No. the pressure are different, r22 runs at a fairly low pressure and you shouldn't be worried about blowing your gauges, but you won't be able to determine your super-heat or sub-cooling. for a about $100cdn you can buy the right gauges.
Is r-22 Freon compatible with r-134a freon?
No
Not unless you like the idea of destroying your AC system.
No, you should not use an R22 manifold gauge set for R410A. R410A operates at higher pressures than R22, and using an R22 gauge set could lead to inaccurate readings and potential equipment damage. It's essential to use a manifold gauge set specifically designed for R410A to ensure safety and proper functionality.
Wal-Mart do not have r22 freon, this is a false ad.
