Part number for this low pressure AC line:
 
Been looking through the parts fiches but they seem to show the same part for the drier as for this line. I Can't make heads or tails of it really.

So, anyone know the part number? I may just take it off and goto Napa tomorrow to see if they can make me a new one.

(this is the low pressure line that runs from the drier to the AC compressor)

Everything I've found is from the drier to the box also.Cant understand that.It's a simple bolt on hose.If all else fails you could try this.http://www.idqusa.com/proddetail.php?prod=325 Our '99 would loose it's freon in 2 weeks after a charge but after this it's been a year and still have ac.I didn't believe it either!

I prefer to avoid using any sort of sealant like that, most of those work of off a principle of plugging up where a hole is during an exit. The orifice tube also tends to mimic a leaky hole.

But from my count there seem to be about 4 little pinhole leaks, so its probably better to replace the hose.

The drier has the line to the box integrated into it, so you can find that part as an aftermarket replacement, and since the orifice tube is a common failure as well there are aftermarket replacements for that.

However checking rockauto and a couple of other places it seems that those are the only two aftermarket replacements, no other AC lines are available.

Then when you look in the parts diagrams it kinda shows this hose, but it seems to list it as being the accumulator/drier, which either means the only way to get it is with the drier, or that its hiding out in the parts diagrams and just isn't clearly labeled. (pretty typical really, makes finding odd parts hard).

Ok the part number for the 99-01 is 55116501AB called "LINE, A/C Suction":(part #23 in this diagram:)

However the system changed in 02 and instead of using a orifice tube it uses an expansion valve, so all the parts are different:

Well it looks like I found a place locally that is going to put some new crimps on and replace the hose, hopefully I get the call back sometime this afternoon and pick up the repaired hose.

So this is more for information for others, really it should go in my WJ build thread, but whatever.

So I was tracking down an AC leak when I determined that the AC line pressure hose from the accumulator to the compressor had several pinhole leaks that were leaking pretty bad. The cheapest new hose(which was readily available from my Jeep dealer where I have my business account still) would have been about $83 and I would have had to make a drive to denver to get it(3 hour roundtrip plus the better part of a tank of gas). Local dealers in my town wanted like $120 for the line, and there are no aftermarket lines made.

Napa makes AC lines and hydraulic hoses, but does not have the bolt down fittings that our newer hoses use, and they didn't have anything else that would help, I checked with parker supply who does lots of hoses and hydraulic fittings, they had a 5/8 compression fitting that could have worked, but at $55 for the two fittings and some new hose I decided it wasn't worth the risk it would leak(the aluminum AC line is slightly smaller than 5/8, and it not a smooth mating surface and can be out of round too).

Went and tracked down a third shop, guy knew what needed to be done and had the parts, cut off the old crimped fittings put new ones on and replaced the rubber hose, total cost $35 :mrgreen:

Got it in and recharged the system, now I wait to see if it leaks down!

Man its always nice to find a shop that knows what they are doing, can get it done right away, and charges a reasonible rate, when you find those shops you gotta keep em open by sending them what business you can.
