Jmf Company DL04061230KX Mini Split Lineset 1/4x3/8 30ft

Product Description

The JMF COMPANY DL04061230KX is a pre-cut copper lineset designed for mini split air conditioning and heat pump systems. It pairs a 1/4-inch liquid line with a 3/8-inch suction line, both wrapped in double-layer insulation rated at 3/4 inch thick. The 30-foot length suits most residential and light-commercial mini split installations where the indoor air handler and outdoor condenser are separated by a standard run. HVAC technicians install this lineset during new mini split system commissioning or when replacing damaged or undersized line sets.

This lineset is suited for ductless mini split applications including single-zone and select multi-zone systems that call for 1/4-inch by 3/8-inch line sizing. The double insulation construction reduces heat gain on the suction line and helps maintain system efficiency across the full 30-foot run. It fits typical wall-penetration installations where the lineset routes from an indoor wall-mount unit to an outdoor condensing unit on residential or light-commercial structures.

Key Features

• 1/4-inch liquid line and 3/8-inch suction line sized for standard mini split applications
• Double-insulated construction with 3/4-inch insulation thickness for improved thermal performance
• 30-foot pre-cut length ready for field installation without additional cutting or brazing of coil stock
• Copper construction for reliable refrigerant containment and long service life

Compatibility

Designed as an OEM-style replacement or new-installation lineset for ductless mini split systems requiring 1/4-inch liquid and 3/8-inch suction line connections.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification, as this work involves refrigerant handling. Power down the mini split system at the disconnect and at the breaker panel before making any line connections. Flare or braze connections according to the equipment manufacturer specifications and local mechanical code requirements. Secure the lineset along the run using appropriate line set hangers or tape to prevent vibration and physical damage.
