TOTO THU9090R adapter for extending the supply line farther lower to help with the Washlet installation on a TOTO Aquia.

This converts the 7/8" female to 7/8" male threads as an extension.

Got the Toto C200 washlet for my wife = happy wife, happy life, as they say..:D

Problem: the Tee-fitting supplied with the C200 [IMG_1691] has a bottom flange that is 7/8" IPS - so far so good - but this flange has a 1/8" thickness that is machined flat on the mating surface [IMG_1690]. This flat surface doesn't make a water-tight seal using the typical USA 7/8" & cone washer connection that toilet supply hoses here in the US come with.

What water supply hose connection type and/or washer do I need to connect to my angle stop? Will the Toto THU9090R hose extension's white plastic connector fit this flange? I'd prefer a hose that has a 3/8" compression fitting at the angle stop.

Thanks in advance!

Check the toilet supply lines at your favorite plumbing stuff place. Most of them, I think, have a flat washer rather than a cone.

You can use a little silicone grease on the washer. No tape.

Most have 3/8 compression on the other end -- just what you want.

Thanks will make a run at it with a proper plumbing supply shop. All Home Despot's 7/8" fittings had a small brass cone in the base, which made the connection not sealable with the Toto flat-faced Tee fitting and its flat washer. Stay tuned.

The tee comes with an extra washer for the fill valve. Use one on the top of the fitting, and save the second one. The flex connector has a washer already on it's end.

And the new one.
