Linesets 61220501l Copper Ac Lineset 3/8x3/4 in 50 Ft

Product Description

The LINESETS 61220501l is a pre-insulated copper refrigerant lineset designed for split-system air conditioning and heat pump installations. It consists of two copper lines: a 3/8 inch OD liquid line and a 3/4 inch OD suction line, running 50 feet in length. The suction line is insulated to prevent condensation and heat gain. Plain ends allow field flaring or brazing, and the factory-formed 90-degree bend simplifies routing at the unit connection points. Licensed HVAC technicians install this lineset to connect the indoor air handler or evaporator coil to the outdoor condensing unit.

This lineset is suited for residential and light commercial split-system installations where a 50-foot run is required between the indoor and outdoor equipment. The 3/8 inch by 3/4 inch line sizing is a common combination for mid-range residential cooling and heat pump systems. The plain end configuration gives the installing technician the flexibility to terminate connections using standard flare fittings or brazing, depending on system requirements and local code.

Key Features

• 50-foot length suitable for longer residential lineset runs
• 3/8 inch OD liquid line and 3/4 inch OD suction line in a matched pair
• Copper construction for reliable refrigerant containment and long service life
• Suction line insulation reduces heat gain and prevents condensation on the low-pressure side
• Plain ends allow field flaring or brazing per job requirements
• Factory 90-degree bend eases connection routing at indoor or outdoor equipment

Compatibility

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

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification. De-energize and recover any residual refrigerant from the system before disconnecting or replacing existing linesets. Protect plain copper ends from contamination and moisture during handling and installation. Support the lineset at regular intervals per manufacturer and local mechanical code requirements to prevent vibration damage over time.
