Buy Auto Supply # K13001 - High & Low Side Octagon Socket for R134a AC Service Ports 3/8" Drive - Aftermarket Parts fit 98134 & 98234

I needed to replace the high and low ports on my 2001 Suburban AC. I decided to spend the money and buy the proper sockets to remove the ports instead of messing with pliers. The sockets fit great and worked great and arrived as promised. The company that supplied them has a great product line of AC valves and caps, automotive light bulbs, etc. Very Happy and these were much less expensive than buying at a local auto parts store. I recommend buying them in advance so you have them in your tool box.

Decent quality socket for the home A/C car repair person. Fits nicely on the fittings and worked great

Yes, octagon. Very annoying but necessary to change the service ports.

If you need to replace the high side schrader valve on a GM that has the schrader valve incorporated in the high side fitting you need these sockets. It may be possible to find a 12 point that fits or get it with a wrench but these are made for the job and make it easy.

Havent used them yet they are lil loose on the fitting look cheaply made

Works like a charm

fit perfect on valve

These are nicely made and finished, with no apparent plating or other defects. Each is deeply stamped with a large "R134a" and either "H" or "L" to clearly indicate the intended application.I've not seen nominal dimensions for either socket.The low-side socket measures 12.70 .. 12.74 mm across the flats (depending on which pair of flats you measure), but I've not yet used it on a real service port to check fit.The high-side socket measures 15.69 .. 15.73 mm across the flats, and is an appropriately snug fit to an original Chrysler high-side service port.
