Hey guys my ac drier line recently broke and being in the middle if summer, I need this repaired pretty badly. I found a site that makes customs ac drier hoses (cause oem cost way too much) and was wondering if anyone knows what size fittings go on the end of the hoses.

I pretty much need to figure out what size fitting connects to the condensor / evaporator.
I know its a female o-ring fitting.

Here's the site I plan to buy it from
http://www.coldhose.com/custum-ac-hose.php

 

First of all, wow, great find on that site!

The important question is do you have a MANA or Denso system? There are different systems based on this.

MANA systems typically had a black dryer and the Denso typically had silver. IIRC one uses metric and the other AN.

 

Uhhhh....you want to attach a hose to the dryer? The pad fittings on the drier are totally specific to the dryer type. Nobody is gonna stock those fittings.

On the condenser end, it is #6 tubing, and the MANA system has metric a metric nut, and the Nippondenso system is standard AN

Take it to a local shop that specializes in A/C work....they can make hoses, and they can make sure the fitting fits the condenser before they make the hose....but I still don't know what you're going to do on the drier end of things.

If the break was reasonably clean, you might also be able to just repair the tubing with a Swagelok fitting.

 

Or just get a new line from Mazda. They're not terribly expensive. Or get a good used one.

I have a silver drier, so I'm guessing it's the denso system, can't I buy a new drier and make a new line for the condenser?

Can anyone else confirm we use a #6 5/8 fitting?

 

As stated, you are very unlikely to be able to order a custom line from the drier to the condenser because of the custom fitting on the drier end of the line.

You can pick up a line in the classifieds for very little.

 

a new drier is relatively cheap.

 

New driers are like $20 for the Denso.

 

I researched that site and others when I was hoping to put ac back in the darkside 7. Have you thought about just welding a connection? how badly broken is your line??

 

It is a neat site. Unfortunately (as I discovered a few months ago) they do not have male metric AC fittings, which is a problem for MANA systems because the use metric connections. The drier connections are also highly custom too (on both Denso and MANA).

For those with a Denso system, a custom line would be possible for a v-mount AC line relocation (bending the stock lines only really works for the small drier one), but, again, the drier connections will mean that the custom lines will have to go inline with the stock lines to relocate them.

 

Well, a new drier is like $15-$20 and after 18 years of use, a new drier isn't a bad idea.
I tried searching for ac shops, but I can't find any.

You can get universal male o-ring driers in #6 fittings/hose,
but the real question is...

What size fitting does the condenser require?
I may just go buy a #6 fitting and see if it plugs in.
Then have the site make me a hose.

 

Yes, but will the new drier fit? If you look at the stock solution, it has pretty clever line routing with very little clearance.

You will also need a custom line from the drier to the compressor if you do this. Or, at least from the drier to the end of the stock hose attached to the compressor.

I am really not sure about your goal here (or perhaps I missed something) - even from a dealer, a new line will be cheaper than the route (no pun intended) you are taking.

 

I believe the line itself is $80 from mazda

the custom hoses are $25 each, and drier $20

So, it's really the same price... but I get 2 new hoses and a new drier vs 1 new hose.
Plus, I won't have to worry about the other drier line breaking due to its age.

 

Fair enough. Let us know how it works out.

I was going to go a similar route but fitment issues (among other things) stopped me.

And remember, the stock hoses are much lighter and easier to route than the custom hoses, which are pretty bulky.
