R-12 To R-134a Gauge Adapters

R134-a gauge adapters screw onto your old R-12 gauges to convert them to R-134a gauges.  The gauge adapters will allow you to adapt the low side, high side, and fill tank hose from any R-12 gauge set. 

The adapters have quick release couplers for the low side and high side for any R-134a air conditioning system.  These adapters are the best way to keep your gauges ready for both types of refigerant.  The couplers can be screwed onto the R-12 hose and removed in seconds.
