It’s easy to add some automation to your poultry drinking system with these horizontal sipper nipples. Eliminate the need to fill waterers daily, put an end to leaking, rusted-out metal waterers and help keep your coop and run drier for a healthier flock. This 5-pack of horizontal twist-in nipples can be used in a low-pressure pipe system or inserted into a 3/8-inch drilled hole in the side of a pail or 55-gallon drum. Drill bit not included.
