12.2.2. R410A Tools

1. Copper tube gauge for clearance adjustment
(used when flaring with the conventional flaring tool (clutch
type))
This gauge makes it easy to set the clearance for the
copper tube to 1.0-1.5 mm from the clamp bar of the
flaring tool.
2. Flaring tool (clutch type)
In the R410A flaring tool, the receiving hole for the
clamp bar is enlarged so the clearance from the clamp
bar can be set to 0-0.5 mm, and the spring inside the
tool is strengthened to increase the strength of the pipe-
expanding torque. This flaring tools can also be used
with R22 piping, so we recommend that you select it if
you are buying a new flaring tool.
3. Torque wrenches
For 1/4 (opposite side x torque)
For 3/8 (opposite side x torque)
For 1/2 (opposite side x torque)
4. Manifold gauge
Because the pressure is higher for the R410A type, the conventional type cannot be used.
High-pressure gauge (red)
Low-pressure gauge (blue)
The shape of the manifold ports has been changed to prevent the possibility of mistakenly charging with another type of
refrigerant.
