Use: DOT 5 Silicone Brake Fluid (DOT V) is a silicone-based (Polydimethysiloxane CAS# 63148-62-9) fluid that is formulated specifically for used in hydraulic brake systems to provide corrosioin protection and lubrication. DOT 5 Silicone Brake Fluid is recognizable by its bluish-purplish color. In comparison to DOT 3 & DOT 4 Brake Fluids, DOT 5 provides higher thermal stability and higher dry and wet boiling points. In addition, being silicone-based, DOT 5 is hydrophobic and will not absorb water.

DOT 5 has a service temperature range of -55°C to 55°C. Its dry boiling point (no water present) is 260°C and its wet boiling point (contains 3% water) is 180°C Due to these properties, DOT 5 Silicone Brake Fluid is widely used by the military. It meets Mil-PRF-46176 & Mil-PRF-46176B. DOT 5 Brake Fluid also meets SAE J 1705 Society of Engineers.

DOT 5 Silicone Brake Fluid is compatible with a wide range of brake materials including SBR, EP, Neoprene and Natural Ruber.
