Aciq LS38583850 Insulated Line Set 50 Ft 3/8 X 5/8 Inch

Product Description

The ACIQ LS38583850 is a 50-foot pre-insulated copper line set designed to connect an outdoor condensing unit or heat pump to an indoor air handler or evaporator coil. The set includes a 3/8-inch liquid line and a 5/8-inch suction line, both manufactured from flexible copper tubing. The suction line is wrapped with 3/8-inch thick insulation to limit heat gain and reduce condensation buildup during operation. This line set is suited for residential and light commercial split-system HVAC installations where a reliable refrigerant circuit is required.

This line set is applicable across a range of split-system configurations including mini-split systems, conventional central split systems, and heat pump installations. The 50-foot run length accommodates installations where the indoor and outdoor units are separated by a significant distance, such as multi-story residential builds or light commercial applications. Flexible copper construction allows technicians to route the line set through walls, ceilings, and mechanical chases with reduced bending difficulty.

Key Features

• 3/8-inch liquid line and 5/8-inch suction line in a single pre-assembled set
• 3/8-inch thick insulation on the suction line reduces heat gain and condensation
• 50-foot length suits residential and light commercial installation distances
• Flexible copper tubing allows routing through tight or irregular pathways
• Compatible with mini-split, heat pump, and conventional split-system applications

Compatibility

Designed as an OEM-style replacement or new-installation line set for residential and light commercial split-system HVAC equipment, including mini-splits, heat pumps, and conventional split systems requiring a 3/8-inch liquid line and 5/8-inch suction line.

Installation Notes

Installation should be performed by a licensed HVAC technician holding the appropriate EPA Section 608 refrigerant handling certification. The refrigerant system must be recovered and the unit de-energized before disconnecting or connecting line set components. Technicians should pressure-test and evacuate the line set to the required micron level before charging the system with refrigerant. Avoid sharp bends that could restrict refrigerant flow or kink the copper tubing during routing.
