Schrader Fittings w/ R-410a

Schrader Fittings w/ R-410a

Schrader Fittings w/ R-410a

(OP)
What are your opinions of using Schrader fittings on a R-410a system in general and more specifically for a place to mount pressure switches vs brazing.  The idea is - in a tight package, it is easier to replace a defective pressure switch that's fitted to a Schrader fitting than tear the unit apart such that one can un-braze and re-braze the switch.

Any advice would be much appreciated.

Thanks!
Bill

RE: Schrader Fittings w/ R-410a

Schrader fittings are used all the time for pressure switches and the schrader fittings are brazed especially for 410a with its hi pressure system.

RE: Schrader Fittings w/ R-410a

Make sure the fitting's o-ring seal is compatible chemically with the refrigerant material.  The other thing is to watch for vibrations.  A heavy switch on a simple schrader fitting will break-off quickly.  Otherwise is it should be fine to do so.
