Caution

There is no problem of such as corrosion as unevenness of color on the surface of nut was caused by the quench at baking finish for the surface of inside screw.
We adopt "Installation Seminar System" and "Project Registration System" for FIRELESS JOINT to prevent such a refrigerant leakage trouble caused by a mistake at installation work. Please ask INABA for details.
Quench at baking finish for the surface of insdie screw is not applied for FJ-635.
