The 43060-HD introduces dense, non-toxic smoke into the system under controlled pressure. The smoke escapes at leak points, making even the smallest leaks immediately visible. This eliminates guesswork and dramatically reduces diagnostic time compared to traditional methods.Available Accessories 43060-DW-LG: Diffuser Assembly – Long 43060-HDBR-9: 9" Bladder Ring 43060-HDLB-9: Large Bladder for Heavy-Duty Truck 43060-OL: 8 oz Bottle of Smoke Producing Fluid (replacement) Why Choose the Mastercool 43060-HD?
