Silicone Hose & Fittings

High performance vehicles demand components that can handle extreme conditions without compromise. Our silicone hoses and fittings are designed to meet that challenge, providing exceptional durability, flexibility, and reliability for a wide range of automotive and motorsport applications.

Important Compatibility Notice:

Silicone rubber is not resistant to gasoline, diesel, oil, ethanol blends, or most hydrocarbons. Gasoline, diesel, ethanol blends, and even fuel vapors will permeate through silicone, causing it to swell, soften, and eventually break down. Over time, this can lead to leaks, hose failure, or engine damage. For any fuel or oil transfer applications, we recommend using hoses specifically designed for chemical resistance.

Common Automotive Uses for Silicone Hose:

  • Coolant Systems
    • Radiator hoses, heater core lines, bypass lines, and overflow tanks.
    • Silicone’s heat resistance (up to ~350°F / 175°C) makes it ideal for engine coolant circulation, and it does not degrade with antifreeze or water like rubber sometimes does.
  • Air Intake & Turbo Systems
    • Intake couplers, charge pipes, intercooler connections, and boost lines.
    • Handles high air temperatures and pressures without softening, with great flexibility for vibration and movement between components.
  • Vacuum Lines
    • Excellent for manifold vacuum, boost control, emissions, or PCV systems that do not involve oil or fuel directly.
    • Stable under vacuum and resists cracking over time.
  • Crankcase Ventilation/Breather Hoses
    • Suitable if there is vapor exposure but not liquid oil or fuel contact.
    • Common in custom catch-can setups or PCV rerouting.
  • Heater and HVAC Systems
    • Used for defroster and climate control air ducts, and handles temperature swings and ozone exposure well.

Built to withstand intense heat and high pressure, our silicone hoses outperform traditional rubber alternatives for these specified systems. They maintain their shape under vacuum, resist collapsing, and offer superior thermal insulation, ensuring consistent airflow, reduced heat soak, and dependable performance for street, track, or off-road environments.

Our selection includes straight couplers, reducers, hump hoses, tight radius bends, elbows, and vacuum lines, ideal for intake systems, intercooler piping, turbocharger connections, and custom fabrication projects. With a range of diameters, wall thicknesses, and lengths, it is easy to find the right fit for any non-fuel, non-oil setup.

Precision-engineered fittings and couplings ensure secure, leak-free connections and a professional installation that holds up under pressure while providing a clean, finished look. For custom builds, silicone hose sold by the foot offers the flexibility to cut exact lengths for tailored solutions.

Accessories such as clamps, brackets, and adapters make installation straightforward and reliable. Every connection is reinforced and stable, even in high-vibration or high-temperature environments.

Choosing silicone hoses and fittings means investing in components that last longer, perform better, and look sharper under the hood. Trusted by professional builders and enthusiasts who demand consistent results in demanding conditions, our hoses and precision fittings provide the foundation for proven performance, as long as they are used within their recommended applications.
