CABLE OPERATED AIR TANK DRAIN VALVE.
THIS IS A UNIVERSAL VALVE THAT FEATURES 1/4" NPT THREAD AND 5 FOOT OF CABLE. 

1/4" NPT IS THE STANDARD FOR MOST AIR TANKS, AND THIS UNIT WILL FIT MILITARY APPLICATIONS IN THE 2.5 TON AND 5 TON CLASS OF VEHICLES.

CABLE OPERATION MEANS YOU DON'T HAVE TO CLIMB UNDER YOUR TRUCK TO DRAIN THE TANKS ANYMORE, WHICH MAY BE A HARD TASK FOR THOSE OF US WITH DISABILITIES OR BACK PROBLEMS. I'M JUST TOO DAMN OLD TO CLIMB UNDER MY TRUCK, SO THIS IS AN AWESOME ADDITION THAT MAKES MY LIFE A LOT EASIER.
I ALSO OFFER THESE IN SETS OF TWO AT A REDUCED PRICE!!!

INSTALLATION REQUIRES NO EXTRA FITTINGS, JUST SCREW THESE INTO THE BOTTOM OF THE TANK AND PULL THE WIRE TO OPERATE. THESE ARE DESIGNED TO BE PULLED SIDEWAYS TO OPERATE, NOT STRAIGHT FORWARD LIKE OTHER STYLES OF VALVE.
