The original Lixit nipple waterer is trusted for pigs, sheep, goats, and other farm animals, and is equally effective in dog kennels. Durable enough for pigs from farrow to finish. This Valve is compatible with standard ½"-14 NPT fittings and can be installed either horizontally or at an angle. Please note: it is not intended for use with standard faucets. The only nipple waterer designed with an extruded hollow center, this pig waterer nipple directs water naturally through the middle for efficient, straight-to-mouth flow. Made of high-quality stainless steel. Flow can be adjusted between 20 and 60+ PSI.
