Jmf Company 061412500K Insulated Line Set 50 Ft

Product Description

The JMF COMPANY 061412500K is a pre-insulated refrigerant line set designed for standard residential and light-commercial split-system air conditioning and heat pump installations. The set includes a 3/8-inch liquid line and a 7/8-inch suction line, both wrapped in elastomeric rubber insulation at 3/4-inch thickness to minimize heat gain and condensation on the suction side. Total line length is 50 feet, making it suitable for mid-range equipment setups where the indoor and outdoor units require a longer run. Licensed HVAC technicians are the typical installers for this component.

This line set fits the conventional split-system configuration found in most residential cooling and heat pump applications. It is intended for use where the refrigerant circuit requires a matched pair of copper lines connecting the indoor evaporator coil to the outdoor condensing unit. The 50-foot length accommodates installations where the equipment cannot be located in close proximity, such as rooftop or side-yard placements with longer routing paths through walls or ceilings.

Key Features

• Elastomeric rubber insulation reduces heat transfer and prevents condensation on the suction line
• 3/4-inch insulation thickness meets standard requirements for conventional split-system line sets
• 3/8-inch liquid line and 7/8-inch suction line sized for common residential split-system equipment
• 50-foot length supports longer installation runs without field-splicing
• Conventional series design compatible with standard split-system configurations

Compatibility

Designed as an OEM-style replacement or new-installation line set for standard split-system air conditioning and heat pump equipment requiring a 3/8-inch liquid line and 7/8-inch suction line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes and refrigerant handling regulations. Shut down and recover all refrigerant from the system before disconnecting existing lines. Support the line set at regular intervals to prevent sagging and protect the insulation from abrasion at penetration points. Seal all wall and floor penetrations per local building code requirements after routing.
