What thread size is your standard Gallon soap container? Need to get a push spout..

[NewShockerGuy]

I am starting to get the 1 gallon jugs of product for my personal use. Which look like these:



I am on usplastic's website and saw the following:

Dispensing Pumps | U.S. Plastic Corp.

They have thread size from:
38/400
28/400
24/410

Just wondering what the standard is? I have 3 jugs of soap and it gets a little tiresome pouring them out into a little container and spilling the ratios... I feel like this would be a good solution.

Thanks,
-Nigel

38/400 is the thread size you will need for your soaps
