Do I need a new spray pal?

[Yogurt]

We just moved and tried to take our spray pal with us. My old house was a beach house and my husband said part of the spray pal was like stuck on the toilet because the toilet is all old and cruddy and coroded. I only have the hose and the sprayer, not the splitter piece.

I am going to come back with a picture of the part I need. My husband has bought 2 different splitter type things at hardware stores, and neither has been right or fit. Can i buy this piece separately from spray pal? I can't seem to find it sold online. I hate to buy a whole new spray pal just for this part.
Thanks

I think at least one person here has made their own spray with supplies from the hardware store... maybe they'll come in and have some insight to offer.

I had a really hard time finding a splitter that fit with my first sprayer (cheap one from china) and ended up just buying a while new sprayer that came with a splitter. if you know the diameter,this might work:

if you're in the market for a new one, i have the Big John bidet sprayer and it works great
