New Specification
The incompatible refrigeration oil easily separates from
refrigerant and is in the upper layer inside the suction muffler.
Raising position of the oil back hole enables to back the
refrigeration oil of the upper layer to flow back to the
compressor.

Provided for flaring work (to be used with R22 flare tool).
Provided to prevent the back flow of oil. This adapter enables you to use
New
vacuum pumps.
It is difficult to measure R410A with a charging cylinder because the
New
refrigerant bubbles due to high pressure and high-speed vaporization.
Yes : Substitutable for R410A
Current Specification
Since refrigerant and refrigeration oil are compatible,
refrigeration oil goes back to the compressor through the
lower position oil back hole.
