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).
