by Polyaire
$105.00

 

The use of 15% silver solder is recommended when brazing tube or fittings for use with R410a or other high-pressure refrigerants. A silver brazing flux can be used and is available at our store.
 
R410A has a 60% higher operating pressure than R22 thus requiring a thicker wall copper tube and significantly stronger (R410A) copper fittings. The minimum allowable tube wall thickness is 0.81mm + except for 3/16". Please see title for actual thickness specified as outer diameter.
