Part number 007400F is one of the most frequently replaced Raypak HSI parts and is typically in stock at Memphis Control Center.

Use the model number and serial number from the rating plate on your Raypak unit. With those numbers you can find the correct parts list in the equipment installation manual or contact our team and we'll help identify the right replacement part for your specific model.

Are these genuine OEM Raypak parts or aftermarket?

The parts we carry are OEM-quality replacement parts designed to Raypak specifications for exact fit and function. Using the correct OEM-specified part ensures proper performance as designed by the manufacturer.
