Description
The Power Products DRC601-4 is a 1/4″ NPT brass drain cock for air tank moisture drainage on heavy-duty commercial vehicles, replacing the Bendix 103385 C-1 style drain valve. The T-handle design provides quick, reliable release of accumulated condensation from air brake reservoirs, helping protect the air system from corrosion. Universal fit on Class 5–8 trucks, tractors, and trailers with 1/4″ NPT air tank drain ports.
Signs You Need a New Air Tank Drain Valve
- Valve leaks air when closed or won’t seal completely
- Handle is seized, corroded, or broken off
- Excessive moisture or oil found in downstream air components
- Visible corrosion or mineral buildup around the valve body
