Air Tank Drain Cock

5 Pack

Velvac®

An air tank drain cock, also known as a petcock, is a small valve located on the bottom of an air tank in a truck's compressed air system. Its primary function is to release any accumulated moisture or debris from the tank that may have collected during normal operation. The valve can be manually opened to allow for drainage, and then closed once the draining process is complete. This helps maintain proper air pressure and prevents corrosion or damage to other components in the system. The Air Tank Drain Cock part number 036019 is specifically designed for use in trucks and other heavy-duty vehicles.
