More About Line Sets

Refrigerant line sets are flexible copper pipes that connect the outdoor condenser or heat pump to its corresponding indoor unit. They are composed of two types of lines, a suction line and a liquid line, with the suction line being the larger of the two pipes. Line sets can be cut with a tubing cutter to satisfy each individual installation requirement.

PexSupply.com offers two types of refrigerant line sets. Flared refrigerant line sets are used with mini-split systems and both the suction and liquid lines are insulated. Our selection of standard refrigerant line sets have plain straight ends where only the suction line is insulated.
