The 'nipple' is molded into the body of the fixture. Dawg..Don't know how to determine the plastic type if the customer service people don't know. I hadn't thought of tapping in a thread for a real nipple. Will take a closer look at that possiblity. Size may be a problem unless I could build the original up then tap it.
Will epoxy adhere to ABS if that is what is?
Thanks to all.
