Introduction

This is a high-quality OEM-standard exhaust flexible hose specially designed for SINOTRUK heavy-duty trucks, fully compatible with HOWO, T5G, T7H and Sitrak series models. Serving as a key flexible connection part of the truck exhaust system, it effectively connects exhaust pipes and mufflers, absorbing engine vibration and road shock while exhausting waste gas smoothly. It solves common problems such as exhaust pipe cracking, air leakage and abnormal noise caused by rigid connection vibration. Manufactured in strict accordance with original factory specifications, it features precise size and 100% interchangeability, suitable for various SINOTRUK tractors, dump trucks, water tank trucks and engineering trucks, widely exported to Africa, Middle East and Southeast Asian heavy truck aftermarket markets.

Key Features

✅ 1. Exact OEM Standard, Perfect Direct Replacement

Produced strictly following the original OEM parameter WG9727549088. The overall length, caliber, connection interface and installation hole position are completely consistent with original parts. No cutting, welding or modification is required during installation, supporting fast plug-and-play replacement. It perfectly matches all applicable SINOTRUK heavy truck models with zero installation mismatch.

✅ 2. Excellent Vibration Isolation & Anti-Crack Performance

Adopts professional multi-layer flexible woven structure, which can effectively buffer high-frequency vibration generated by engine operation and bumpy road driving. It greatly reduces the rigid tension of the exhaust pipeline, fundamentally avoids pipe body fracture and interface cracking, and stabilizes the overall structural tightness of the exhaust system for long-term heavy-duty operation.

✅ 3. High Temperature & Exhaust Corrosion Resistance

Made of high-grade heat-resistant stainless steel and reinforced braided layer, the hose can withstand long-term high-temperature exhaust impact without deformation, oxidation or damage. It resists corrosion from exhaust gas and chemical sediments, maintains stable structural performance in high-temperature working environments, and avoids exhaust leakage failure caused by high-temperature aging.

✅ 4. Zero Exhaust Leakage, Optimize Vehicle Performance

Precision integrated forming process ensures tight sealing at the connection ends. It effectively prevents exhaust gas leakage, eliminates exhaust noise and abnormal air leakage sound, ensures smooth and unobstructed exhaust emission, and maintains normal engine power output and fuel economy, avoiding power drop caused by poor exhaust.

✅ 5. Strong Adaptability to Harsh Working Conditions

The flexible hose features outstanding structural toughness and fatigue resistance, adapting to complex working scenarios such as mining bumpy roads, long-distance highway transportation and tropical high-temperature dusty environments. It is not easy to loose or damage under frequent vibration and alternating load, with low failure rate and strong environmental adaptability.

✅ 6. Strict Quality Inspection & Cost-Effective Wholesale Supply

Every flexible hose passes strict air tightness test, high-temperature endurance test and vibration fatigue test before delivery to ensure stable and reliable quality. With factory direct sales price and sufficient inventory, it supports sample orders and large batch wholesale, meeting the procurement needs of global truck repair shops, spare parts dealers and fleet companies.
