Water Hose
This is a critical component connecting the engine cylinder block and the throttle chamber. It utilizes heat generated from the cylinder block to warm the intake air and circulates the cooled coolant back to the cylinder block, facilitating efficient engine thermal management.

Function
Structure
Inner Rubber + Reinforcement + Outer Rubber
Material
- EPDM
- VMQ
Dimensions
Inner Diameter (I.D.): Ø7 – Ø15
Features
- Excellent Heat Resistance
To withstand the engine's high operating temperatures and continuous exposure to hot coolant, special materials such as EPDM (Ethylene Propylene Diene Monomer) and VMQ (Silicone Rubber) are utilized. These materials resist hardening and deformation even at high temperatures, ensuring stable long-term performance.
- High Durability
Constructed with a triple-layer structure (Inner Rubber + Reinforcement + Outer Rubber) to endure engine room vibrations and pressure fluctuations. The reinforcement layer enhances pressure resistance to prevent expansion or bursting, while protecting the hose from external impacts.
- Versatile Specifications
Manufactured in a wide range of dimensions with inner diameters from Ø7mm to Ø15mm, making them applicable to various vehicle models and engine specifications.
- Precise Fluid Circulation
Ensures optimal fluid flow for smooth coolant circulation between the cylinder block and the throttle chamber, thereby maximizing engine performance.
