Peach Teats® are designed to function like a real cow's teat, moving all the time while calf is suckling. Unique, patented internal collapsing flap-valve holds milk in teat instead of going back into container, making it much more responsive to calf's needs. Milk opening slits on each side of nipple (instead of crown) help prevent leaking, even when used at the bottom of a milk container. Nipple is manufactured from natural rubber, ensuring teat is more acceptable and comfortable to calf; helps eliminate mouth ulcers. Black Teat is manufactured from a rubber/carbon mixture for extra UV protection to help reduce fading and deterioration in harsh sunlight. Valve is made from micro-thin, extremely durable urethane for long-lasting performance. Valve never closes in its relaxed state – cannot be blocked; makes teat self-cleaning. Teats can be pulled through or screwed on. Can be used for tube or gravity feeding using any container. Hole size: 7/8". Replacement Teats and Caps sold separately.
