Coolant, Heater, and Radiator Silicone Hose Supplier
Automotive Silicone Hoses Manufacturer
Automotive silicone hoses are widely used in modern vehicle systems where heat resistance, pressure stability and flexible routing are required beyond the limits of conventional rubber hoses.
As a manufacturer and supplier, Suconvey produces a full range of automotive silicone hoses, including straight hoses and formed elbow hoses, designed to fit real engine layouts and installation constraints.
Our production covers silicone turbo hoses, intercooler hoses, radiator hoses, heater hoses and cooling hoses, available in multiple standard bend angles or fully customized shapes to match your application.
Automotive Silicone Hoses
Automotive silicone hoses are flexible elastomer hoses made from high-temperature silicone rubber, used to transport air or coolant within vehicle systems.
Compared with EPDM or standard rubber hoses, silicone hoses offer:
- better resistance to heat and thermal cycling
- improved flexibility over long service life
- stable performance under pressure and vibration
- reduced risk of cracking or hardening
These advantages make silicone hoses a preferred solution for turbocharged engines, cooling circuits and heater systems.

Customized Silicone Turbo & Intercooler Hoses Supplier
Hose Shapes Designed for Real Vehicle Layouts
One of the key challenges in automotive hose selection is routing. Engine bays are compact, crowded and subject to movement and vibration. Hose shape matters as much as material.
Straight Silicone Reducer: Straight hoses are commonly used where alignment is simple and space allows direct routing.
Elbow Silicone Hoses: Elbow hoses are designed to redirect flow and adapt to tight spaces without kinking. We manufacture formed silicone elbows in common bend angles, including:
- 45-degree silicone hoses for gentle directional changes
- 90-degree silicone hoses for compact right-angle routing
- 135-degree silicone hoses for complex engine layouts
Formed elbows reduce stress on hose connections and help maintain smooth airflow or coolant flow.

Key Automotive Hose Types We Supply
Turbo & Intercooler Hoses
Turbo and intercooler hoses must handle elevated temperatures, boost pressure and vibration. Reinforced silicone turbo hoses and intercooler hoses maintain shape under pressure and are available in straight and elbow configurations to suit different charge-air paths.
Radiator & Cooling Hoses
Radiator hoses and cooling hoses are critical to engine temperature control. Silicone cooling hoses remain flexible and reliable even after prolonged exposure to hot coolant and repeated heat cycles, making them suitable for both straight runs and tight bends.
Heater Hoses
Heater hoses route hot coolant between the engine and cabin heating system. Silicone heater hoses resist aging and hardening, supporting consistent flow and sealing over time.
Why Automotive Customers Choose Silicone Hoses
Designed for Heat and Thermal Cycling
Silicone rubber maintains flexibility and mechanical integrity across a wide temperature range, making it well suited for under-hood environments.
Shape Accuracy and Dimensional Stability
Formed silicone elbows are molded to precise angles, helping ensure proper fit, reduced installation stress and consistent routing.
Pressure and Vibration Resistance
Multi-ply reinforced constructions reduce expansion under pressure and absorb vibration, protecting hose connections and surrounding components.
Clean Installation and Long Service Life
Silicone hoses offer a smooth finish and consistent wall thickness, contributing to both performance reliability and a clean engine bay appearance.

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone tubes are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.
Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test tubes can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.
After-Arrival Support
If any damage or discrepancies are discovered during unloading or inspection, customers may contact us within 7 days with photos and batch information. Our team will respond promptly to assess the situation and provide a reasonable solution.
