Raypak 337A Refractory Retainer Kit is a Raypak heater refractory retainer kit used to help secure and support refractory material within the combustion area. Refractory pieces protect nearby heater surfaces from burner heat, so the retaining hardware needs to fit correctly and hold the material in the intended position. This kit is intended for the specific model family listed in the product title and should be matched by part number 010264F before repair work begins. It is a practical replacement when the original retainer is rusted, distorted, missing, or removed during a broader burner tray, heat exchanger, or combustion chamber service. Designed for the Raypak model family shown in the product title. Helps hold refractory material securely in the combustion chamber area. Recommended when the existing retainer is corroded, damaged, or incomplete. Check the heater model and part number 010264F for proper fit. Best installed during service by a qualified pool heater professional.
