Material Description: Silicone performs well in a wide range of temperatures -- from extremely low to moderately high -- and is excellent in Air applications. It is also compatible with Engine Oil. It has limited strength and abrasion/cut resistance, so it is better in low pressure applications. Silicone should not be used with Diesel Fuel, Coolant/Urea, Hydraulic Oil, Automatic Transmission Fluid or Biodiesel. Notes: Dimensions and Material Descriptions provided for reference only.
