These seem to be very common for a Y with a shutoff valve. Problem is I'm trying to attach it to 3/4 inch flexible tubing from a pump, thus the type of connector really doesn't fit in this form. I'd have to do some creative modification and I can't really visualize how to make this type of thing connect to tubing. The pic that I posted in my earlier post above would fit the tubing perfect, I just can't find ANYTHING like it with a shut off valve.
