10.2.2. 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.

Fig. 1 Copper tube gauge for clearance adjustment

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.

For 1/4 (opposite side x torque)	17 mm x 18 N.m (180 kgf.cm)	17 mm x 18 N.m (180 kgf.cm)
For 3/8 (opposite side x torque)	22 mm x 42 N.m (420 kgf.cm)	22 mm x 42 N.m (420 kgf.cm)
For 1/2 (opposite side x torque)	24 mm x 55 N.m (550 kgf.cm)	26 mm x 55 N.m (550 kgf.cm)

4.Manifold gauge

•Because the pressure is higher for the R410A type, the conventional type cannot be used.

Table 6 Difference between R410A and conventional high / low-pressure gauges

	Conventional gauges	R410A gauges
High-pressure gauge (red)	-76 cmHg - 35 kgf/cm3	-0.1 - 5.3 Mpa -76 cmHg - 53 kgf/cm3
Low-pressure gauge (blue)	-76 cmHg - 17 kgf/cm3	-0.1 - 3.8 Mpa -76 cmHg -	38 kgf/cm3

•The shape of the manifold ports has been changed to prevent the possibility of mistakenly charging with another type of refrigerant.
