Couldn’t find this anywhere else!

In case this helps anyone-- I bought a Brondell bidet attachment and the T-valve and washer couldn't reach the threads on the line coming out of my toilet tank no matter what I did. I actually wasn't sure what this adapter was based on the description, but it looked like something that could help make the connection so I bought it. Worked like a charm! I'm so happy.

It was the piece we needed. Accurate description, arrived as promised.

Perfect fit to enable access to the bidet valve beneath our Koehler toilet.
