Selected User Reviews For Dorman 800-640 Line Splice For 5/8 In. Aluminum Lines
A new line installed at a dealer costs around $1500, plus any other issues they discover and try to scare you into paying for. br>br>I ordered 5/8 OD and received 5/16 OD instead. With Amazon, there are no issues with returns or exchanges. That is why I purchase so frequently from them. br>br>The trick with this splicer/coupler is to have access to the leak as well as enough room to cut out the "bad" section of line and tighten the splicer with a wrench. Note that this splicer is for the aluminum/hard line, not the rubber hose line. br>After completing this repair and charging the system, a leak in the compressor developed, which was repaired with heavy duty sealer refrigerant. For the past six months, everything has stayed put.
I could tell right away that the splice fitting's mechanics were suspect, as it leaked horribly even at the recommended 18 ft/lbs. The segmented brass ferule seemed to bunch the sleeve seals in place, despite all of the pieces needing to be perfectly aligned with no side or angle forces. In any case, they didn't seal, as did many other reviews on this site. They may have stopped leaking after I cranked them down to closer to 90 ft/lbs, but I'm not confident in them. Given that a larger piece of aluminum won't corrode as much as brass, and brass fittings can withstand 400 psi, I'm kicking myself for not using one on the low-pressure side of the system. Titan Compression Fittings are made of stainless steel and are available in a variety of sizes.
It worked perfectly and I was able to save over 1700 dollars. In a 2012 Acadia, the dealer wanted to race the rear AC line for $900. Installing it was a breeze. It's been about three months now, and there have been no problems.
The line comes in two sections and must be installed using a $1500 tool that I didn't have and certainly wasn't going to buy. I had seen these line fittings for repairing lines and was a little skeptical if they would hold up as the high side A/C lines can reach upwards of 400 PSI. Well after using this connector with new lines, I'm more than happy with the way.
Although it appears to be a good idea, when the brass color was tightened, it broke inside and slipped off. I was crossing my fingers that it would work. I own an auto repair shop, so it's not like a regular person did this and simply overtightened the bolts. He was a technician with more than 20 years of experience.
Otherwise, the line will leak unless it is perfectly straight and round. I got through four of them before giving up. Two of them snapped in half while attempting to tighten it to stop the leak.
4 months ago as a quick fix, and I honestly didn't expect them to last that long. So far, everything has gone swimmingly. Last year, I had to cut both of my ac lines on the side of the road to make an emergency repair. I categorized these into three categories. 4 months ago as a quick fix, and I honestly didn't expect them to last that long. These are on my semi, and my truck works in a harsh environment for 10 hours a day, six days a week. So far, everything has gone well; I'll update this review if and when they spring a leak. br>br>9th Update- 17 - It's still the same as day one.
The main component of the product was missing when it arrived.
