Poultry Water Nipples w/ Gasket & Wing Nut

I do like these & have purchased 7 of their water buckets with these nipples. Plan on replacing one or two fairly frequently & have them on hand. It’s the springs that pop out & you have to replace the whole part. They are well made otherwise. I wish you could buy them in a bulk pack & get a slight discount. They’re a little pricey for one nipple in my opinion, & having so many buckets I need quite a few on hand.
