Product Overview
High-Performance Silicone Vacuum Hoses are engineered for ultimate reliability in high-temperature and high-vacuum environments. Manufactured from 100% premium virgin silicone rubber, these hoses are designed to withstand extreme thermal fluctuations without hardening, cracking, or collapsing.
Specifically developed for automotive turbocharger systems, racing engines, and industrial vacuum lines, our silicone hoses offer superior flexibility and durability compared to standard rubber tubing. They are the ideal choice for air intake connections, wastegate actuators, and coolant overflow systems.
Structure & Cross-Section
 |
Multi-Layer Extrusion for Maximum StabilityOur vacuum hoses feature a precision-extruded uniform wall thickness that ensures consistent performance across the entire length of the tube. For high-pressure applications, we offer reinforced versions with integrated polyester or aramid braiding to prevent expansion under boost. The smooth inner bore minimizes airflow turbulence, while the glossy outer finish provides excellent resistance to UV, ozone, and engine bay contaminants. |

FAQ – Request For Quotation (RFQ)
❓ How do I specify dimensions for an RFQ?
Please provide the Inner Diameter (ID), Wall Thickness, and the total length needed. If you require reinforced hoses, please specify the working pressure requirement.
❓ Are your silicone hoses oil-resistant?
Standard silicone is resistant to oil mist but not permanent oil submersion. For fuel or direct oil contact, we recommend our specialized Fluorosilicone-lined hoses.
❓ Can you produce custom lengths or kitted sets?
Yes. We can provide continuous lengths on spools or pre-cut pieces in kitted sets for specific vehicle models or industrial assemblies.
❓ What is the turnaround time for a custom quote?
Our engineering team typically provides a detailed technical quotation within 12-24 hours of receiving your specifications.
