Standoffs raise the pump level to compensate for drums with a high lip, allowing small containers to be placed beneath the tap. Pump standoffs are available in 4-inch heights to fit plastic containers, and in 4-inch heights for galvanized steel drums. The new 12-inch standoff allows you to place the receiving container on the drum for easier transfer. We offer stainless steel standoffs as an additional accessory if desired. All of these fittings are National Pipe Tapered and seal with PTFE Tap. Alternatively, use a lock-nut with appropriate o-ring. See lock-nut instructions.
