Easily and effectively apply primer and solvent cement on larger pipes with the Weld-On 14108 SuperSwab 4" Applicator. This versatile swab applicator features a disposable swab tip and a reusable plastic handle cap that fits both quart and gallon containers. The disposable swab tips can be positioned in two places on the handle, allowing them to reach shallower or deeper into different sized primer and cement cans. The ridged plastic handle offers a secure grip while the swab tip delivers smooth application of cement and primer onto 4- to 8-inch-diameter piping in the quart position and from 6- to 24-inch diameter piping in the gallon position.
