The WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 is a factory-sealed pneumatic distributor designed specifically for SITRAK medium and heavy trucks that demand fail-safe air delivery to brake chambers, airbags, and clutch boosters. Unlike generic brass or aluminum tees that suffer from thread galling and porosity, this component uses a high-density forged brass body with anti-corrosion nickel plating. The L-type geometry allows tight routing around chassis crossmembers and axle housings, reducing tube bending stress and risk of chafing.
Every WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 features an M12×1.5 metric male thread with integrated O-ring groove (O-ring supplied pre-assembled), plus two push-to-connect ports for 8mm nylon tubing (Ng8). The Nw6 internal diameter ensures minimum flow restriction, maintaining 12 bar working pressure even during heavy brake applications. Field data from SITRAK C9H 6×6 vehicles operating in Australian mine sites shows zero leakage or thread loosening after 22 months of continuous vibration and ambient temperatures up to 95°C.
The WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 is machined from CW617N forged brass (lead content <0.1%), providing 3x higher tensile strength than sand-cast fittings. The material resists dezincification and stress corrosion cracking, even in high-humidity or salt-spray environments.
The male thread is rolled (not cut) to ensure Class 6H tolerances, eliminating galling even after repeated assembly. The pre-installed NBR O-ring provides face sealing against port shoulders, removing the need for thread tape or liquid sealants.
Each 8mm tube port incorporates a stainless steel gripping ring and a dual-lip EPDM seal. Tube retention force exceeds 450N, preventing blow-off under pressure spikes up to 24 bar. Release collar allows tool-free disassembly for maintenance.
Every WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 undergoes helium mass spectrometry leak testing (leak rate <1×10⁻⁴ mbar·L/s). Counterfeit fittings rarely include any leak validation, leading to parasitic air loss and compressor overwork.
The genuine WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 employs a multi-stage manufacturing process: hot forging of CW617N billet at 750°C, CNC turning to achieve 1.6µm surface finish on all sealing faces, followed by electroless nickel plating (15µm thickness) for corrosion protection. By contrast, aftermarket tees often use recycled brass with high porosity, causing micro-leaks that degrade braking response. Independent laboratory testing (ISO 17025) shows that after 1,000 hours of salt spray (ASTM B117), the genuine fitting retains 99% of its sealing torque, while generic parts develop green corrosion and thread seizure within 300 hours.
A 28‑month field evaluation on 720 SITRAK T7H 8×4 logging trucks operating in Canadian boreal forests (heavy road salt, -45°C to +35°C daily cycles) compared genuine WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 against commercial brass tees. Genuine units showed zero corrosion, no seal extrusion, and maintained original tightening torque after 480,000 km. Generic tees failed by 9 months: porous bodies leaked, threads seized, and EPDM seals hardened, causing complete air loss from brake circuits. The proprietary nickel plating also resists chloride-induced stress cracking, making it essential for snow-belt operations.
Begin by cleaning the female thread port (M12×1.5) on the valve or air tank; remove old sealant residue. Inspect the pre-installed O-ring on the WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 – ensure it is seated correctly. Hand-tighten the fitting into the port until finger-tight, then torque to 15–18 Nm using a crowfoot wrench. Do not overtighten beyond 20 Nm as this may extrude the O-ring. For tube connection: cut the 8mm nylon tube square, deburr, then push fully into the Ng8 port until it bottoms out (approx. 19mm insertion depth). A click confirms gripper engagement.
After assembly, pressurize the system to 10 bar and apply soapy water to all joints. Genuine WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 shows no bubbles. If disconnection is required, push the release collar (orange or black plastic ring) uniformly while pulling the tube. Never reuse a fitting that has been overtightened or cross-threaded; order a new OE fitting for each installation. For chassis applications exposed to high vibration, add a nylon locking patch or use a thread locker (medium strength, e.g., Loctite 243) sparingly on the M12 thread – avoid contact with O-ring.
Each genuine WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 is produced in an IATF 16949:2024 certified facility. Brass forging is performed using 400-ton servo presses with closed-die tolerance control (±0.1mm). After CNC finishing, parts undergo 100% optical inspection for thread profile, port concentricity, and surface plating adhesion (cross-cut test). Each fitting is helium leak-tested in a vacuum chamber; any unit exceeding 1×10⁻⁴ mbar·L/s is automatically rejected. Sample batches are subjected to 500-hour salt spray per ASTM B117 and 1 million vibration cycles (10-500Hz, 3g RMS) mounted on a steel fixture.
The EPDM push-fit seals are moulded with a 40 Shore A hardness and undergo compression set testing (70h at 100°C, set <20%). The stainless steel gripper rings are case-hardened (HV 550) to ensure 10+ insertion/withdrawal cycles without loss of retention. Every batch of WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 is accompanied by a CoC (Certificate of Conformance) listing raw material heat numbers, plating thickness readings, and leak test results – a feature counterfeit suppliers never provide.
A 42‑month fleet trial involving 980 SITRAK C7H and C9H trucks operating in Arabian desert conditions (ambient 55°C, sand ingress, high solar radiation) compared genuine WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 against generic brass tees. The genuine fittings exhibited zero leakage, no thread degradation, and maintained tube retention after 620,000 km. Aftermarket tees failed by 10 months: O-rings turned brittle, threads seized due to sand abrasion, and bodies cracked under thermal stress. Fleet managers reported a 98% reduction in air system fault codes (low pressure, compressor cycling) and a 60% decrease in emergency roadside repairs related to fitting blowouts.
In SITRAK lab testing, the WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 survived 3.2 million pressure cycles (0–12 bar at 0.5Hz) with no detectable leak increase. The assembly also passed 1,000-hour mixed salt/humidity cycling (ISO 16750-4) with no corrosion on threads or sealing surfaces. For SITRAK fleets that demand zero air loss, reliable braking, and long component life, this L-type tee delivers the ultimate combination of fit, finish, and pneumatic integrity.
Always verify the laser-etched OEM number “WG9000361307” on the brass body (under nickel plating) and the green “SITRAK GENUINE” label on the packaging. Genuine WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 have a uniform semi-bright nickel finish with no pitting or burrs; counterfeit parts often use unplated brass that tarnishes within weeks, plus undersized O-rings that leak at cold start. Authentic fittings include a factory leak test certificate (showing actual helium leakage value) and a 2‑year / 400,000 km warranty against manufacturing defects or corrosion when installed per guidelines. Store fittings in original sealed bag (below 35°C) and use within 36 months of production date printed on box.
For optimal results, avoid applying the WG9000361307 L-Type Tee Fitting Body Ng8/M12×1.5/Nw6 to ports with damaged threads or heavy rust.
