This \u003cstrong\u003eexternal seat drain valve\u003c\/strong\u003e distributed by FleetPro Parts \u0026amp; Tires threads into a \u003cstrong\u003e1\/4 in NPT\u003c\/strong\u003e port on an air reservoir and gives you a clean, one-hand way to purge the moisture that the compressor pushes into the tanks every working day. Let that water sit and it goes where the air goes — into the valves, into the lines, and in January into a slug of ice that stops the system cold. A drain valve that will not seal, or one whose stem has seized, quietly ends the daily habit that keeps all of it out. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003ePurge It Daily: The External Seat Drain Valve Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eexternal seat\u003c\/strong\u003e is the detail worth paying attention to. With the sealing seat on the outside of the tank boss, the valve closes against a surface you can see and reach, instead of depending on a seat buried in the reservoir where the sludge collects. Combined with a standard \u003cstrong\u003e1\/4 in NPT\u003c\/strong\u003e thread, that makes this a straightforward swap on the reservoirs and tanks already on the truck.\u003c\/p\u003e\n\n\u003cp\u003eFit one on each tank and drain them at the end of the day while the system is still warm and the water has not settled into the low corners. At FleetPro Parts \u0026amp; Tires we treat the drain valve as maintenance hardware, not an afterthought, because the alternative shows up later as a rusted tank or a frozen brake circuit.
