Cerro 612203060009 Ac Line Set 3/8 Liquid 3/4 Suction 30 Ft

Product Description

The CERRO FLOW PRODUCTS INC 612203060009 is a pre-insulated copper AC line set designed to connect the indoor air handler or evaporator coil to the outdoor condensing unit in a split-system air conditioning or heat pump installation. The set includes a 3/8-inch liquid line and a 3/4-inch suction line, running 30 feet in length. The suction line is wrapped in 1/2-inch-thick black insulation to minimize heat gain and prevent condensation. HVAC technicians use this line set as a ready-to-run solution that eliminates the need to measure, cut, and insulate individual copper lines on the job site.

This line set is suited for residential and light commercial split-system installations where the indoor and outdoor units are within 30 feet of each other. The 3/8-inch liquid line and 3/4-inch suction line sizing is common in standard residential cooling systems, particularly those in the 2- to 5-ton capacity range. It is typically installed during new construction, equipment changeouts, or system upgrades where existing line sets are damaged or incompatible with new equipment.

Key Features

• 3/8-inch liquid line and 3/4-inch suction line in a single pre-paired assembly
• 30-foot length suitable for typical residential split-system runs
• 1/2-inch-thick black insulation on the suction line reduces heat gain and condensation
• Pre-cut length reduces field fabrication time on installation or changeout jobs
• Copper construction provides reliable refrigerant-grade performance

Compatibility

Designed as an OEM-style replacement or new-installation line set for residential and light commercial split-system air conditioners and heat pumps requiring a 3/8-inch liquid line and 3/4-inch suction line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification. Shut down and recover all refrigerant from the existing system before disconnecting any line set connections. Inspect both ends of the copper lines for deformation before flaring or brazing connections, and ensure the insulation is continuous and sealed at all fittings to prevent condensation. Follow the equipment manufacturer's instructions and local mechanical codes for proper line set routing, support spacing, and refrigerant charge procedures.
