AC Compressor 90 degree fitting

[jakg104]

Hi folks,
I'm in the process of retrofitting conventional AC in my Euro 86 911.

Will be using a 964 front condenser with a Rear fender condenser and need to build hoses for the install. I'm running into an issue finding the 90 degree fitting that goes onto the compressor.
It seems to be a #10 90 degree fitting that has a 22x1.75 thread pitch. I can find 22x1.5 thread pitch, but cannot for the life of me find a 1.75 thread pitch.

Searched coldhose, etc and the other sites that sell pieces...

Does anyone have any suggestions for this? Pic attached for reference


Thanks in advance!

So your problem here is that you are taking for granted that the Suction and discharge fittings on your 10P15C nippondenso are metric. They are not and none of the A /C fittings are metric, they are all SAE. The suction fitting you are looking for is a 90’ female o-ring #10 7/8 -14.
The part # is a 14210 in a Four seasons and Murray and will also cross over to other manufacturers as well, just google it and it will come right up.

One of the best A/C tools I have ever invested in was the portable A /C hose crimp kit, I can’t count how many single and full custom hose kits I have made with this thing over the years, it is worth it’s weight in gold and paid for itself the second full hose kit I made with it.

AH!! ok! This is awesome information Richard, thank you! Alright, now will continue the process.

Which brand is that AC crimp kit? Good point in investing in one... Will definitely give me the flexibility to make them ourselves and then if we run into a snag, can edit onsite..

Also do you have a preference of hose brands or places to buy for the 911?

Thanks again!

One bit of advice. When you go to tighten that fitting on the compressor, be judicious with the tightening. It is a large fitting and the wrench you need to use, makes it very easy to over tighten it.



It is real easy to over tighten it and damage to o-ring as seen above. That will cause a leak and it is hard to find, but easy to fix.

Great point. Will do, thank you!

MasterCool Hydra Krimp 71500 is the kit, I paid around $400 plus shipping and tax IIRC. They have gone up pretty substantially since then. As far as hose manufacturers I either go with Parker Futura or Goodyear Galaxy. They can be sourced from many internet sellers.

Excellent, thanks Richard. I appreciate it.

Any difference between the $10 HNBR set and the $50 ?




Probably all made overseas, might even the exact same product with a different label.

This one has really high review count as well.

I bought this one and it’s worked perfectly. No need to spend $50 on $2 worth of parts.

Thanks for the info on the o-rings, one box is enough for several lifetimes for us DIYers !

So, what's the torque spec on that besides yea tight ?

Appear to be on the order of 10-ish ft lbs, from what I read on the Interwebs, these fittings are meant to be handled with care !

I would be surprised if the run of the mill shop does so.
