The Raypak 105A Bronze Return Header is a replacement return header for select Raypak heater models. Headers route water through the heat exchanger and provide the connection point between the heater body, tube bundle, and plumbing system. Part 004902F is a practical repair choice when the existing header is cracked, leaking, rusted, freeze damaged, or has worn sealing surfaces that can no longer hold properly.This bronze header should be matched to the exact heater model, exchanger configuration, and header position before installation. Since header failures may be related to freeze exposure, water chemistry, gasket wear, or flow problems, it is a good idea to inspect the surrounding gaskets, bolts, bypass components, and tube bundle at the same time. Correct alignment and even fastening are important to prevent leaks and avoid stress on the exchanger.
