Raypak R185A/R185B Retainer Kit is a heater internal service component used to keep combustion heat, airflow, or insulation materials positioned correctly inside compatible Raypak equipment. This item is intended for targeted repair work where matching the original part number and equipment series matters more than using a generic substitute. For best results, compare the part number 006744F, physical shape, connection points, and any model-specific notes against the component already installed on the heater or plumbing assembly.These parts are often small but important to safe and efficient heater operation, especially during a rebuild or when replacing damaged firebox or exchanger-area components. During service, inspect nearby gaskets, fasteners, wiring, seals, brackets, or mating surfaces so the repair does not leave another worn component in place. This is especially important on older Raypak heaters, where heat, water chemistry, vibration, and corrosion can affect multiple parts around the same assembly. Made for the Raypak model or series listed Helps maintain proper internal positioning during heater operation Useful during firebox, refractory, baffle, or retainer repairs Verify the old part number and heater model before installation Replace worn adjacent seals or hardware as needed during service
