Binary Switch w/ R-134a Discharge Port 7/16"

This adapter will allow you to add a high low pressure switch and a R-134a high port to a stock R-12 system.  The Tee fitting screws onto the factory R-12 high side port converting it to a charge port for R-134a.  The adapter requires the removal of the stock valve core, the core can be removed with a valve core removal tool.   The kit includes a new plug for the high low pressure switch with 18 inches of wire.  The wire get spliced into the compressor coil wire.

• The switch operates at the following pressures:
• Low pressure cutoff 28 PSI
• High pressure cutoff 398 PSI
• High pressure on 312 PSI

There are two different ports on the factory R-12 discharge size.  This adapter is for the larger size.  If your vehicle uses the smaller port you will need part number 119-9905.  If you are unsure which part you need use the cap off of the low side to test your vehicle.  If the stock R-12 low side caps screws onto the high side this is the correct part.  If the high side port is smaller then the low side you will need PN 119-9905.
