Aciq LS381183850 Insulated Line Set 50 Ft 3/8 X 1 1/8

Product Description

The ACIQ LS381183850 is a 50-foot pre-insulated refrigerant line set designed for connecting outdoor condensing units or heat pumps to indoor air handlers or evaporator coils in split-system HVAC installations. It features a 3/8-inch liquid line and a 1 1/8-inch suction line, both constructed from flexible copper tubing. The suction line carries 3/8-inch-thick insulation to minimize energy loss and reduce condensation buildup during operation. Licensed HVAC technicians install this line set as part of new system commissioning or replacement work on larger-capacity split systems and heat pump applications.

This line set is suited for residential, light commercial, and industrial split-system installations where greater refrigerant flow capacity is required. The 1 1/8-inch suction line diameter accommodates higher-tonnage systems that demand larger line sizing. The 50-foot length provides enough run to handle installations where the outdoor unit and indoor air handler are separated by a significant distance, including multi-story buildings or units placed on rooftops or remote pads.

Key Features

• 50-foot length suitable for extended runs in larger residential and commercial installations
• 3/8-inch liquid line copper tubing sized for high-capacity refrigerant transfer
• 1 1/8-inch suction line copper tubing for systems requiring greater refrigerant flow
• 3/8-inch-thick insulation on suction line reduces condensation and limits heat gain
• Flexible copper construction allows smooth field routing around obstacles and through walls
• Pre-insulated design reduces field labor compared to field-insulating bare line sets

Compatibility

Designed as an OEM-style replacement or new-installation line set for larger-capacity split-system air conditioners and heat pumps requiring a 3/8-inch liquid line and 1 1/8-inch suction line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes and the equipment manufacturer's specifications. Recover and reclaim any existing refrigerant charge before disconnecting old line sets, as required by EPA Section 608 regulations. Inspect all flare or braze connections for leaks after installation and before charging the system. Avoid kinking the copper tubing during routing, as deformation restricts refrigerant flow and reduces system efficiency.
