J 41425 A/C Line Repair Kit
The A/C line repair kit is the recommended repair for all A/C lines that require repair caused by rub through, collision damage, or system leakage. In a
situation that the A/C line has visible damage in a bend area, the A/C line needs to be sectioned. Sectioning the line will obtain the original line shape to
avoid vibrations or possible rub through.
Straight Line Repair
1. Recover the A/C system.
2. Locate the repair area.
3. With a tubing cutter, cut the damaged line for repair.
4. Clean any burrs or grease at least 3/4 of an inch from the A/C line using the cleaning pad provided in the kit.
5. Prep the A/C line to be repaired using the 10k prep sealant.
