Our take on the MRCOOL DIY 5th Gen 35 Ft. Pre-Charged Quick Connect Line Set with DIY Pro Cable, 1/4" x 1/2", for DIY 18K Mini Split Indoor Air Handler

This is the refrigerant line set that connects a MRCOOL 5th Gen DIY 18K air handler to its outdoor condenser. It comes pre-charged with R-454B and uses Quick Connect fittings, so the connection needs no vacuuming, charging or refrigerant certification. The 35 ft length suits longer runs between indoor and outdoor units, and the kink-resistant, leak-proof construction is built for a lasting seal. It only fits the 18K 5th Gen DIY air handler with 1/4" liquid and 1/2" suction ports, so check your model before buying.
