Supplied T valve is 7/8" universal size designed to fit directly to your toilet fill valve, not shut off valve.
It is designed to fit regardless of model and made of your toilet.
The only exception supplied T valve would not work is if your existing connection is welded to the fill valve.
If this is the case, measure your shut off valve size and contact us for either 3/8" or 1/2" replacement T valve.
Please feel free to contact us for any question.
