Tailpiece question

downunder

I'll show my ignorance here but....

The other day I was at a local Tractor Supply store and saw some of their plumbing fittings in a sale bin. These fittings looked somewhat like a reducing bushing on one end and the other end had a flat lip at the very end. Some were pvc, some were copper. The fitting is open all the way through, does not close like a cap plug does. Somewhat like a "T-nut" if you are familiar with that hardware, i.e. round barrel with a flat lip on one end.

The bar code label identified this as a "tailpiece." The only tailpiece that I am aware of is on a sink trap, tub, etc. The store clerk said he did not know what it is used for.

I tried a Google on this but didn't find anything. Just curious.

Did it look like this:



This is the only "tail piece" used in plumbing that I am aware of, and it's a perfect example of a brass or chrome plated brass tail piece. They also come in plastic as well.

The tail piece is part of the drain under a sink. On a kitchen sink it goes between the strainer basket and the P-trap. On a bathroom sink, the tail piece will actually be part of the Pop Out plug assembly that forms the drain, or it will thread into the drain with a fine thread.
