Adaptation:Fit for R-454B R-32 Tanks
Size: 1/4 inch female × 1/4 inch male, suitable for standard HVAC interface
Material:The product is made of high-quality brass and has precision threads, which are resistant to high pressure and corrosion, have a long service life, and good sealing.
Installation direction:The reverse thread needs to be tightened counterclockwise (conventional threads are clockwise). The interface rotation direction must be confirmed during installation and cannot be forced.
Professional operation:It is recommended to be used by certified HVAC technicians. Before use, check whether the interface has oil or impurities, and ensure that the sealing surface is clean.
Compatibility warning:It is strictly forbidden to use it in other refrigerant systems such as R22, R410A, or force connection with the positive thread interface.
Working pressure:Maximum tolerance pressure≥500psi (about 3.45MPa)
Sealing method:Metal cone seal (no additional gasket required).
Pressure test:Air tightness test can be performed before first use.
Storage and maintenance:When not in use for a long time, it needs to be covered with a dust cap and stored in a dry environment to prevent oxidation of the brass surface from affecting the sealing performance.
