Description

The Sasol Brake Fluid DOT 4 brake fluid complies with the National Compulsory Standard Specification for Hydraulic Brake Fluids. Brake Fluid, Automotive, Heavy Duty, Dot 4, Grade 270

Application

  • The DOT 4 product is intended for systems where operating temperatures can rise to above 260°C but will not exceed 270°C
  • The grade number allocated to this product reflects the maximum permissible operating temperature
  • This grade is a heavy duty product and is equally suitable for hydraulic clutch systems where operating temperatures are generally below those in brake systems

Features and Benefits

  • Sasol Brake Fluid DOT 4 is not a mineral oil, but somewhat toxic hydraulic fluids, blended from glycols and selected additives. Skin and eye contact should be avoided. If swallowed obtain medical assistance. Avoid spillage onto vehicle paintwork which can be damaged if left in contact with the product.
  • The fluid is fully compatible with the natural rubber seals of automotive brake systems.
  • The product is hygroscopic (absorb water) and should be replaced annually, especially in coastal areas, to prevent rusting of components and possible brake failure due to water vapour in the system. Containers must be kept tightly sealed.

Storage and Handling

  • Use PVC, nitrile or other product-resistant gloves and protective clothing in cases where frequent or prolonged skin contact cannot be avoided
  • Where eye contact is a potential hazard, goggles or face shields should be worn
  • Respiratory protection is not normally required but if an inhalation risk is present wear a half-mask respirator with an approved organic vapour cartridge and particulate filter
  • Avoid elevated temperatures exceeding 100°C and contact with mineral oils, water and other fluids
  • Lined tanks should NOT be used for storage
  • Ambient temperatures and atmospheric pressures normally encountered within buildings are acceptable. Avoid entering areas where mists or vapours have built up as a result of abnormal temperatures or pressures without the proper breathing equipment and protective clothing
