Do these adapters exist??

[Bostondiy]

General Product Question:

I need to install a T Fitting between the water supply from the wall and the line to mu toilet. Unfortunately, the T Fitting that I need to use is designed for a 5/8" line but my current systems is 3/8".

I wanted to know if compression adapters exist to change a water supply from 3/8 to 5/8 and the reverse, from 5/8 back to 3/8. Ideally they would be chrome plated brass but just brass would be fine too. I haven't found them via standard sources.

Do these parts (or a combination of parts) even exist?

Thanks

You have 3/8 coming out of wall?

Yes. Or at least there is a 3/8 coming from the shutoff valve thats attached to the supply coming from the wall.

The valve on the supply from the wall is 3/8. I was hoping to avoid changing that and just find adapters.
