Poppet Drain Cock

An item designed to drain fluids from fuel systems, tanks, filters, or similar items. It has a mounting end, a free flowing end, and a quick-acting nonmetallic sealed closure, usually spring loaded, that holds it in an "off" position. It requires no lubrication other than from the fluid being drained.
