Earlier this year we wrote a blog answering the question ‘Are Silicone Hoses fuel resistant?’ which has been really popular, but what about oil? Is silicone hose oil resistant?

Standard Silicone rubber is porous and therefore not suitable for oil. Made to order, our Fluoro lined silicone hoses use a specially compounded silicone called FluoroSilicone. This grade is specially formulated to prevent oil from penetrating the wall.

Many of our competitors dilute the material to save money, because the FluoroSilicone material is a very expensive material. This means they cut materials such as 60/40 or even 50/50 mix by adding large quantities of fillers. This of course reduces the resistance to oils. Here at Viper Performance we only use the highest concentration of 80/20 mix of flurosilicone to give you the best possible resistance against oil.

Chemical properties

The chemical properties of FluoroSilicone mean that it provides excellent resistance to hydrocarbons, fuel vapour, mineral and synthetic oils and greases. It is also suitable for use with mineral-based hydraulic fluids.

We would not recommend Fluosilicone for Fuel lines, or heavy use of Fuel Filling. Read our previous blog to find the best products for fuel hoses.

To order

We offer optional FluroSilicone liners with most of our silicone hoses. Simply click the shape hose you need and select “FLUORO” from the build materials list. Please allow just 10-12 days average for Fluoro Lined Hoses.
