Should line sets for R-410A have a greater wall thickness than for R-22?
Why should they? They will withstand MANY times the maximum pressure of R410A.
If all else fails....Try reading the directions!
Tell it like it is and let the chips fall where they may.
Any views or opinions stated here are strictly my own.
What those guy's said.
Ignore the part about CO2, in this link is a table of ACR tubing pressure ratings:
Wow, I didn't know the safety factors were that large. What are the maximum pressures for R-22 and R-410A?
For R410a, discharge pressures can be as high as 450 PSI, but that's an unusually high pressure.
What's your concern here?
