My home air conditioning leakage fluorine, repair air conditioning Master said, because the three-way valve cap is not there (valve that there is oil), is that so? Thank you
No, there is also an inner six angle screw in the three-way valve to adjust the opening and closing.
The valves used on domestic machines are of general quality, which are not comparable to those used in industrial or commercial parts, so they are not only to be tightened, but also sealed externally.
If the cap doesn't screw tightly, it will leak cold medium.Because there have been signs of oil stains.
