This replacement part supports directional flow control for focused jet output and is best selected by matching the part number, jet family, face diameter, and trim details from the existing spa jet. Because Waterway offers many similar-looking internals across Mini Storm, Poly Storm, Cluster Storm, and Power Storm designs, confirming the exact size and connection details is important before installation.This part is listed under Jets & Parts and should be used as a like-for-like replacement rather than a universal conversion part. Key details from the product listing include: 3-3/8" FD; Threaded; Dir; Smth; Grey.
