Cambridge-lee Industries 061206200R Copper Line Set 20 Ft

Product Description

The CAMBRIDGE-LEE INDUSTRIES 061206200R is a pre-insulated copper refrigerant line set designed for residential and light commercial split-system HVAC installations. The set consists of a 3/8-inch liquid line and a 3/4-inch suction line, both running 20 feet in length. Suction line insulation is 3/8 inch thick and is rated UV resistant, making it suitable for exposed outdoor runs. The copper tubing meets ASTM B743/B88 material specifications and carries R-410A refrigerant approval. Plain end connections on both lines allow field technicians to cut and flare or braze to existing fittings without adapters. Licensed HVAC technicians are the primary installers of this product.

This line set is used in split-system air conditioning and heat pump installations where the indoor air handler or evaporator coil must be connected to an outdoor condensing unit. It is suited for residential new construction, system replacements, and retrofits where a 20-foot run covers the required distance between the two units. The plain end terminations provide flexibility for installers who prefer to make custom flare or brazed connections on-site. UV-resistant insulation helps maintain long-term performance on exposed exterior walls or rooftop runs where sunlight degradation is a concern.

Compatibility

Designed as an OEM-style replacement or new-install line set for residential and light commercial split-system air conditioners and heat pumps using R-410A refrigerant with a 3/8-inch liquid line and 3/4-inch suction line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable local mechanical codes and manufacturer system requirements. Disconnect and lock out power to both the indoor and outdoor units before making any line set connections. When brazing copper connections, use nitrogen purge to prevent oxidation scale inside the tubing. Insulation joints and field-cut ends should be sealed and taped to maintain the UV-resistant and thermal performance of the completed installation.
