Review on 🔗 Dorman 800-641 Line Splice - Quick Fix for 3/8" Aluminum Lines with Enhanced SEO by Tony Elliott

I used this to fix a leak in my Trane AC coil at home. It worked! Pressure retention greater than 200 psi on top of spiral tubing (3/8 inch diameter tubing). Be sure to cut the tubing square and insert it fully into the fittings, first without tightening the green washers, then opening and inserting the washers and tightening to specification. Don't overtighten. Getting a new compressor would be a long wait, not to mention expensive. called an AC repair technician to actually charge it.
