Doing a little plumbing at the house recently, and we have a clawfoot tub with water lines coming out of the tub deck. It was some all-in-one tub and faucet combo we got from Lowe's over 10 years ago. The faucet side has male connectors, and the water pipe is female. I needed to replace it, and my wife ordered the faucet from Amazon. Problem is, the new faucet has a female connection instead of male. Basically to make it work without redoing the water lines, I need a super short 3/4 inch by 3/4 inch pipe nipple. I bought the shortest one at Home Depot, but its still too long. Does anyone make one that is shorter than an inch?

could you even get enough thread engagement with a nipple that short?


I don't know sh*t about plumbing so genuinely curious.

What you have is a close nipple. That's as short as they get.

But both my existing water supply and the new faucet have female. The nipple is the way to go as its double male. I was just curious if anyone made a super short one.

A close nipple is the shortest they make, they are almost exactly 1" long. Normally those type of faucets have a stop or shut off valve in line above the floor.


If you're able to/comfortable taking the old nipple out of the tub deck, measure how much longer it needs to be and go get 2 new nipples cut to length.

Or take the female end off of the nipple going up from the tub deck, add a MIP angle stop and use a water flex connector.

Or add a stop and escutcheon at the floor, grab some tubing benders and some 3/8 chrome supply tube and get to it.



The world is your oyster. 10 plumbers would fix it 10 different ways.

FWIW, the supply gods at McMaster show their shortest 3/4" close nipple as 1-3/8" long.

I also like smaller nipples.
