Jmf Company 618 3/8X11/8X1/2H Ez Pull Line Set 50 Ft

Product Description

The JMF COMPANY 618 3/8X11/8X1/2H is a pre-insulated refrigerant line set designed for split-system air conditioning and heat pump installations. The set includes a 3/8-inch liquid line and a 1-1/8-inch suction line, both run at 50 feet in length and wrapped with 1/2-inch wall insulation. The EZ Pull design allows a single installer to feed both lines simultaneously, reducing labor time on standard residential and light-commercial installs. HVAC technicians use this line set to connect an outdoor condensing unit to an indoor air handler or evaporator coil.

This line set is suited for residential split-system cooling and heat pump applications where the indoor and outdoor units are separated by up to 50 feet of run. The 3/8-inch liquid line and 1-1/8-inch suction line sizing targets larger-capacity systems commonly found in residential new construction and retrofit work. The 1/2-inch insulation on the suction line limits heat gain and condensation along the refrigerant circuit.

Key Features

• 50-foot total run length suits most residential and light-commercial installations
• 3/8-inch liquid line and 1-1/8-inch suction line for larger-capacity split systems
• 1/2-inch wall insulation reduces heat gain and controls condensation on the suction line
• EZ Pull configuration bundles both lines for single-person routing through walls and chases

Compatibility

Designed as an OEM-style replacement or new-installation line set for residential and light-commercial split-system air conditioners and heat pumps requiring a 3/8-inch liquid line and a 1-1/8-inch suction line.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification, as this work involves a sealed refrigerant system. Recover any existing refrigerant before disconnecting old line sets and isolate power to both the indoor and outdoor units before beginning work. Protect line set ends from contamination and moisture during the pull-through process, and braze or flare connections per the equipment manufacturer's instructions and local mechanical code requirements. Avoid sharp bends that could kink the copper tubing.
