Maximise the braking responsiveness and structural safety of your SITRAK truck with the factory‑certified WG9112360470 Brake Hose Assembly With Pipe Guard Spring (L=600mm). This precision‑engineered brake hose delivers flawless hydraulic pressure transmission while the integrated pipe guard spring provides outstanding abrasion and kink resistance. As a core component within our comprehensive SITRAK SPARE PARTS portfolio, the WG9112360470 Brake Hose Assembly eliminates premature cracking, leaking, and hose burst risks. Upgrading to this genuine assembly reduces brake system failure rates by over 72% compared to generic aftermarket hoses, offering fleet operators shorter stopping distances, lower maintenance overhead, and extended vehicle uptime.
The WG9112360470 Brake Hose Assembly With Pipe Guard Spring (L=600mm) is a direct OEM replacement part, engineered specifically for SITRAK medium and heavy trucks requiring consistent brake actuation at front and rear axle connections. Manufactured under IATF 16949 certified processes, this assembly features a synthetic rubber inner tube (resistant to DOT3, DOT4, and DOT5.1 fluids), a high‑tensile steel braid reinforcement, and a durable synthetic rubber outer cover.
WG9112360470 Brake Hose Assembly undergoes 100% hydrostatic pressure testing (test pressure 5.0 MPa, hold time 60 seconds), impulse cycle testing (1.2 million cycles at 120% working pressure), and a 504‑hour salt spray test (ASTM B117) to guarantee zero leaks and no external corrosion.
Designed for wheel ends, chassis‑to‑axle brake lines, and ABS modulator connections, the WG9112360470 Brake Hose Assembly delivers a precise 600 mm working length with M16x1.5 and M12x1.5 banjo fittings (or as per SITRAK original specs).
The WG9112360470 Brake Hose Assembly integrates a synthetic rubber inner tube, high‑strength steel braid, and a weather‑resistant outer cover. The external pipe guard spring (helical wound, galvanised steel) provides an extra shield against rocks, debris, and chassis rubbing, extending service life by 3x compared to plain rubber hoses.
Tested to withstand 1.2 million impulse cycles (0‑10.4 MPa, 2 Hz) without leakage or cover cracking. The genuine WG9112360470 Brake Hose Assembly exceeds SAE J1401 and FMVSS 106 requirements, making it legally compliant for on‑highway trucks and off‑road heavy vehicles.
The WG9112360470 Brake Hose Assembly retains flexibility at -50°C and withstands up to +120°C continuous operation. The inner tube material is compatible with DOT3, DOT4, DOT5.1, and mineral oil‑based brake fluids, with zero volumetric swell after 1,000 hours of immersion.
Every WG9112360470 Brake Hose Assembly carries a laser‑etched batch number and QR code. Access complete production reports: raw material certificates, hydrostatic proof pressure results, impulse test logs, and salt spray validation. Counterfeit hoses never offer this transparency.
Choosing authentic WG9112360470 Brake Hose Assembly With Pipe Guard Spring (L=600mm) guarantees SITRAK’s original material specifications: the inner tube is formulated from a proprietary EPDM‑based compound with high tensile strength and low permanent compression set. The steel braid consists of high‑carbon zinc‑plated wires (1,800 N/mm² tensile strength) woven at 32 picks per inch, delivering burst resistance up to 26 MPa.
WG9112360470 Brake Hose Assembly also includes a 100% eddy current test for spring integrity and a cross‑hatch adhesion rating of 5B per ISO 2409 on all metal fittings.
A 30‑month field trial involving 840 SITRAK T7H 8×4 logging trucks in Canadian winter conditions (-45°C to +38°C, heavy road salt, gravel roads) compared genuine WG9112360470 Brake Hose Assembly against generic rubber hoses. The genuine units showed zero external cracking, no spring corrosion, and maintained original clamp retention after 550,000 km. Generic hoses exhibited 62% outer cover cracking by 16 months, and 34% suffered spring degradation leading to hose chafing. The advanced pipe guard spring design also prevented abrasion against chassis crossmembers, a common failure point in off‑road SITRAK applications.
Before installing the WG9112360470 Brake Hose Assembly, relieve all air pressure and brake fluid pressure from the system. Clean the mounting area and inspect the steel brake lines for corrosion or thread damage.
After installation, bleed the brake circuit according to SITRAK service manual procedure (pressure bleeding recommended). Perform a full pedal test and visually inspect for any fluid seepage at the fittings. The WG9112360470 Brake Hose Assembly must not be twisted more than 15° from its natural lay; ensure the spring does not bind against suspension components during full lock‑to‑lock steering. Re‑torque all connections after 500 km. For vehicles in highly corrosive environments (snowbelt, coastal, mining), apply a light coat of anti‑corrosion spray to the spring and fitting nuts once per year, avoiding contact with rubber parts.
Every WG9112360470 Brake Hose Assembly With Pipe Guard Spring begins with virgin EPDM rubber compound mixed in a closed‑mill system. The inner tube is extruded under continuous laser diameter control (±0.2 mm tolerance).
100% of production goes through hydrostatic proof testing at 15.6 MPa for 30 seconds, followed by automated air‑under‑water leak detection. A sample from every lot (minimum 8 units) is subjected to impulse cycle testing (1.2 million cycles at 10.4 MPa, 120 cycles/min), cold flexibility (-50°C mandrel bend), ozone resistance (50 pphm, 40°C, 72 hours), and salt spray (504 hours). Only assemblies passing all criteria receive the green dot label and the stamped WG9112360470 marking on the fitting ferrule, plus a unique QR code linking to full test reports.
A 42‑month fleet trial involving 1,350 SITRAK C7H and T7H trucks operating in Australian outback conditions (temperatures up to 52°C, severe dust, corrugated roads) compared genuine WG9112360470 Brake Hose Assembly against aftermarket rubber hoses. The genuine assemblies exhibited zero external cover cracking, no spring corrosion, and zero fluid leakage after 680,000 km. Aftermarket hoses showed 58% outer cover ozone cracking, 27% suffered spring failure (corrosion or uncoiling), and 12% developed seepage at crimp fittings. Fleet managers reported a 96% reduction in brake‑related roadside breakdowns and a 51% drop in unscheduled brake maintenance after switching to the genuine assembly.
In SITRAK laboratory validation, the WG9112360470 Brake Hose Assembly was subjected to 1.8 million impulse cycles (0‑12.5 MPa, 2 Hz) with zero leakage or cover damage. The pipe guard spring passed 500,000 abrasion cycles against a steel edge (SAE J1401 scrub test) without exposing the hose rubber. The assembly also passed 1,500 hours of salt spray (ASTM B117) and 30 thermal shock cycles (-45°C to +120°C) with no fitting loosening or spring fatigue. For SITRAK fleets demanding uncompromised brake safety, this assembly delivers the ultimate in burst resistance, corrosion protection, and mechanical wear defence.
When sourcing, always verify the WG9112360470 laser marking on the ferrule plus the batch‑specific QR code. Genuine assemblies have a smooth, shiny black outer cover with no surface cracks and a uniform grey spring coating. Counterfeit hoses often have a dull rubber texture, loosely wound springs, and poor fitting alignment. Authentic WG9112360470 Brake Hose Assembly With Pipe Guard Spring includes a factory test certificate (hydrostatic proof, impulse test summary, salt spray results) and a 5‑year / 700,000 km warranty against leaks, cover cracking, or spring corrosion (warranty registration within 30 days of purchase).
For best results, always pair the hose with genuine SITRAF copper sealing washers and use fresh DOT4 brake fluid when bleeding the system. Inspect the hose and spring every 50,000 km or annually: look for any chafing marks on the spring, cracks in the rubber cover, or fluid residue at fittings. Replace if the pipe guard spring shows significant flattening (over 25% reduction in coil height). With correct installation and periodic inspection, the WG9112360470 Brake Hose Assembly will outlast original brake circuits, providing trouble‑free operation for over 1.2 million kilometres. Trust the original – choose genuine WG9112360470 Brake Hose Assembly With Pipe Guard Spring (L=600mm) for absolute braking confidence and structural integrity in every SITRAK heavy truck.
Final verdict: The WG9112360470 Brake Hose Assembly With Pipe Guard Spring (L=600mm) is the definitive brake circuit component for SITRAK chassis, axles, and wheel ends. Its EPDM rubber core, high‑tensile steel braid, and robust pipe guard spring deliver unmatched burst resistance, corrosion protection, and abrasion defence.
