I have an extensive sae/metric socket set. what makes this socket special?

I also have a large socket collection but was not able to remove the Chevy truck air conditioning without this cheap socket. When you compare this one to my 16MM the flats are longer and the corners are more rounded on this cheap one. I have put this socket in my drawer in the back corner as I believe it will only work for a few times and does not fit a fastener correctly. I do not understand why they did not just make these air con fittings use standard or metric tooling.

What size octagonal nut does this fit? I need something for a 16mm octagonal nut

this socket fits on a a/c line schrader valve valve

Is this socket required? NO! This socket is required only if the valve is located in an area that restricts use of standard adjustable wrenches.

This socket is required if you want to remove the high side AC service port valve correctly and not be a cheese d i c k. Using an adjustable wrench is a good way to strip/round the octagon shaped fastener. Oh and octagon means 8 sided (I assume anyone who would suggest using an adjustable wrench didn’t finish grade school.) if you damage the AC service port there’s a good chance your AC gauge fitting will not attach properly to the fitting.

If you want to change the high side A/C fitting on a lot of GM vehicles, this Mastercool socket is exactly what you're looking for. It fits the valve perfectly and with some care (the lines are easily twisted, so support the line while attempting to remove the old fitting) will let you easily change your old fitting out for a new one. Used mine a few times now to replace the dreaded ball style high side fitting found on many GM vehicles with a serviceable Schrader valve instead (GPD 5811696 is an example for anyone looking for one) with no issues. Well worth picking one of these up, especially if you do a lot of A/C work or simply want to replace a bad fitting on your own vehicle.
