Linesets 61420501l Copper Ac Lineset 3/8 X 7/8 in 50 Ft

Product Description

The LINESETS 61420501l is a pre-formed copper refrigerant lineset designed for split-system air conditioning and heat pump installations. It consists of two copper tubes — a 3/8-inch OD liquid line and a 7/8-inch OD suction line — supplied at 50 feet in length. The suction line is insulated to minimize heat gain and prevent condensation. Both ends are plain-cut, and the assembly includes a factory 90-degree bend to ease routing through tight wall or ceiling penetrations. Licensed HVAC technicians install this lineset as part of a new system installation or a direct replacement during equipment changeout.

This lineset is suited for residential and light commercial split-system applications where a 50-foot run is required between the indoor air handler or evaporator coil and the outdoor condensing unit. The 3/8-inch by 7/8-inch line size is a common configuration for mid-range cooling capacity systems. The factory 90-degree bend reduces field bending and helps maintain tube integrity at directional changes during installation.

Key Features

• Copper construction for durability and refrigerant compatibility
• 3/8-inch OD liquid line and 7/8-inch OD suction line in a matched pair
• 50-foot length suitable for standard residential split-system runs
• Suction line insulated to reduce heat gain and condensation
• Plain ends for field connection via brazing or flare fittings
• Factory 90-degree bend included for easier directional routing

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 7/8-inch line size configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes. Disconnect and lock out power to both the indoor and outdoor units before making any refrigerant line connections. Plain ends should be connected using accepted brazing procedures or approved flare fittings; keep tube ends capped until final connection to prevent contamination. Ensure proper support and clearance along the lineset run to prevent vibration contact and physical damage to the insulation.
