Raypak 105B Cast Iron Inlet/Outlet Header (006887F)

Raypak 105B Cast Iron Inlet/Outlet Header is a heater water-connection component that helps route water into or out of the heat exchanger assembly. 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 006887F, physical shape, connection points, and any model-specific notes against the component already installed on the heater or plumbing assembly.

Headers and flange kits must match the heater model, material, port configuration, and associated gasket or hardware requirements to avoid leaks and fitment problems. 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.

• Supports inlet or outlet water flow on the listed heater model
• Designed for the matching Raypak header or flange application
• Useful when repairing cracked, corroded, or leaking water-side components
• Confirm cast iron, bronze, or Capron style where applicable
• Inspect gaskets, bolts, and mating surfaces during replacement
