I-400-1 — Air/Water Pressure Wash System for Dye Penetrant Testing

Tri-Con Sprayers

Regular price $52.99 Sale

Combine air and water for extra force to tackle high-pressure cleaning, rinsing, and degreasing jobs — or wherever you want to save water. Your airline feeds into the petcock, and then airflow is controlled by a simple turn. Combined air/water pressure will come within 10% of air pressure input. The I-400-1 system connects your ¼-inch air hose directly to the 3/16-inch brass hose barb, which is then secured using a clamp.
