The Raypak 006707F Return Header is an OEM replacement part engineered for RP2100-series pool & spa heaters—including models 206A, 266A, 336A, 406A and their Low-NOx/Versa II / Millivolt variants. Crafted from durable polymer (Capron) with a gasket, this header assembly seals the return side of the heat exchanger, preventing leaks and securing proper flow. When the return header becomes cracked, warped, or its sealing surfaces compromised, heater efficiency and safety can suffer. Replacing it restores factory-tight sealing, correct sensor alignment, and reliable heater operation under load.
