Making it much easier and faster to connect barbed fittings to 1/2 in. drip irrigation tubing, this handy tool holds the fittings firmly in place and gives you better leverage for a leak-tight connection. The ergonomic tool is made of heavy gauge plastic and can be used with all Rain Bird 1/2 in. couplings, elbows and tees. It makes fast work of even the largest drip system installations.
