Linesets 61420251l Copper Lineset 25 Ft 3/8 X 7/8 in

Product Description

The LINESETS 61420251l is a pre-cut copper refrigerant lineset designed to connect the indoor evaporator coil to the outdoor condensing unit in split-system air conditioning and heat pump installations. The set includes a 3/8 inch OD liquid line and a 7/8 inch OD suction line, both supplied at 25 feet in length. The suction line is insulated to prevent condensation and maintain system efficiency. Plain ends allow technicians to flare or braze connections in the field. A pre-formed 90-degree bend is included to simplify routing at the unit. Licensed HVAC technicians are the intended installers for this type of refrigerant-side component.

This lineset is suited for residential and light commercial split-system installations where the indoor and outdoor units are within 25 feet of each other. The 3/8 inch by 7/8 inch line sizes correspond to common mid-range cooling capacity systems. The copper construction handles standard refrigerants used in modern split systems. The pre-formed 90-degree bend reduces the need for field bending and helps protect line integrity at tight corners near equipment cabinets or wall penetrations.

Key Features

• 25-foot length suits typical residential split-system runs
• 3/8 inch OD liquid line and 7/8 inch OD suction line sizing for common mid-capacity systems
• Suction line insulation controls condensation and reduces heat gain
• Plain ends allow field flaring or brazing to match site requirements
• Pre-formed 90-degree bend simplifies routing near equipment
• Copper construction compatible with standard refrigerants used in split systems

Compatibility

Designed as an OEM-style replacement or new-installation lineset for split-system air conditioners and heat pumps requiring 3/8 inch liquid and 7/8 inch suction line connections at a 25-foot run length.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification for refrigerant handling. Shut down and de-energize the entire system before making any refrigerant-side connections. Field connections are typically made by flaring or nitrogen-purged brazing in accordance with local mechanical codes and manufacturer guidelines. Avoid kinking the lines during routing, and support the lineset at regular intervals to prevent sagging or vibration damage over time.
