Jmf Company dl06101225kx Mini Split Lineset 25 Ft

Product Description

The JMF COMPANY dl06101225kx is a double-insulated copper lineset designed for mini split air conditioning and heat pump systems. It consists of two refrigerant lines — a 3/8-inch liquid line and a 5/8-inch suction line — pre-insulated and packaged at 25 feet in length. The double-insulation construction on the suction line reduces condensation and heat gain, which is critical for maintaining system efficiency. HVAC technicians install this lineset to connect the indoor air handler to the outdoor condensing unit during new mini split installations or system replacements.

This lineset is suited for residential and light commercial mini split installations where a 25-foot run is sufficient to bridge the indoor and outdoor units. The 3/8-inch liquid line and 5/8-inch suction line sizing is a common configuration for single-zone mini split systems in the 9,000 to 24,000 BTU/h range. It is appropriate for both wall-mounted and ceiling cassette indoor unit installations where refrigerant line routing is required.

Key Features

• Double-insulated construction minimizes condensation and heat transfer on the suction line
• 3/8-inch liquid line and 5/8-inch suction line for standard mini split sizing
• 25-foot length covers typical residential installation runs
• Copper construction for reliable refrigerant containment and long service life
• Pre-paired lines simplify routing and reduce installation time

Compatibility

Designed as an OEM-style replacement or new-installation lineset for mini split systems requiring a 3/8-inch liquid line and 5/8-inch suction line configuration.

Installation Notes

Installation should be performed by an EPA Section 608 certified HVAC technician. Before connecting the lineset, recover any refrigerant from an existing system and de-energize all equipment. Avoid kinking the copper tubing during routing; use a tubing bender where directional changes are needed. Pressure-test and leak-check the completed lineset connections before evacuating and charging the system.
