In a customer's Ford E-150, a hard line had rubbed against the spring perch. It worked perfectly near the rear tire on the driver's side. br> My Robinair 34700z maintained a good vacuum. I charged up the system and turned it on. No leaks at 250 psi. Here's how I went about it: br>br> br>Loosened the clips holding the line in place and gently repositioned it to make repair easier. br>I used a Scotchbrite pad to clean the area. br>Deburred the ends and cut out the rubbed/damaged tubing (approximately 2" section). Brake parts cleaner was used to clean the line after it had been bent. PAG oil was applied to the seals (generously). br>I tightened until the compression ferrules were snug, then a 'touch' more to seat them. You can feel the aluminum's lightness and flimsiness - It takes very little to over-indulge. It needs to be torqued.
Re- No chance of rubbing on anything thanks to the secured line.
The line was cut, the fitting was installed, and the area was vacuumed. The system was refilled. This was done last summer (2020) and has yet to leak a drop. Product that is both cost-effective and labor-saving.
Update: After a few months, a small R134a refrigerant leak appeared, but not large enough to render the cooling system inoperable. br>br>So far, it's holding on to a 2006 Chevy Suburban high-pressure rear A/C line, which rubs against the heater hose crimp and eventually cuts a gash, allowing all refrigerant to escape from the entire A/C system. The dealer estimated that the repair would cost around $1000, but this splice will fix the gash. To remove the damage, use a close clearance line cutter (one with thumbscrews, rollers, and a cutter wheel) and clean the line thoroughly until it is shiny. It's crucial to know your torque specs. Use a standard socket torque wrench and crowfoot open end extension to save money. If you don't adjust your torque setting (which should be lower with the crowfoot extension), you'll end up overtorquing. For formulas and online calculators, look up "crowfoot on torque wrench" on the internet. Alternatively, if the crowfoot extension will fit, turn it 90 degrees and apply the specified torque without adjusting it.
This helped me repair a leak in my Trane air conditioner coil at home. It had an effect. On the high side of the coil line (3/8 inch diameter line), maintain a pressure of over 200 pounds per square inch. Cut the line square and seat it all the way into the fittings, then tighten without the green washers first, then open and insert washers and tighten to spec. Make sure you're not overtightening anything. It would have taken a long time to get a new compressor, not to mention the cost, so I hired an AC repairman to do the actual recharging.
The only issue I had was that this splice connector is very bulky, measuring about an inch in diameter, which made it difficult to stop the leak in my 3/8" AC line. If you have AC lines that are too close together or too close together, you may need to find a way to separate the leaky line from the other lines to give your splice some breathing room. Aside from that, this is an excellent product; you will not find a better price for this level of quality!.
My air conditioning broke down two hours into a nine-hour drive home. I found the spot on the rear spring hanger where the hose for my rear AC had rubbed through. I did some research online and discovered that the OE part is a single super long unit that runs from the engine bay to the trunk and costs around $500. I was looking for other options when I came across this little coupler. It was an excellent solution. From beginning to end, it took me about an hour. You'll need the proper tools, and don't forget to deburr the ends before installing the gaskets. The product was of good quality, and the instructions were understandable. I hope I won't need to use it again, but I would recommend it to anyone who needs to repair a line.
Update: Four months later, a leaking cooling line necessitated the replacement of all heating and cooling lines. The shop suspects that failed connectors and poor workmanship were also factors! These were used by the mechanic to replace the heating and cooling lines on the vehicle. GMC Yukon with a cooling leak in the back - So far, the connections have held pressure without leaking, and the cooling has been maximized! The dealer used a tool for a different installation method that cost over $1200 just for the tool! If Amazon parts are delivered on time, they are less expensive!.
While replacing the heads on my Jeep, I broke an AC line. When fully charged, I cut out the break and replaced it with this, and it did not leak. This was also at a high pressure level. br>br>It saved me a lot of money and time. And it's a long-term solution.
