Description

Blue Silicone Vacuum Hose is a flexible, high-temperature hose designed for vacuum, breather, and low-pressure applications in automotive, motorsport, and industrial environments. Manufactured by AutoSiliconeHoses from premium VMQ silicone, it provides excellent resistance to heat, ozone, and weathering, ensuring reliable performance in demanding conditions. The lightweight construction offers flexibility and ease of installation, while the vibrant blue finish allows quick identification in multi-line systems or customised engine bays. With an operating temperature range of -60°C to +180°C (peak +200°C) and compliant with SAEJ20R3 standards, this hose is engineered for durability and consistent service life.

Key Features:

Material: VMQ silicone inner and outer layers.
Internal Diameter Range: 2 mm to 10 mm.
Wall Thickness: 1 mm to 3 mm depending on size.
Working Pressure: Atmospheric vacuum (not pressure rated).
Temperature Range: -60°C to +180°C continuous; +200°C peak.
Standard: SAEJ20R3 compliant.
Colour: Blue for easy line identification and styling.
Brand: AutoSiliconeHoses performance silicone.

Blue silicone vacuum hose combines flexibility and temperature resistance to perform reliably in vacuum and breather applications. The smooth bore ensures unrestricted flow while the durable silicone walls provide resilience against cracking, hardening, or deterioration over time. Designed for routing around tight bends and confined spaces, it is well-suited for engine bays and other environments subject to high temperatures and vibration. Its bright blue finish not only aids line identification but also enhances the appearance of performance setups.

Applications include vacuum lines, breather hoses, washer tubing, and low-pressure connections in automotive, motorsport, and light industrial systems. Distributed under the AutoSiliconeHoses brand, the blue silicone vacuum hose offers a cost-effective, flexible, and long-lasting solution for low-pressure and atmospheric vacuum duties where high temperature and environmental resistance are required.
