Jmf Company 061208500k Copper Lineset 50 Ft Retrofit

Product Description

The JMF COMPANY 061208500k is a pre-insulated copper lineset designed for refrigerant line connections between an outdoor condensing unit and an indoor evaporator coil. The set includes a 3/8 inch liquid line and a 3/4 inch suction line, with 1/2 inch insulation applied to the suction line to minimize heat gain and condensation. At 50 feet in total length, this lineset is well-suited for residential split-system installations where the air handler or coil is located a meaningful distance from the outdoor unit. HVAC technicians use linesets like this one during new system installations and retrofit applications where existing copper lines must be replaced.

This lineset is part of the Retrofit series, making it appropriate for replacement scenarios on existing residential and light-commercial split-system air conditioning and heat pump installations. The 50-foot length provides flexibility for routing through walls, attics, and utility chases without the need for field fabrication of custom-length lines. The 3/8 inch liquid and 3/4 inch suction line sizing is common across a wide range of split-system tonnage configurations used in residential service work.

Key Features

• 3/8 inch liquid line and 3/4 inch suction line copper construction
• 1/2 inch insulation thickness on suction line reduces heat gain and controls condensation
• 50-foot length accommodates longer runs in residential retrofit applications
• Retrofit series designation suited for replacement of existing lineset installations
• Pre-insulated design reduces field labor during installation

Compatibility

Designed as an OEM-style replacement lineset for residential and light-commercial split-system air conditioners and heat pumps requiring a 3/8 inch liquid line and a 3/4 inch suction line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical codes and EPA Section 608 refrigerant handling regulations. Disconnect and recover refrigerant from the existing system before removing or connecting any refrigerant lines. Support the lineset at regular intervals per manufacturer and local code requirements to prevent sagging or vibration stress at fittings. Braze all connections using proper techniques and leak-test the completed assembly before recharging the system.
