Silicone Hoses

Universal silicone hoses for cooling, turbo, intercooler, and vacuum systems. All SFS Performance hoses are rated from −50 °C to 180 °C with 3-ply polyester reinforcement and a 4.5 mm wall.

Not suitable for fuel or oil.

How to Select the Correct Hose

Measure the outside diameter of the pipe spigot or barb you are connecting to. Choose a hose whose internal diameter (ID) matches that measurement. Silicone stretches slightly — a hose 2–3 mm smaller in ID will also seal correctly on a barb when clamped.

For a direction change, use an elbow (45° or 90°). To connect two pipes of different diameters, use a reducer hose. To connect two pipes of different diameters at a right angle, use a 90° elbow reducer.

Suitable Applications

• Engine coolant hoses (radiator, heater circuit, expansion tank)
• Turbocharger compressor outlet hose
• Intercooler charge air pipes
• Air intake hose (air filter to throttle body)
• Crankcase breather hoses
• Blow-off valve (BOV) inlet hose
• Wastegate actuator lines

FAQ

Can these hoses be used for fuel lines?

No. Silicone is not resistant to petrol, diesel, or oil. Use PTFE-lined hose for any fuel or oil application.

Are these vehicle-specific or universal?

Universal. No vehicle-specific kits are included. Measure your existing hose internal diameter before ordering.

What clamps should I use?

Worm-drive (jubilee) or T-bolt clamps. T-bolt clamps apply a more even seating force and are preferred for charge air applications. Position the clamp 10–15 mm from the end of the hose.

How do I know which angle I need?

Use a straight hose where the pipes are parallel and the hose can flex freely. Use a 45° elbow where there is a moderate direction change. Use a 90° elbow where a sharp corner is needed. Reducer elbows both change direction and transition between two pipe sizes in one piece.

What is the difference between the Samco Xtreme hump hose and the SFS hoses?

The Samco Xtreme hump hose is rated to 250 °C compared to 180 °C for SFS Performance hoses. It also has a moulded central hump that absorbs vibration and thermal expansion between two rigid pipes. Use it where a standard straight coupler would transmit engine vibration or crack under heat cycling.
