Heavy-Duty Leak Detection Fluid™, Concentrate 55 Gallon Drum (4:1 dilution) Pressure testing leaks even at very low flowsHD LDF RTU works in freezing conditions at a 4: 1 Ratio. Heavy Duty Leak Detection Fluid Concentrate (HD LDF C) diluted to a 4: 1 ratio, outperforms competitive products in temperatures as low as 15 Celsius (5 Fahrenheit). Since much leak detection work is conducted outdoors, or in refrigerated areas, performance can be impacted if exposure to extremely cold or freezing temperatures prevents the applied leak detection fluid from forming bubbles in
