EXCLUSIVE to Cobco, these Poppet System Drains feature 1" male NPT pivot and wheel roll drain, with a 1 1/2 # stainless steel spring. System drains close at 1 1/2# of pressure and open at 3 # of pressure, so it works well in L.E.P.A. pivots that require low operating pressure. A poppet system drain fits inside your pipeline and is not subject to the problems of rubber drains. Replace existing leaky metal drains and/or order as new equipment option in "Valley" pivots and "Wade Rain" wheel rolls.
