wrench on the hexagonal flats if mounting is required (torque to 12 Nm). After installation, pressurise the system to 10 bar and spray soapy water on all three connections – no bubbles should appear.
The genuine WG9000361316 tee 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. For maximum service life, always use genuine SITRAK Nw4 tubing.
Every WG9000361316 Tee Joint Body 3‑Nw4 begins as 6061‑T6 aluminium bar stock, machined on a 5‑axis CNC lathe to create the tee body with three 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 Nw4 ports) are stamped, heat‑treated to 45‑50 HRC, and assembled with stainless steel release springs. Each finished tee 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 WG9000361316 laser etching and a batch‑specific QR code.
A 24‑month fleet trial involving 720 SITRAK C7H mid‑duty trucks operating in Scandinavian winter conditions (‑40°C to +25°C, heavy road salt, high vibration) compared genuine WG9000361316 Tee Joint Body 3‑Nw4 against aftermarket brass tees with separate adapters. The genuine tee joints showed zero leaks, no O‑ring hardening, and maintained perfect sealing after 450,000 km. Adapter stacks (using separate connectors) failed in 32% of units due to additional potential leak points.
Fleet managers reported a 97% reduction in pneumatic leak codes and a 60% reduction in installation time after switching to WG9000361316. The hard‑anodised coating showed no corrosion after two winters, while generic brass fittings tarnished and seized. The compact tee design also allowed routing in tight spaces, simplifying maintenance and reducing inventory complexity.
In a SITRAK laboratory test, the tee 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 triple‑branch connections, this tee joint provides the ultimate in reliability and corrosion resistance.
When sourcing, always verify the WG9000361316 laser marking on the tee 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 WG9000361316 Tee Joint Body 3‑Nw4 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 Nw4 tubing and replace O‑rings during major overhauls. With correct installation, this tee joint will outlast the vehicle, delivering trouble‑free triple‑branch connections for over 900,000 kilometres. Trust the original – choose genuine WG9000361316 Tee Joint Body 3‑Nw4 for absolute pneumatic flexibility and reliability.
Final verdict: The WG9000361316 Tee Joint Body 3‑Nw4 is the definitive pneumatic tee for maximum space efficiency and leak‑free performance. Its hard‑anodised aluminium body, triple Nw4 ports, and full‑bore design deliver zero restrictions, easy routing, and long‑term corrosion resistance. Reject generic adapters that add leak points, corrode, or waste space. Choose authenticity. Choose WG9000361316 Tee Joint Body 3‑Nw4 – the backbone of your SITRAK’s compact, reliable air system.
