I've never bought anything online after what has happened to friends of mine.. All of them get ripped off so I'm staying away from that
I got my nipples from this place as many on the board have.
http://www.qcsupply.com/farm-livest...aterers/420006-poly-threaded-body-nipple.html You could order over the phone or ask for a catalog if you don't want to order online but maybe you would want to let yourself experiment with a small online order from an established company. 4 nipples with shipping to me was $7.71 so not much risk. I have no connection with them other than this. From their site........
From its humble beginnings in a garage, selling livestock products to local producers in 1982, QC Supply has grown into an International distributor to farms, businesses and resellers worldwide.
QC offers thousands of brand names, as well as hard-to-find products. QC has its own, patented line of clothing (Five Rock), fans (Durafan) and heaters (Scorpion). Customers return to QC for in-house technical support experts trained in a wide variety of products. These experts are able to answer technical questions, aid customers in product selection and support after the sale. This level of customer assistance is a primary differentiator from competitors.
Headquartered in Schuyler, NE, QC Supply is comprised of a call center, retail store and the largest of 3 warehouses. Other warehouses are located in Missouri and Oklahoma. The recent acquisition of Gillis Ag resulted in distribution sites in Iowa and Minnesota. A second retail store is located in Elkhorn, NE. All of these locations give QC a closer presence and an ability to more quickly serve customers.
