Jmf Company 061012500k Copper Lineset 3/8 X 5/8 50 Ft

Product Description

The JMF COMPANY 061012500k is a pre-insulated copper lineset designed for split-system HVAC applications. It consists of a 3/8-inch liquid line and a 5/8-inch suction line, both running 50 feet in length. The suction line insulation measures 3/4 inch thick, helping to minimize heat gain and prevent condensation along the refrigerant circuit. This lineset is part of the Conventional Series and is installed by licensed HVAC technicians connecting an outdoor condensing unit to an indoor air handler or evaporator coil. Copper construction ensures compatibility with common refrigerants and long-term durability in residential and light commercial systems.

This lineset is suited for residential and light commercial split-system air conditioning and heat pump installations where a 50-foot run is required. The 3/8-inch liquid line and 5/8-inch suction line sizing is a common pairing for mid-range cooling capacity systems. It is typically routed through walls, ceilings, or exterior line-set covers before being connected and pressure-tested at the service valves. The Conventional Series designation indicates standard construction without factory-flared or pre-charged fittings.

Key Features

• Copper construction for reliable refrigerant transport and long service life
• 50-foot length covers typical residential and light commercial installation runs
• 3/8-inch liquid line and 5/8-inch suction line sizing for common split-system applications
• 3/4-inch insulation thickness on the suction line reduces heat gain and condensation
• Conventional Series — compatible with standard field-flare and braze connection methods

Compatibility

Designed as an OEM-style replacement or new-installation lineset for residential and light commercial split-system air conditioners and heat pumps requiring 3/8-inch liquid and 5/8-inch suction line connections.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and manufacturer guidelines. Shut off and recover all refrigerant before disconnecting any existing lineset, and de-energize the system at the disconnect before beginning work. The lineset should be leak-tested with dry nitrogen before system charging, and all connections should be properly flared or brazed to prevent refrigerant loss. Avoid sharp bends that could restrict refrigerant flow or damage the copper tubing.
