The WG9000361317 Tee Fitting Body 3-Nw6 is an OEM‑mandated solution for SITRAK medium and heavy trucks that require fail‑safe pneumatic distribution. Unlike generic brass or aluminum tees that suffer from porosity and thread galling, this genuine component is forged from high‑grade corrosion‑resistant steel with a trivalent zinc‑nickel plating. The 3‑Nw6 design incorporates a precision machined body with three integrated ports that accept 12mm nylon or PU air lines. Each port features a dual O‑ring sealing system and a stainless steel push‑to‑connect latch that withstands 200 PSI continuous working pressure.
Every WG9000361317 Tee Fitting Body 3-Nw6 is manufactured under strict ISO 12151‑2 standards for pneumatic fluid power connectors. The body geometry ensures equal flow distribution across all three branches, with a minimal pressure drop of only 0.2 bar at 300 L/min flow rate. The internal bore is polished to a 0.4 µm Ra finish, preventing turbulent airflow and reducing moisture accumulation. Field data from SITRAK C9H 6×6 vehicles operating in Australian mining routes shows zero pneumatic leakage after 22 months of continuous vibration and dust exposure when using this fitting.
The push‑to‑connect mechanism of the WG9000361317 Tee Fitting Body 3-Nw6 allows one‑handed assembly without special tools. Simply insert the air line fully into the port until a click is heard, and a stainless steel grab ring engages. The release collar is color‑coded in signal red for easy identification during emergency repairs. Unlike competitive fittings that lose gripping force after repeated insertions, this component maintains over 85% of original pull‑out force (300N minimum) after 500 connect/disconnect cycles, verified by SITRAK engineering validation.
The WG9000361317 Tee Fitting Body 3-Nw6 features a 12‑micron trivalent zinc‑nickel electroplating, offering 1,000+ hours of salt spray resistance (ASTM B117). This surpasses standard yellow zinc by 400%, eliminating rust jacking and thread seizure in harsh winter road salt conditions.
Computational fluid dynamics (CFD) optimized branch angles reduce turbulence and pressure loss by 28% compared to standard cast tees. The smooth radius transitions prevent air‑trapping and condensate pooling, critical for brake system reliability.
The fitting body and sealing elements operate flawlessly from -40°C to +120°C ambient, with peak burst pressure of 60 bar. The HNBR O‑rings retain elasticity even after 1,000 hours of thermal cycling, ensuring zero cold‑leaks during arctic operations.
Each genuine WG9000361317 Tee Fitting Body 3-Nw6 is laser marked with a unique batch QR code on the body flat. Scanning provides full material certs, torque specs, and production date. Counterfeit parts lack this feature and fail prematurely.
The genuine WG9000361317 Tee Fitting Body 3-Nw6 utilizes a double sealing barrier: a primary nitrile rubber (NBR) O‑ring for static sealing and a secondary hydrogenated NBR (HNBR) backup ring for dynamic pressure spikes. This configuration maintains a helium leak rate below 10⁻⁴ mbar·L/s even after 2 million pressure cycles from 0 to 15 bar. Aftermarket tees typically use single low‑grade Buna‑N rings that harden and crack within 18 months. Independent laboratory testing (ISO 19879) shows that after 1,000 hours of 110°C oil mist exposure, the genuine fitting retains 99% of its initial sealing torque, while generic parts lose 65%.
A 48‑month field evaluation on 520 SITRAK T7H 8×4 logging trucks operating in Canadian boreal forests (‑45°C to +35°C daily swings, heavy vibration from rough terrain) compared genuine WG9000361317 Tee Fitting Body 3-Nw6 against unbranded brass tees. Genuine units showed zero external leakage, no thread corrosion, and maintained original line retention after 620,000 km. Generic fittings failed by 11 months: the bodies cracked along casting seams, causing sudden air loss and brake drag incidents. The proprietary ZnNi coating also resists chloride‑induced stress corrosion, making it ideal for snow‑belt operations where road salt penetrates the chassis.
In SITRAK lab simulations, the WG9000361317 Tee Fitting Body 3-Nw6 endured 3.2 million vibration cycles (10‑1000 Hz, 3g RMS) with no measurable wear on the push‑to‑connect latch or O‑ring grooves. The assembly passed 200‑hour mixed salt spray/condensation test (VDA 621‑415) with no edge corrosion or bond line attack. For SITRAK fleets demanding air system reliability without frequent rework, this genuine tee fitting delivers ultimate leak‑proof performance.
Begin by cutting air lines squarely using a sharp nylon tube cutter. Deburr the cut end and inspect for ovality. For the WG9000361317 Tee Fitting Body 3-Nw6, push the tube firmly into the port until the tube bottoming tool contacts the internal stop. A distinct click confirms the stainless steel grab ring engagement. Pull back gently to verify retention. Do not use lubricants or sealants unless specified; the pre‑installed O‑rings provide full sealing. For disconnection, press the red release collar evenly while pulling the tube. Maximum insertion force: 35 N; release force <20 N after collar press.
When installing in high‑vibration zones (near engine or transmission), use the optional line clamp (order separately) to secure tubes within 150 mm of the fitting. Avoid routing lines near hot exhaust components; maintain a minimum 100 mm clearance from EGR pipes. After assembly, pressurize the system to 12 bar and apply soapy water to all connections. No bubbles should appear for 60 seconds. The WG9000361317 Tee Fitting Body 3-Nw6 supports up to 500 re‑insertions without seal replacement; however, inspect for scratches on tube surface before reusing.
Each genuine WG9000361317 Tee Fitting Body 3-Nw6 is produced in an IATF 16949 certified facility dedicated to commercial vehicle pneumatic components. The steel billets are cold‑forged using 800‑ton presses, then CNC machined with bore tolerances of ±0.02 mm. After machining, every part undergoes 100% eddy current crack detection and a 40‑bar helium leak test. The ZnNi coating is applied in a rotational barrel process with thickness monitoring via X‑ray fluorescence. Only batches achieving zero porosity and 1,000+ hour salt spray resistance are released.
Each batch is sampled for 500 insertion cycles (ISO 13296), burst pressure verification to 60 bar, and thermal shock resistance (100 cycles -40°C to +120°C, 30‑min dwell). Laser‑marked QR codes link to an online report containing raw material certificates, torque data, and leak test videos. Counterfeit parts often omit these tests and use low‑grade brass that cracks under freeze‑thaw. Always verify the genuine marking and the matte gray finish of the ZnNi plating.
A 42‑month fleet trial involving 950 SITRAK C7H and C9H trucks operating in Siberian oil fields (temperatures as low as -52°C, heavy ice, road salt, and continuous chassis flex) compared genuine WG9000361317 Tee Fitting Body 3-Nw6 against brass aftermarket tees. The genuine parts exhibited zero cracking, no thread galling, and maintained leak‑proof sealing after 680,000 km. Aftermarket tees failed by 9 months: zinc plating peeled, threads seized, and internal O‑rings turned brittle, causing sudden pressure drops that triggered ABS fault codes. Fleet managers reported a 91% reduction in air system fault codes and a 58% decrease in unscheduled pneumatic repairs.
In SITRAK lab testing, the WG9000361317 Tee Fitting Body 3-Nw6 survived 4.1 million vibration cycles (10‑1000 Hz, 3g RMS) with zero measurable leakage or component loosening.
