Chesterton’s 389 Synthetic Tapping Compound is a thick, non drip, high performance, synthetic metal working fluid. It provides the industrial performance of conventional petroleum and solvent based fluids while eliminating the hazards normally associated with these traditional products. Higher temperature and shear stable lubricants allow 389 to continue to lubricate under conditions that will cause petroleum oils to break down and start to smoke. The superior lubrication,combined with maximum heat dissipating capability results in a product which extends tool life and keeps taps cool to permit rapid cutting.

Chesterton’s 389 is effective for all hand and automatic tapping operations and is used for a variety of demanding metal cutting operations over a broad range of metals, including aluminum. Since there is no chlorine or sulfur in the product, the working of stainless steel is facilitated without fear of embrittlement.

389 Synthetic Tapping Compound does not smoke, mist or fume during use. The result is a cleaner, safer work environment. A near neutral pH minimizes the potential for skin irritation and defatting commonly caused by organic solvent based cutting fluids.
