Relocating the air conditioning charging valves, need the valves.

R12 or 134a??

I can go either way. What have you got?

Most good A/C repair shops can fabricate the hoses and fittings that you need. I relocated my charging ports behind the main surge tank.

Doug,

what you are looking for is called an in-line charging port. Nostalgicac.com has a good selection for both R 12 and R 134.

You do understand that the hoses in the rear are high side only. The low side is between the evaporator and the compressor and is normally where charging by vapor takes place. You cannot charge into the high side with the compressor running.

I have only found the crimp to crimp like you posted. The simplest would be to use a male to female threaded insert but so far I have found none and only in 134a. No R-12.

There is a crimp to female thread.

I've never charged a system without the compressor running. I'm sure it can be done but is beyond my pay scale at the moment.

Nostalgic has R-134a versions straight and 90 degree, the ports are different, but you can also get R134a to R12 charge port adapters.

Perhaps consider extensions to the existing compressor ports to put them alongside the coolant tanks and just under the engine screen for easy access?

As Julian suggested, I moved mine to a small bracket just behind the removable engine access cover, on the upper passenger side corner. No more laying on the floor to attach the charging unit!

I also wanted to re-locate the charging ports to make that task easier.

I added T-fittings to both lines coming off the compressor and connected them two fittings installed in the firewall.

For the firewall fittings, I used the T-fittings that are now usually screwed into the back of modern compressors. You will see I capped off the outlets that usually fed in to the refrigerant hoses.

all I have to do is pull the upholstered cover and there they are.
