This is a BRAND NEW OEM Aprilaire Humidifier Yellow Water Orifice. This simple but critical part regulates the flow of water into the humidifier. Over time it can become clogged with sediments or mineral deposits. It should be replaced annually for optimum performance. Be sure to clean or replace your In Line Strainer (Aprilaire part # AP-4231) when you replace the orifice.
