Compression fitting on hard line

emsvitil on Thu September 16, 2010 4:12 PM User is offlineView users profile

Year: 1986
Make: Toyota
Model: Pickup SR5
Engine Size: 2.4
Refrigerant Type: R12
Ambient Temp: NA
Pressure Low: NA
Pressure High: NA
Country of Origin: United States

I have a high side pressure line (drier to evaporator) that was installed incorrectly 24 years ago by the dealer when I bought the truck. (A section was installed above a wiring harness instead of below the wiring harness, and the harness wore a hole into the line).


Anyway, why couldn't a high-pressure compression fitting (1000psi) be used to splice the line at the hole? I don't see how it would leak....

Don't ever intend to take it apart there, and the fitting is only about $3.......

That's what the inline filters use---you are directed to cut the line apart and install a compression fitting as part of the in-line filter. Personally, I prefer the swageloks-- work really good.....

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

As GM Tech stated, the Inline Filter is designed to do just that. To couple into the aluminum line with compressor fittings.

Cool....

Pity it's already after the filter/drier.......

And if you have my typical luck, I suppose the hole is far enuff from the filter that you could not cut the line just past the hole and still have enuff slack in the rest of the line to put a new fitting on the line where you cut it and still reach the filter connection! Bummer for sure if you cannot do that. You could use some fittings and the same size tubing to extend the line enuff to reach the filter. That might be simpler/cheeper than replacing the complete tubing run.

My heart goes out to you!

Ed -- I just had a brain fart! Am wondering if you might have misunderstood the other guys that answered you. What they were saying is to use a coupling to just make a splice in the line where the hole was. That would be mucho better than what I was thinking in my previous answer for sure. Whether or not you could do this depends on where the hole is in relation to the filter -- you would have to have enuff room for the fittings. If that won't work, you could do what I suggested in my first post. You would have to find a piece of the same sized tubing to use with the fittings.

You get about an inch of length with the coupler.

That, plus the line is convuluted (you can gain a little length by slightly bending the line and taking a slightly different path) will get me what I need to get rid of the bad section.....



thanks

It took 24 years to discover that problem? Thought I was slow.

It took awhile to wear enough of the tubing away to cause a leak.........
