New improved design, made of molded one-piece plastic, make the new Blue Finisher waterswing better than the stainless waterswing, at a galvanized price. It is non-corrosive, self-cleaning with no internal areas for sludge deposits, and threads molded right in for consistency and better sealing. Wrench flats for easy nipple maintenance and stainless steel grommet won't wear out. Our Patented Exclusive "Play Guard" will reduce water waste during the act of drinking. It forces the pigs to come at the nipple Head-On, eliminating nipple side biting & the resulting waste of water that goes directly into your pit.
