• R410A is composed H-F-C as different as
R22 is composed C-F-Cl.
• Don't use mineral oil when gauge pressure
to prevent contamination.
• Only for R410A.
• Change in service port diameter
• R410A has high pressure as compared with
R22.
• It should be made of materials are not
affected a using refrigerant.
• R410A is used with a polyester oil but a
vacuum pump uses a conventional mineral
oil.
• Need a flare gauge for R410A.
• When using a conventional flare tool,the
pipe extension margin should be
1.0~1.5mm or 1.5~2.0.
• R410A has high pressure as compared
with R22.
• Increase a connecting torque.
• Coat the connection with refrigerant oil
film.If not,leakage is possible because of
the pressure of R410A.
• Coat after flare work on pipe connection.
• Since R410A don't have chlorine, the tester
must can detect Hydrogen.
• High pressure gauge : -0.1~5.3 MPa
• Low pressure gauge : -0.1~3.8 MPa
• Connection port diameter : 5/16 flare
• No oil used
• Working pressure : 5.08 MPa
• Bursting pressure : 25.4 MPa
• Connection port diameter : 5/16 flare
• The degree of vacuum is 5torr(-5 torr from
atmospheric pressure).
• Need a check valve to prevent reverse oil flow
if using a conventional vacuum pump.
*Adding a proper
torque to the pipe
using R410A when
connect pipes to
flare nuts.
• All refrigerants are available as using a
synthetic oil
• High rust resistance
• Long stability over long period time
• R410A, R407C(E), R404A, R507A, R134a,
R12, R22, R502, R500 are detected.
• Available in the range of 0 to 40˚C.
