Description
The Haldex 12103 manual air tank drain valve lets you drain wet or dry air reservoirs on heavy-duty trucks and trailers without crawling under the tank. It uses a 36 in. closed-loop pull cable so you can operate the valve from a convenient location and fully empty the reservoir of accumulated moisture and oil. The valve threads in with 1/4-18 NPT male connections and comes with Vibra-Seal sealant applied to the threads for a secure fit. This is a genuine Haldex part sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
