“We’ve cut down on waste. We have none, Before the change, we failed to capture between 10-15% of the sealant.” Notes Al Perry, Quality-Control Manager for A.O. Smith.”

A.O. Smith Water Products Co., of McBee, SC uses Loctite Corporation’s standard Marco II sealant dispensing equipment with a heavy-duty foot pedal to seal fittings for its line of water heaters. Operators dispensed the sealant from one-liter bottles into the Marco II system. Typically, these systems come equipped with a dispense tip on the end, allowing the operator to apply the sealant through the needle to the part. Loctite also adds a square plastic blockto improve the efficiency of the system.
