This is a question we know gets asked often. Can you use silicone hoses for fuel hoses? Well standard silicone hoses are porous and therefore not suitable for oil or fuel. There are flurosilicone liners, which are specially formulated to prevent oil from penetrating the wall but we would not recommend these for Fuel lines, or heavy use of Fuel Filling. Occasional fuel usage and vapour will be fine but there are better options when it comes to selecting fuel hoses:
Options for fuel hoses:
Two materials, which are better suited for fuel hose applications, are Nitrile Rubber and PTFE.
Nitrile rubber (NBR) is an oil-resistant synthetic rubber. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required. Here at Viper we sell various products which utilise Nitrile Rubber. These are:
• SAE J30 R6 approved Nitrile Rubber fuel Hose – this fuel hose is fully compliant with SVA regulation and most types of fuel.
• Fuel Filler Hose – These hoses are made with a fuel resistant Nitrile Rubber lining and are perfect for using as a Fuel Filler Hose. These hoses are not Suitable for high octane fuels.
• Stainless Steel Braided Hoses – Superb Quality Stainless Steel Braided hose with tight double braiding and NBR offers a good bend radius, and high pressure use for Oil, fuel lines, Carburetor, water lines, vacuum.
PTFE or Polytetrafluoroethylene lined hoses can be used for a wide variety of chemicals, making it the ideal choice for very corrosive chemical applications and multiproduct applications. In some cases, PTFE has superior resistance to diffusion, for example to the diffusion of automotive fuels, in comparison with all other plastics and rubbers. We have top Quality Stainless Steel Braided hose available lined with PTFE. The pressure rating makes it suitable for use as Brake Lines, Clutch Lines, Oil and fuel.
