1979-93 Mustang A/C Manifold Service Attachment w/ Charging Port by 5.0 Resto

The valve leaked and would not stop with a little tightening. I had to fully unscrew it, and then tighten it back down to seal. It's been awhile now and there's no leaks. (checked with sniffer)

Install was easy and I had converted my system to 134A so I was glad to see the insert wasn't in this manifold. And it came with the o rings!

This is a perfect replacement for the original, but in addition has some benefits that some may find helpful.

The original manifold fitting has a "half moon" insert inside where the accumulator/drier hose goes, and the hose itself has a corresponding "half cut" so the hose can only fit inside one way (see the right fitting in my photo). Most aftermarket driers do not have that half cut, meaning you have to cut away part of the hose to fit - even LMR's is this way, as mentioned in one of the reviews for it. Leaving the drier open and exposed to air is bad, and cutting it is an invitation to getting metal shavings in the system, so I bought this manifold fitting with the hope that I won't have to do any hose cutting.

The good news is that this fitting does not have the half moon insert inside, meaning any aftermarket (or OE) drier will fit without cutting! Also, note that the charging port is for R134a, so if you're doing a conversion (as I guess most owners will be), you don't need to buy a separate adapter fitting.

I bought this as my 91 mustang was leaking Freon from the old valve, excellent part and very easy to change. I'm glad to have my air conditioning back.

Thank you

this part was not even offered at my local dealership. I'm very thankful that Late Model had this part, it beats buying a new compressor.
