Rated 2 out of 5 by from Delta RP51505 55/64" Female to Male Aerator Adapto Part works but is made of plastic, not metal as hoped. No where in the product description does it mention what the connector is made from and $7 is high for what you get. Don't be mislead.

Rated 1 out of 5 by from Just wrong Despite what Delta will tell you on their web site, this part will NOT work in the Talbott or Bellini series faucets. Both sides of it are too small. In fact, if you propose to attach anything to these faucets, you will have to go to a machine shop and have a custom fitting created. This is apparently a conscious decision on Delta's part.

Will this fit a Model 19922?

Asked by: J D
Hi, JD! Thank you for your question. The Delta RP51505 does fit the sprayer assembly on the 19922-SSSD-DST. However, we do not recommend to connect anything to pull-out or pull-down kitchen faucets, as potential pressure fluctuations during operation may result in the hose rupturing. Best Regards, Rosanna

Does this fit the 21902LF faucet

Asked by: brad
Thank you for your question, Brad. If the code on the back of the faucet base is "413763" you can use this adapter to convert the spout to 55/64"-27 male threads. If the code on the back is "449401", the faucet does not have an adapter. Best regards, Jon

does this adaptor fit a rp53998 aerator with a 55/64 thread on the other end.

Asked by: charlie
Hi Charlie, Thank you for your question. This adapter converts 21.5X 1-6 g metric thread to 55/64”-27 standard thread. Unfortunately, if the spout uses an RP53998 aerator, the threads are M24-1 and will not accept this adapter. Best regards, Jon

Is this the adapter that is needed to attach the (Ultimate) PUR Water Filter

Asked by: D
Hi D, Thank you for your question. The RP51505 adapter works only on faucets with a female metric 21.5X 1-6 g threaded spout. Please also verify that the filter will connect to male 55/64”-27 threads. Best regards, Jon

WILL THIS FIT 4297-DST?

Asked by: CHARLIE
Hi Charlie, Thank you for your question! The RP51505 (works only on those faucets with female metric 21.5X 1-6 g thread or 55/64”-27 thread) adapter will not work on the model 4297-DST. The 4297-DST aerator has a thread size of 13/16"-27 Male. Best regards, Brandis

Asked by: Tim
Hello Tim, Thank you for your question. Unfortunately, RP51505 is the only adaptor we make. You will need to look for a third party part to match what you need. I hope this helps. Best Regards, Justin

Does this adaptor work with 11946-SSSD-DST?

I have purchased the 11946-SSSD-DST model which has a small cache aerator, I believe it is RP70718. I would like to mount a swivel aerator to this faucet but am having a hard time finding an adaptor. If this doesn't fit, do you have one that does?
Asked by: Bryan
Hello Bryan, Thank you for your question! Yes, The RP51505 should work with the RP70718. I hope this helps!
