What do plumbers and hardware stores call this fitting and its threads?

This question is about a kitchen faucet fitting-I put that info in the required model boxes. I am an amateur homeowner. I can't get the answer I need studying brass fitting displays at Home Depot.

I have a brand new (old) Moen 7310 Legend kitchen faucet. It is installed and works fine, but this model has a side sprayer. My sink does not use a side sprayer. I want to put a plug in the sprayer hole in the faucet body.

Home Depot and Ace Hardware do not have what I need. I do not know the right words to describe the fitting and its thread type to do an online search for a plug to replace it.
It is not pipe thread or pipe thread size and does not seem to be compression fitting.

What is this fitting and its thread pattern called? And any thoughts on obtaining a plug for the hole?

We are only a appliance repair website. I don't know the answer to your question either. You'll need to post that question in a plumbers forum.:)

Here's a good one:

By the way, can you please update your last thread here:
Thanks!

I am aware of the plumbing forum you mentioned. No help there with my specific question.

Are you looking for a plug for that water line? If so, take the hose to a dedicated pumping store (rather than a 'big box' store) and they should be able to provide to you the appropriate fitting to close the pipe off with. They can find the size and threads from the end of the hose.

Thanks for the reply.

I am looking for a plug to go in the faucet body itself.

Prior to installing it, after several trips to home depot, I took the faucet body to Ace Hardware. 1/8 pipe plug and 3/8 fine thread Stainless Steel bolt both started in the opening and then stopped. Guy said to wrap the 3/8 bolt in teflon tape and use that. That leaked. I suspect either the 1/8 pipe plug or the bolt could be forced in, but I am not confident they will seal, and then I am left with a broken faucet. (Note I am an amateur homeowner, not a technician with specialized knowledge, skills and tools.)

I had to have a functioning faucet, so at the moment the faucet is installed and I have a temporary workaround using the fitting end of the hose. I would like to get a plug instead of that because I don't know how good a long term fix that is. (I hurt my back, bruised a rib on a cabinet edge and got an eye full of dried plumbers putty from the work I have already done. Additional removal and reinstall of the faucet body for more comparison trips is not in the cards. In another week or so I will be able to get under the cabinet again enough to remove the hose end and replace it with a plug if I can find one.)

After looking at Home Depot displays for awhile, and making several purchases that did not work,
I see that with brass, there is first something called pipe fittings. There is fip, mip, ips and I don't know what else. The diameters and thread patterns are different than the bolts I am used to in a car or home applications.
There are also things called flare and compression. They are shorter than my fitting and apparently seat via some kind of device on the end rather than the length of the fitting screwed into its receptacle.

What the combination of my hardware store experience, the picture of my hose end above and the picture below suggest to me is that I have need of a brass plug with an American bolt diameter of 3/8" with a fine thread, modified to tapered threading for use in a brass kitchen faucet application.

IF the American hardware industry makes a plug of that type, they would have some sort of words to describe it. It is not flare, compression or pipe thread.
That is what I am trying to get to.

And yet the picture you show is of a hose.




Is it that hose you're just trying to cap off?

I don't understand what you mean by cap off. I need to replace a kitchen faucet sprayer hose with a brass plug.

I need a brass plug that will go in the sprayer hose hole in this brass faucet body. Moen does not show a plug in any of their parts diagrams for this faucet series.

Moen makes two threaded brass parts to go in this outlet. Neither is a plug.

I do not see anything like the plug I need in the Flare, Compression or Pipe fitting displays in the plumbing section of Home Depot. The Ace Hardware clerk (with the faucet body in front of him) performed exactly the same search in his brass fitting stock that I performed at Home Depot.

Before I can look elsewhere for a plug, I need the vocabulary to describe it.

Did that hose screw into the hole in the faucet body that you want to plug?

If so, you had a sample of the diameter and threads that the mating hole uses. I would suggest you take that hose (or its end fitting) to a local dedicated plumbing store (not a big-box retailer) and tell them what you're trying to accomplish. I'm sure they can supply the necessary plug to do it with. It doesn't have to be from Moen, most plumbing fittings use similar threads.

Thank you for the reply. I will keep that in mind for the future. It is not possible for me to do that at this time because of my hurt back and the cut off end of the sprayer hose is temporarily fastened to the faucet so I can use it, see post 5 above.
