I ordered this replacement set after accidentally damaging my first one. These are working perfect. My ac is working just as intended, and I had a nice cool and comfortable night thanks to these.

  • Smaller 1/4in line a bit thin
Size: 25Ft 1/4" and 5/8"
1/4 in line a bit thinner than I prefer. Can work, just remember not to torque past 10lbft (1/4 turn past hand tight or so) and no mineral oil. The other 5/8" was very good quality
