3/8in (10mm) I.D. x 10ft Silicone Vacuum Hose

The VIBRANT PERFORMANCE 3/8-inch (10mm) I.D. x 10-foot silicone vacuum hose is essential plumbing for any serious engine modification or emissions system upgrade. Whether you're reconfiguring a carbureted build, installing a turbo system, or rerouting factory vacuum lines for a custom intake manifold, this hose delivers the reliability needed when OEM tubing fails or incompatible sizing becomes a bottleneck.

This hose features premium silicone construction, which outperforms standard rubber in heat resistance, UV stability, and longevity under underhood extremes. The 3/8-inch (10mm) inner diameter fits mid-range vacuum circuits—typical for distributor advance lines, PCV systems, and small-displacement intake manifold applications. At 10 feet in length, you'll have ample material for complex routing without excessive splicing, and silicone's flexibility allows tight bends around engine bay obstacles.

Unlike brittle OEM rubber that hardens and cracks over time, Vibrant's silicone maintains elasticity through repeated thermal cycles, ensuring consistent vacuum integrity season after season. Mechanics and enthusiasts upgrading carburetors, rebuilding vacuum-dependent brake systems, or transitioning to standalone EFI systems rely on this hose for its compatibility across vintage muscle cars and modern builds alike.
