The Fuel Heater Straight Connector is used to facilitate the seamless flow of fuel into the fuel heater, which serves the purpose of maintaining the fuel at an optimal temperature in cold weather conditions or environments. It is made of steel material to withstand the high temperatures and pressure fluctuations encountered during the operation.Attributes:• Hardened to Rockwell C scale hardness of 23 - 30, which determines it's resistant to deformation and wear• Hex shape of the connector provides a better gripping surface for tightening and loosening Applications:The Fuel Heater Straight Connector provides a secure and leak-free connection for effectively flowing fuel for efficient combustion and smooth engine operation.
