Why it matters
The TAUROX 50 ft Line Set, 1/4 x 3/8 in is a pre-flared, insulated copper line set, 50 ft long, with a 1/4 in liquid line and a 3/8 in suction line. That pairing suits most 9,000 and 12,000 BTU systems (and some 18,000 BTU ones); always match both sizes to your condenser's service valves.
Most systems ship charged for a set line length, often 16 or 25 ft. Within that length no refrigerant needs adding; longer runs need extra charge added by a technician, and every open-flare connection needs a vacuum pulled before the valves are opened.
Both lines are insulated; outdoors, protect the insulation from sunlight with a line-set cover.
The listing gives dimensions of 18.5 inL x 18.5 inW, a shipping or unit weight of 8.28 kg, condensate drain hose， pipe insulation straps, interconnecting cable, wall filler putty, decorative wall cap in the box and copper construction.
