Can I Use Silicone to Coat Automotive Hoses
This is a question we know gets asked often. Can you lot 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 forbid oil from penetrating the wall just we would not recommend these for Fuel lines, or heavy use of Fuel Filling. Occasional fuel usage and vapour will be fine only in that location are better options when it comes to selecting fuel hoses:
Options for fuel hoses:
2 materials, which are better suited for fuel hose applications, are Nitrile Rubber and PTFE.
Nitrile rubber (NBR) is an oil-resistant synthetic rubber. Its master applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required. Hither at Viper we sell diverse products which apply Nitrile Safe. These are:
• SAE J30 R6 approved Nitrile Safety 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 Safe lining and are perfect for using as a Fuel Filler Hose. These hoses are non Suitable for loftier 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 improvidence of automotive fuels, in comparing with all other plastics and rubbers. We have summit Quality Stainless Steel Braided hose available lined with PTFE. The force per unit area rating makes it suitable for use equally Restriction Lines, Clutch Lines, Oil and fuel.
