Collection: Silicone Vacuum Hose

High-Performance Silicone Vacuum Hose for Demanding Applications

Upgrade from brittle rubber vacuum lines to premium silicone vacuum hose that won't crack, split, or perish under heat and pressure. Our silicone vacuum hoses are engineered for performance engines, turbo systems, and custom builds where reliability is critical.

Why Choose Silicone Over Rubber?

Standard rubber vacuum hoses deteriorate quickly in high-temperature engine bays, leading to vacuum leaks, rough idle, poor performance, and failed emissions tests. Silicone vacuum hose is rated to 150°C (compared to rubber's 80°C limit), resists oil and coolant contamination, and maintains flexibility even after years of heat cycling. This means fewer vacuum leaks, better engine performance, and a cleaner, more professional-looking engine bay.

Key Benefits:

• Heat Resistant to 150°C: Won't crack or harden in hot engine bays, perfect for turbo and supercharged applications
• Reinforced Construction: Multi-ply silicone with polyester reinforcement prevents collapse under vacuum
• Oil & Coolant Resistant: Won't deteriorate from exposure to automotive fluids
• Vibrant Colours Available: Blue, red, black options for a custom appearance
• Multiple Sizes: Full range of internal diameters from 3mm to 25mm to suit any application
• Flexible & Durable: Maintains flexibility through extreme temperature cycles

Common Applications:

• Turbocharger and supercharger vacuum lines
• Brake booster vacuum connections
• PCV (Positive Crankcase Ventilation) systems
• Intake manifold vacuum ports
• Boost control solenoid plumbing
• Wastegate actuator lines
• Fuel pressure regulator vacuum reference
• Custom engine builds and restorations

Available Sizes:

We stock a comprehensive range of internal diameters including 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 19mm, and 25mm. Available in straight lengths, 90-degree elbows, 45-degree elbows, reducers, and T-pieces to suit any vacuum routing requirement.
