Raypak 207A/D-2 331-407 Air Pressure Switch (008135F)

Raypak 207A/D-2 331-407 Air Pressure Switch is an electrical or control-side service part for compatible Raypak heater operation. 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 008135F, physical shape, connection points, and any model-specific notes against the component already installed on the heater or plumbing assembly.

This type of component is commonly replaced when troubleshooting ignition, temperature sensing, pressure verification, relay function, indicator operation, or control-panel communication. 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.
