Reptile Basics VE-6 Rack Water Dish Questions

I have 2 reptile basic ve-6 racks. The tubs are 4 1/4" high and ~7 and ~14" wide (two different tubs). Will the 4" coupling\16oz deli cup combo work in these? I am currently using $0.50 food containers from wal-mart that fit great and are much bigger than the couplings would be, but they constantly tip them over. I feel like a 4" coupling would be too tall for these tubs and the snakes wouldn't be able to drink out of them.... Can anyone confirm\deny? I would really like to stop drying out tubs\beddings.

No it will not you want to use 12 oz deli with coupling no higher than 2 to 2.5 inches

I use this https://www.homedepot.com/p/NDS-4-in...4P06/100172701 (2 inches heigh) or cut a pipe to the same hight with tubs that low.

12oz Deli cups fit in that securely? And where do you get your deli cups, or more importantly, what is the Top diameter? There are so many different types of deli cups lol

Yes they fit securely.

To use as water dish I get my deli cups from here https://www.webstaurantstore.com/cho...7DM12BULK.html , they do not do the white ones anymore but still do the clear ones.

The pipe fitting is 4 inches
