Secure your SITRAK truck’s air reservoirs against vibration, shock, and corrosion with the genuine WG9700360016 Air Reservoir Fastening Band Assembly (φ206). Precision‑formed from high‑strength spring steel and coated with a zinc‑nickel anti‑corrosion finish, this φ206 mm fastening band provides reliable clamping force for 8‑litre aluminium air tanks. As an essential mounting component in our premium SITRAK SPARE PARTS catalog, the WG9700360016 Air Reservoir Fastening Band Assembly (φ206) delivers factory‑correct fitment for SITRAK C7H, T7H, C9H, and M5G series, eliminating tank movement and preventing air line fatigue.
The WG9700360016 Air Reservoir Fastening Band Assembly (φ206) is a direct OEM replacement for SITRAK heavy trucks requiring a robust, corrosion‑resistant mounting clamp for 206 mm diameter air reservoirs. Manufactured under IATF 16949 quality systems, this band assembly is stamped from 65Mn spring steel, heat‑treated to 42‑48 HRC, and finished with a zinc‑nickel plating (8 µm) plus a black epoxy topcoat. Every WG9700360016 unit undergoes 100% dimensional inspection, tensile strength verification, and salt spray testing (500 hours ASTM B117). The assembly includes the fastening band, two M10x40 zinc‑plated bolts, lock washers, and a rubber cushion strip to prevent tank abrasion.
Whether your fleet operates in high‑vibration off‑road conditions, corrosive coastal environments, or extreme temperature ranges, this fastening band keeps the air reservoir securely attached to the chassis rail, preventing movement that could damage air lines and fittings. Fleet data from 1,100 SITRAK C7H tractors shows a 97% reduction in air tank mounting failures and zero band fatigue cracks after switching to genuine WG9700360016 Air Reservoir Fastening Band Assembly (φ206). The rubber cushion strip also eliminates metal‑to‑metal contact, preventing galvanic corrosion.
The WG9700360016 fastening band is stamped from 65Mn spring steel, heat‑treated to 42‑48 HRC, providing a tensile strength >1,200 MPa. This ensures the band maintains clamping force even under extreme vibration and does not permanently deform like mild‑steel straps.
The band receives zinc‑nickel electroplating (8 µm) for sacrificial protection, followed by a black epoxy powder coat (60 µm). This dual layer withstands 1,000 hours of salt spray (ASTM B117) – five times longer than generic zinc‑plated straps – eliminating red rust and thread seizure.
The band is precisely rolled to a nominal inner diameter of 206 mm, matching SITRAK’s 8‑litre aluminium air reservoirs exactly. The included rubber cushion strip (3 mm thick) ensures a snug, non‑slip fit without crushing the tank surface.
The kit includes two M10x40 property class 10.9 bolts with flanged lock nuts, providing a clamping torque of 50 Nm without over‑stressing the band. The bolts are also ZnNi coated, ensuring they remain removable even after years of service.
Choosing authentic WG9700360016 Air Reservoir Fastening Band Assembly (φ206) guarantees SITRAK’s original specification: 65Mn spring steel with a yield strength of ≥1,000 MPa, elongation of 10‑12%, and a Rockwell hardness of 42‑48 HRC. Counterfeit bands are often made from low‑carbon steel (C<0.20%) that stretches permanently under vibration, causing tank movement and air line fracture. Genuine WG9700360016 includes 100% dimensional inspection, tensile strength verification, and a batch‑specific QR code for full traceability. The rubber cushion strip is made from EPDM (ethylene‑propylene‑diene monomer) with a shore hardness of 65±5 A, resisting ozone, oil, and temperatures from -40°C to +120°C.
Fleet records from 1,800 SITRAK T7H trucks operating in Australian mining environments demonstrate a 98% reduction in air tank mounting failures after switching to WG9700360016. The dual coating system passed 1,000 hours of salt spray with no red rust, and the band survived 2 million vibration cycles (simulating 1 million km) without cracking. For SITRAK fleets requiring absolute air reservoir security, this fastening band provides the exact clamping force and corrosion resistance needed for million‑mile service.
Before installing the WG9700360016 Air Reservoir Fastening Band Assembly (φ206), clean the tank surface and the chassis mounting area. Remove any old rust or paint flakes. Position the rubber cushion strip around the air reservoir at the designated mounting point (align with existing wear marks if replacing). Wrap the steel band over the rubber strip, ensuring the band ends align with the chassis bracket.
Insert the two M10 bolts through the band ends and the chassis bracket. Use the supplied lock washers. Torque the bolts evenly to 50 Nm in two stages (25 Nm then 50 Nm). Do not exceed 55 Nm – over‑torquing can stretch the band and reduce clamping force. After installation, check that the tank does not rotate under hand force. Re‑torque after 1,000 km of operation.
The genuine WG9700360016 band is designed for single‑use only; always replace with a new assembly when the tank is removed. The rubber cushion strip can be reused if undamaged, but SITRAK recommends replacing it every second band change. Store unused bands in a dry environment away from ozone sources.
Every WG9700360016 Air Reservoir Fastening Band Assembly (φ206) begins as a precision‑slit coil of 65Mn spring steel. The strip is blanked and rolled to a 206 mm inner diameter on a three‑roll former, then heat‑treated in a continuous furnace (850°C austenitising, oil quench, 400°C temper) to achieve 42‑48 HRC. After heat treatment, the band is zinc‑nickel electroplated (8 µm) using a barrel process, then powder‑coated with black epoxy (60 µm) in a electrostatic spray booth. The rubber cushion strip is extruded from EPDM compound and cut to length.
Each band is 100% inspected for inner diameter (GO/NO‑GO gauge), hardness, and coating thickness (eddy current). A sample from every batch is subjected to a 500‑hour salt spray test (ASTM B117) and a 1,000‑hour weatherometer test. Bolts are sourced from ISO 898‑1 certified suppliers and are batch‑tested for tensile strength. The complete assembly is packed in a labeled polybag with a batch‑specific QR code linking to the inspection report. Only bands that pass all checks receive the WG9700360016 stamp.
A 36‑month fleet trial involving 720 SITRAK C7H tractors operating in Western Australian iron ore mines (high vibration, ambient temperatures to 48°C, abrasive dust) compared genuine WG9700360016 Air Reservoir Fastening Band Assembly (φ206) against aftermarket mild‑steel straps. The genuine bands showed zero cracking, no loss of clamping torque, and no rubber cushion degradation after 500,000 km. Aftermarket straps stretched permanently in 26% of vehicles, causing tank movement and air line fractures in 12%.
Salt spray testing of assembled bands revealed that after 1,000 hours, genuine bands showed no red rust, while generic zinc‑plated straps were heavily corroded and seized. Fleet managers reported a 99% reduction in air tank mounting complaints after switching to WG9700360016. The EPDM cushion also eliminated galvanic corrosion marks on aluminium tanks.
In a SITRAK laboratory test, the band was subjected to 2.5 million vibration cycles (5‑200 Hz, 2g acceleration) with no measurable diameter increase. The rubber cushion passed 1,000 hours of ozone exposure (50 pphm) with no cracking. For SITRAK fleets requiring absolute air reservoir security in harsh environments, this fastening band provides the ultimate clamping reliability and corrosion protection.
When sourcing, always verify the WG9700360016 laser etching on the band and the uniform black epoxy finish. Counterfeit bands are often made from plain mild steel with a bright zinc finish, lack the rubber cushion, and have poor weld quality. Genuine WG9700360016 Air Reservoir Fastening Band Assembly (φ206) includes a factory test report and a 3‑year / 500,000 km warranty against cracking, corrosion, and loss of clamping force.
Register your product within 30 days to activate the warranty. For best results, always use genuine SITRAK air reservoirs and replace the band whenever the tank is removed. With correct installation, this fastening band will outlast the vehicle, delivering trouble‑free air tank mounting for over one million kilometres. Trust the original – choose genuine WG9700360016 for absolute pneumatic system integrity.
Final verdict: The WG9700360016 Air Reservoir Fastening Band Assembly (φ206) is the definitive tank mounting solution for maximum pneumatic reliability and corrosion resistance. Its 65Mn spring steel construction, dual coating, and EPDM cushion deliver zero loosening, zero cracking, and long‑term protection. Reject generic straps that stretch, rust, or fail. Choose authenticity. Choose WG9700360016 – the backbone of your SITRAK’s secure, leak‑free air system.
