Technical Datasheet Vena® TECHNOSIL SAE J20R3 Class A Applications It is especially recommended for use in water and ethylene glycol-based engine coolant system applications. For the automotive industry, the most common standard for coolant system hoses is SAE J20, which classifies them according to type of service. This reference, SAE 20R3, are for heater service. This type of hose is used in connecting heater systems and other components in the coolant circulating systems of ground vehicles (for example in heavy duty truck and bus engines). Limitations Respect the work pressure established values. Gas oil and oil stains do not damage the tubes, but they should not be used to transport fuel or oil, nor be submerged in these liquids. Smooth inner and outer appearance, and blue color. Excellent resistance to thermal aging and oxidizing agents (oxygen, ozone, UV). Operational temperature range from -60°C (-75 F) to +180°C (356 F). The standard manufacturing length is 76 meters long (249.34 ft.), although it is available in shorter lengths if necessary. This product is not recommended for the transport of abrasive particles.
