Cambridge-lee Industries 061412300B Line Set 30 Feet

Product Description

The CAMBRIDGE-LEE INDUSTRIES 061412300B is a pre-insulated copper refrigerant line set designed for split-system and ductless mini-split installations. It includes a 3/8-inch liquid line and a 7/8-inch suction line, both enclosed in 3/4-inch black polyethylene hard-shell insulation. The set measures 30 feet in length and ships with plain ends on both sides, ready for field flaring or brazing. Copper tubing meets ASTM B743 and B88 material standards. The exterior insulation is UV-resistant and rated for R-410A refrigerant systems. HVAC technicians use this line set to connect indoor and outdoor units during new installations or equipment changeouts.

This line set is suited for residential and light commercial applications including ductless mini-split systems, VRF commercial systems, and conventional split-system air conditioners and heat pumps. The rugged anti-tear exterior shell is engineered to resist damage during pull-through installations in walls, ceilings, or conduit runs. Insulation is marked every foot to simplify measurement and layout on the job. It is appropriate for both new construction and retrofit scenarios where pre-insulated line sets reduce field labor.

Key Features

• 3/8-inch liquid line and 7/8-inch suction line in a single pre-insulated assembly
• 3/4-inch black polyethylene hard-shell insulation rated for R-410A systems
• UV-resistant exterior suitable for exposed or partially exposed runs
• Anti-tear outer shell designed for easier pull-through installation
• Insulation marked every foot for accurate field measurement
• Plain end x plain end connection for field flaring or brazing

Compatibility

Designed for use with ductless mini-split systems, VRF commercial systems, and split-system air conditioners and heat pumps using R-410A refrigerant.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with EPA Section 608 refrigerant handling requirements. Disconnect and lock out power to both indoor and outdoor units before making any refrigerant line connections. Plain ends require field flaring or silver-alloy brazing with nitrogen purge to meet industry standards. Secure and support the line set at regular intervals per local mechanical code requirements to prevent vibration stress on connections.
