Thank you for your question, Eddie. The RP53998 aerator has a thread size of M21.5x1-6G. The RP51505 adapter will convert this size to a male 55/64”-27 thread. Unfortunately, we do not make an adapter for the M24x1 size, but you may be able to find a compatible one locally or online.
Best regards, Jon
