NO-VAC™ QUICK CONNECT® LINE SETs allow you to connect indoor and outdoor units simpler, faster and safer.
NO-VAC™ QUICK CONNECT® LINE SETs are an�-kink and pre-charged with refrigerant; suitable for most MRCOOL® installa�ons.
NO-VAC™ QUICK CONNECT® LINE SETs are a double-sealing system with a unique automa�c safety valve that releases the
refrigerant only when the indoor and outdoor equipment is connected and sealed, thus avoiding any risk of leakage.
NO-VAC™ QUICK CONNECT® LINE SETs - no need to vacuum, no need to add refrigerant.
