The Midland Haldex 12112 is a screw-type drain cock designed for air brake system drain valve applications. It threads into a 1/4" NPT port, giving technicians a straightforward, tool-friendly way to purge moisture from air tanks and brake components. The screw-type actuation keeps the drain closed under system pressure and opens with a simple turn, reducing the risk of accidental discharge during routine maintenance. Sold as an individual unit by Pro Gear and Transmission. Call us to confirm proper fitment for your specific air system configuration.
