Cambridge 223390 Insulated Lineset 3/8 X 3/4 in 25 Ft Ez Pull

Product Description

The CAMBRIDGE 223390 is a pre-insulated refrigerant lineset designed for split-system air conditioning and heat pump installations. The EZ Pull design simplifies routing through walls, ceilings, and conduit runs, reducing installation time on residential and light commercial jobs. This lineset ships as a matched pair of copper lines — a 3/8-inch suction line and a 3/4-inch liquid line — each wrapped with foam insulation and bundled together for a clean, single-pull run. At 25 feet in length, it covers most standard residential setups. HVAC technicians working split-system installs will recognize the ARMASHIELD-compatible construction and the cross-reference to TITAN A383412025BLK and ARMASHIELD 612K0250L.

This lineset is suited for residential split-system AC and heat pump installations where the air handler and outdoor condensing unit are within 25 feet of each other. The EZ Pull bundle format is especially useful in new construction and retrofit applications where the lineset must be fished through framed walls or pulled through a single conduit sleeve. The 3/8-inch by 3/4-inch line pair sizing is a common configuration for mid-range residential cooling equipment.

Compatibility

Cross-references ARMASHIELD 612K0250L and TITAN A383412025BLK. The 3/8-inch by 3/4-inch line sizing is compatible with many residential split-system air conditioners and heat pumps that call for this standard line pair configuration. Confirm equipment manufacturer line size requirements before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 refrigerant handling certification. Always recover any remaining system refrigerant and isolate the system before disconnecting existing lines. Support the lineset at manufacturer-recommended intervals to prevent sagging and vibration contact with structural members. Braze or flare connections per the equipment manufacturer's specifications and pressure-test before recharging.
