Turbo/CAC Applications

Silflex Turbocharger & CAC (charge air cooled) hoses are manufactured in silicone with an Aramid reinforcing fabric as standard, allowing higher temperature & pressure resistance. For more demanding requirements, construction can incorporate wire reinforcing, offering greater resistance to profile changes & improved flexibility respectively. Available in a wide range of configurations and dimensions, Silflex Coolant Hose is manufactured from the highest grade silicone rubber formulated specifically for automotive applications. Superb reliability helps reduce maintenance and down time while providing greater engine protection. A high sheen finish is standard with other options available.


Construction consists of several plies of silicone, reinforced with Aramid fabric. The number of plies will vary depending on the working pressure, bore size, and required wall thickness.

Convoluted Hose is produced to suit most power unit applications. Single or multiple convolution variants are available, providing increased flexibility & the ability to absorb greater levels of engine vibration.

A galvanised steel wire helix can be added, buried between the plies so that it is not exposed on either the inside or outside of the hose, perfect for high or negative pressure applications or where improved flexibility is required. Additionally the hoses can be supplied with either convoluted or castellated walls where needed.

Depending on working temperature, there are various build options available that allow the hose to function properly between -50ºC and 305ºC.

General Use

Silflex turbocharger hose has been specifically designed for the demanding requirements of truck, bus and rail applications. It is primarily designed for use in turbocharger systems. It can however be used in many other applications where the properties of silicone are preferable to those of other rubbers, where a flexible joint is required between rigid pipe work, or where higher working temperatures compared to standard silicone/polyester are required.

Production Volumes

As a result of our unique manufacturing process we are extremely flexible with production volumes. Silflex has a very diverse range of customers and we understand that each requires an individual silicone hose solution. Many specialist customers require low run and prototype orders however others need high volume mass produced parts. We are a self contained unit capable of offering what other companies cannot, a personally tailored service designed to meet our customers needs.

Fuel & Oil Mist

State-of-the-art Fluorosilicone & Profuel® linings are available if there is the possibility of the hose coming in to contact with fuel mist. Silflex Fluorosilicone lined turbocharger hose has been specifically designed for the demanding requirements of truck, bus and rail applications. It is primarily designed for use in turbocharger systems & intercooler systems where the medium flowing through the hose is likely to degrade the standard silicone. e.g. Fuel Oils, Diesel Fuel, etc. This comes in the form of a lining of Black Fluorosilicone, covered with Plies of silicone, reinforced with Aramid fabric.

Standard Parts

Silflex produce a range of standard parts suitable for various coolant applications that are kept in stock. Variations of colour, part marking or specialist linings will require a lead time for production.

Hose elbows are produces to 90°, 45° & 135° bends with reducers to suit diameter changes. Reducers and Couplers enable a smooth flow transition between various components & pipe bore sizes. Silflex coolant hose couplers enable the connection of rigid pipe work to help eliminate vibration, increase flexibility and allow easier assembly and maintenance.

Straight hose lengths provide a flexible link between system pipe work and components. Wire reinforcement & convolutions are also available to avoid kinking due to angles or movement, and can also be manufactured in special materials or formulations.

Engineering Options

Wire Reinforcement

A wire helix between the plies helps to prevent collapse in negative pressure conditions.

Anti Abrasion Sleeves

Anti Abrasion Sleeves to protect against localised abrasion.

Part Marking

Part marking with Silflex or customer logos and part numbers assists with product identification and traceability.

Location Marking

Marks can be added to the hose to specify where components are to be placed such as clips helping speed up installation.
