Frequently asked questions
Does the listing give the mounting pattern for a CPU?
No. The listing describes the applications and dimensions but not the mounting pattern. Check the mounting holes and port size against your CPU or system before fitting.
Why does the leak rate matter?
A low leak rate of less than 5×10⁻⁶ mbar·l/s indicates a well-sealed brazed body. Even so, pressure-test the full loop after assembly to confirm there are no leaks at the fittings.
