Reed Tapping Compound is food-grade and does not contaminate water, making it environmentally friendly. It is offered as thick compound in a 16 ounce can or as a thinner, modified grease in an 8 ounce squeezeable bottle. Tapping Compound requires direct hand application by the user. Tapping Grease has better flow characteristics which allows the operator to squirt tapping grease on the tool and to NOT get it on his hands.
