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.
