Parker Hannifin’s Parflex electrically heated selective catalytic reduction (SCR) hose assemblies were designed for heating and conveying diesel exhaust fluid throughout the SCR system on commercial vehicles. Parker says the hoses feature a profile that improves time and thaw consistency performance over traditional coolant heated hoses. Parflex SCR hose locks in electrical heating wires with an extruded cover, providing protection to the entire hose. Standard fittings outfit heating throughout the entire assembly, while an over-mold protects all electrical connections from water/dust ingression. The SCR suction/throttle line offers a thermoplastic core and jacket, while the pressure line hose features a formulated polyamide core tube for higher temperature applications. Both hoses are available in a 6-mm (0.2-in) size; assemblies have various options for fittings, electrical connectors, and overall lengths for customization and are offered for 12- or 24-V systems.
