Jmf Company 061212250K Copper Ac Lineset 3/8x3/4 25 Ft

Product Description

The JMF COMPANY 061212250K is a pre-insulated copper refrigerant lineset designed for split-system air conditioning and heat pump installations. It consists of a 3/8 inch liquid line and a 3/4 inch suction line, spanning 25 feet in total length. The suction line features 3/4 inch insulation thickness to minimize heat gain and maintain system efficiency. This Conventional Series lineset is a standard trade-grade component installed by licensed HVAC technicians connecting indoor air handlers or evaporator coils to outdoor condensing units.

This lineset is suited for residential and light commercial split-system HVAC applications where a 3/8 inch liquid line and 3/4 inch suction line are specified. The 25-foot length covers typical installations where the indoor and outdoor units are in close proximity, such as single-story residential homes or ground-level commercial equipment pads. It is part of the Conventional Series, making it appropriate for standard refrigerant systems requiring pre-sized, pre-insulated line sets.

Key Features

• Copper construction for reliable refrigerant flow and long service life
• 3/8 inch liquid line and 3/4 inch suction line in a single pre-paired set
• 25-foot length suitable for typical residential split-system runs
• 3/4 inch insulation thickness on suction line reduces heat gain and condensation
• Conventional Series design for compatibility with standard split-system configurations

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 liquid line and 3/4 inch suction line.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes and EPA Section 608 refrigerant handling regulations. Power down the condensing unit and air handler before making any line connections. Avoid kinking or sharp bends in the copper tubing during routing, as restrictions will negatively affect system performance. Braze or flare connections per manufacturer specifications and pressure-test the completed line set before evacuating and charging the system.
