R410A tools
Can R22 tools be used?
Gas leak detector
R410A has high pressures beyond the measurement range of existing
gauges.
Hose material have been changed to improve the pressure resistance.
Dedicated for HFC refrigerant.
1/4in. and 3/8in.
Description
Clamp bar hole has been enlarged to reinforce the spring strength in the tool.
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
vacuum pumps.
It is difficult to measure R410A with a charging cylinder because the
refrigerant bubbles due to high pressure and high-speed vaporization
