Pro-Tek HTF

Hydrostatic & Pressure Vessel Testing Fluids

Hydrostatic testing fluids are used to assure the integrity of pipes, valves, and other parts that need hold pressures accurately with no leaks or structural integrity.  The pressure vessel testing fluid used in these tests needs to assure that no rust or corrosion is left when the fluid is removed while at the same time leaving a microscopic or unnoticeable layer of chemical.
