Our drum siphon adapters are for use with horizontal draining of 30 and 55 gallon drums. They reduce residual liquids left in drums, and are a chemical resistant, solid cast brass. Great option to help avoid environmental cost associated with removal and disposal of up to 2-3 gallons of liquid left in drum by reducing liquid to just a few ounces.These are ideal for use with expensive non-corrosive or non-visors liquids. The siphon screws into 3/4" NPT bung opening, and the opposite end accepts a 3/4" NPT male faucet threat. The adjustable collar compensates for bungs in varying positions and eliminates need for dangerous drum tipping or rolling. Available as a package or just the adapter alone.
