Edstrom's Piglet Nipple is designed for use by baby pigs through 50 pounds. Nipple body is solid 303-Stainless Steel. Calibrated to discharge 1.5 pints per minute at 40 psi. 5 year warranty by manufacturer.
How it Works: To drink, the pig simply moves the stem by biting on it, releasing water. When the pig releases the end of the stem, the elasticity of the silicone rubber diaphragm located behind the stem head pushes the head back to the closed position, stopping the flow of water.
