The Trojan line of watering cups is great for both small and larger animals. The cups feature a smooth, powder coated finish with no sharp or welded corners for a safe drinking option that is also easy to clean. These Trojan watering cups feature our Trojan 393 Pressure Valve and a brass adapter with a ¾” MPT connection. All of our cups have the same bolt pattern and spacing of 3 ¼” center-to-center.
