55/64 male aerator to 1/2 male IPS?

[elbon00]

Hi, I am trying to connect a Brita filter to the kitchen sink in my RV. The Brita came with a couple of adapters, none of which work. Local plumbing supply shop says I need the sizes noted in the subject line. The aerator threads are narrow, while the faucet side has wider threads. The guy at the shop did test / confirm the faucet side is 1/2 IPS, but said it could also be referred to as NPT or MIP. I've searched high and low and cannot find such an adapter. I might be willing to do it with 2 pieces if necessary. The attached picture shows the faucet head on the left (1/2 IPS) and the Brita with one of the adapters on the right.

Would really appreciate any help.

Thanks,
Jeff

better to go undersink with a different filter.
but if you insist: start with https://www.amazon.com/Faucet-Adapter-Aerater-Adapter-B/dp/B08HCNNM4N/ref=sr_1_1?crid=2DFG2JHSBDL04&dib=eyJ2IjoiMSJ9.ZVHlx4dLwUjTykeCdmq1RfNGl6WQHuB3bEiLkoX3yKiuojItXAk2q6IscQTllszaD7XgfaOMmhfzi05cUv9B6ATg3rQh6YHVwONCEuIgZguctesaO3httMbQjWr8cowHu05WPRcx7CVFDjCjX-52w36zWjo9KGBL5Er8OpMD2i8j6gGjKF9klYVgoY2g4vDWKF7hKPWtoUoP0ArYlrFMhZcUz5yU6FbYlh63H03y0BLD0y00YAOJ27aOBTV9hOYHPMFy2uwXbsx-5q_2wqlVBsclYrfUtACmpWVp_R6yWVU.9XmUJ5FMrL12aFHmWf-Vx65ngGy8w-gtn1oGAX5dCXQ&dib_tag=se&keywords=55/64+female+to+garden+hose&qid=1718739256&sprefix=55/64,aps,149&sr=8-1
then adapt garden hose threads to 1/2" fip

Breplum - thank you for taking time to respond. I may just replace the faucet with one that has a standard aerator thread, but will consider the options you mention.

You are holding a pull-out faucet sprayer which has 1/2 NPT threads on the inlet. Inside the center of the spray head (discharge end) will be an aerator that may or may not be removable. Some are referred to as a cache style and you use a special wrench socket to remove. With the aerator pulled out the threads will be finer machine threads like what you see on the Brita adapter. The most common sizes are 57/64" and 15/16". In many cases, the cache female socket will not allow an adapter to be installed. In any case, the adapter would go into the center of the spray head and not on the 1/2" NPT end.
