TOTO WASHLET T-Connector - THU6234

We have two legacy Toto S300 washlets. Both have been moved a few times and have always been a major pain reassembling. First off, the metal nut is a pain to thread. Second, it tends to strip the float valve. Third, it's super temperamental with how much you tighten (a slight twist can cause or prevent leaking). Recently, one started leaking suddenly. Turns out the gasket in part Thu661 rotted away. After failing to find a similar one at the local Home Depot and becoming majorly frustrated my father recommended this item. I read the reviews, ordered next day delivery, and when it came it took about 5-10 minutes to get them installed and there were zero issues and no leaks. Bravo for recognizing the issue and building a better solution, Toto. Expensive plastic but well worth it.

I recently had my TOTO S350e washlet overhauled/fixed by TOTO. When it came back I replaced the old original adaptor with this new design. The old design was difficult to thread onto the toilet and was prone to cross-threading. This was much easier to install. And I could turn the washlet connection underneath the tank and this got that connection out of view for a cleaner install. A bit expensive but works well and this new design is now standard on their new products. Just make sure it will fit your washlet.

I was a little skeptical at first due to its all-plastic construction, but I was pleasantly surprised. The design is far superior to the old one and it won't reveal its advantages until you need to replace your tank valve and are forced to remove the old valve. That's when you will discover the old style has corroded to the extent that you will not be able to reuse 100%. I wrestled with the old one for 20 mins and at best was able to install it in such a way to have a small drip (3-7) drops a day. That bought me time to order and ship the new style. I removed the old one and WITHOUT tools, was able to install this new style in less than 2 mins. The major design improvement is where it connects to the tank valve. Old style T-valve uses a flat washer that is unforgiving when threading it back to the tank valve. The slightest angle on contact it will leak. The new style uses the familiar tapered donut gasket that will contact and seal regardless of slight angle when tightened. BTW, the application was unclear. I have a Toto s350e washlet and this fits perfectly.

I bought this TOTO THU6234 for my Japanese toilet attachment after the metal one that originally came with the toilet started spraying water everywhere—it was a mess! This replacement did the trick and completely fixed the problem. It was easy to install and fit perfectly. Now, everything works as it should, no more leaks or spraying water all over the place. If you’re having issues with the original part, I definitely recommend this one—it’s a lifesaver!

This was purchased to replace the original one in the picture that came with Toto’s washlet. The original one simply doesn’t fit with the standard toilet fill valve. It’s not only very hard to install (taking hours), but it also straightened the fill valve (causing the risk of water flooding). Toto should feel ashamed for not providing the right component and instead selling it for a high price separately.

This connector works perfectly well to replace the original T-connector of my Toto bidet. It's easy to connect and the most important thing is it doesn't leak. Were it not for the price of this plastic connector, I would have given it a five-star.

This one is a major improvement over the old design. The old design is a guaranteed to be a cross thread leak disaster due to the material differences between it and most toilet’s filler valve inlet. This one is made to match most of these inlets, it screws on and once hand tight, it’s good to go. Only drawback with this design is that the T opening for the inlet tube of the washlet cannot be oriented like the original can so you’ll have to flex the inlet tube with this one. But overall, this newer design is much superior than the old one.

Did the job no leaks.
