Know before you buy
Yes, Double Protect Ultra is specifically formulated to protect mixed-metal loops, including those containing copper, nickel, brass, and aluminum, against corrosion.
No, this is a ready-mixed solution. You can pour it directly into your cooling loop straight from the bottle without any additional preparation.
While the manufacturer recommends an annual exchange for optimal system health, the fluid is stable enough to be replaced every 24 months under normal operating conditions.
The fluid is designed with extremely low electrical conductivity to minimize the risk of short circuits. However, you should always power down your system and clean up any spills immediately if a leak occurs.
No, this is a clear, odorless fluid. It does not contain dyes, which helps prevent staining or residue buildup in your tubing and water blocks over time.
