Ritchie 17963 Stainless Steel Retaining Ring

The Ritchie Retaining Ring (#17963) is a stainless steel replacement part designed for use in Ritchie EcoFount units and the discontinued Commander series waterers. This retaining ring works together with the drinkwell (part #18447) to securely hold the drinkwell in place, ensuring proper positioning and reliable operation of your waterer.

Built for durability and long-term use, this retaining ring helps maintain a tight, secure fit to prevent movement or wear over time—keeping your waterer functioning as intended.

What this part is. The 17963 is the stainless steel retaining ring. Ritchie publishes no description of its own for this one, so we are not going to invent specifications it does not state.

Two sizes of Ritchie seal foam, and they are not interchangeable. 14866 is a 1/2 in. x 3/4 in. foam on a 10 foot roll; 16523 is a 1/4 in. x 3/4 in. foam on a 25 foot roll. Measure the gap you are sealing before you choose.

The unit breakdowns linked below are ours, and each waterer listed there is one we have recorded as calling for the 17963.
