Cambridge 223391 Ez Pull Insulation Lineset 3/8 X 3/4 in 30 Ft

Product Description

The CAMBRIDGE 223391 is an EZ Pull insulation lineset designed for mini-split and ductless HVAC system installations. This pre-insulated lineset pairs a 3/8-inch suction line with a 3/4-inch liquid line in a 30-foot run, simplifying the refrigerant line routing process between indoor air handlers and outdoor condensing units. The EZ Pull construction allows the two lines to be separated easily without cutting insulation, saving labor time on the job. HVAC technicians installing ductless systems rely on this type of lineset for clean, code-compliant refrigerant line runs in both residential and light commercial applications.

This lineset is suited for residential and light commercial ductless mini-split installations where a 30-foot line run is needed between the indoor and outdoor units. The 3/8-inch by 3/4-inch line size accommodates common mini-split system configurations. The EZ Pull design is especially useful in retrofit installations or where routing through walls, ceilings, or conduit requires separating the two lines at different points along the run. Compatible part references include LSB383430EZ, ARMASHIELD 612K0300L, and TITAN A383412030BLK.

Compatibility

Cross-references to LSB383430EZ, ARMASHIELD 612K0300L, and TITAN A383412030BLK. Designed as an OEM-style replacement or new-install lineset for mini-split and ductless HVAC systems requiring a 3/8 x 3/4 inch, 30-foot insulated refrigerant line configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification for refrigerant handling. Power down and lock out the outdoor condensing unit before connecting or disconnecting any refrigerant lines. Route lines carefully to avoid kinking, and follow local mechanical codes and manufacturer torque specifications for flare fittings. Do not braze or modify the lineset without verifying compatibility with the refrigerant type specified for the connected system.
