1203040-1522 High Temperature Metal Flexible Hose Assembly Shock Absorption Exhaust Pipe For Sinotruk Heavy Truck

Product Overview

1203040-1522 metal flexible hose assembly is an essential connecting pipeline component matched for Sinotruk full series heavy-duty trucks. It is installed between engine exhaust outlet and rear exhaust pipeline, acting as elastic buffer connector. This flexible metal hose absorbs strong vibration generated by engine operation, offset assembly installation deviation and thermal expansion deformation. It solves common pipeline faults such as exhaust pipe fracture, air leakage, flange crack and abnormal exhaust noise caused by rigid pipeline hard connection, ensuring smooth exhaust emission for long-distance transport vehicles.

Core Product Advantages

1. Double-layer stainless steel braided outer mesh + seamless inner tube integrated forming, strong tensile and bending resistance, not easy to break under long-term bumpy road vibration.

2. Ultra-high temperature resistant metal material, stably bear high exhaust temperature, no softening, deformation or air leakage under continuous full-load climbing operation.

3. Integrated thickened flange joint, precision laser welding technology, firm welding seam without air hole, effectively block exhaust gas leakage and reduce exhaust noise.

4. Excellent anti-corrosion performance, resist erosion of rainwater, road salt, diesel and exhaust condensate, suitable for humid, coastal and dusty construction site environments.

5. Strong shock absorption and displacement compensation capacity, buffer engine resonance and thermal expansion, reduce stress damage to exhaust pipeline and related brackets.

6. Standard flange hole spacing and pipeline overall length, fully match Sinotruk exhaust system mounting position, plug-and-play without cutting, welding or pipeline adjustment.

7. Strict air tightness and vibration fatigue test before delivery, stable batch quality, suitable for repair shop replacement and logistics fleet bulk procurement.
