# 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.

Worked perfectly

They helped with removing the a/c fittings on Gm cars and trucks

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.

Even being a 35 year automobile master technician, I never owned a service port socket. Until recently, I had little use for one. It seems that these are becoming a common a/c failure. When I did need to change one in the past, it was a lengthy undertaking trying to find a socket that would fit these odd ports. Is this set cheap? Yes. Is the quality cheap? Yes again. If you use it on aluminum air conditioning lines, it won't matter. Since purchasing this set, I've used it 5-6 times and it's worked perfectly. Snap-on wants $79 for one of these sockets. Don't pay the rape van! Get this instead!!

If your a tech for a DYI that does HVAC a lot you could add these to your box but if your able to get a wrench on the L and H ports then that's fine as well. I'm sure as the engine bay "shrinks" these sockets will gain their usefulness has even getting an open end or small crescent wrench on the ports will be impossible without having to remove a power steering pump or alternator just to get the hidden high side port.

I never could change ports properly. Now, I can.

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