Cambridge 223468 Insulated Lineset 3/8 X 5/8 X 50 Ft Ez Pull

Product Description

The CAMBRIDGE 223468 is a pre-insulated refrigerant lineset designed for split-system air conditioning and heat pump installations. The lineset consists of two copper lines — a 0.375-inch suction line and a 0.625-inch liquid line — run together at 50 feet in length and wrapped with 0.5-inch EZ Pull insulation. The EZ Pull construction allows technicians to route the lineset through walls, chases, and conduit with significantly less friction and resistance than standard linesets. Licensed HVAC technicians handling residential and light commercial split-system installations are the primary installers of this product.

This lineset is suited for residential and light commercial split-system HVAC applications where the air handler or evaporator coil is located indoors and the condensing unit is mounted outside. The 50-foot run length accommodates most standard installations where the indoor and outdoor units are separated by one or two stories or moderate horizontal distance. The 0.5-inch insulation wall helps limit heat gain on the suction line, supporting system efficiency. This product is also cross-referenced under part numbers LSB385850EZ, ARMASHIELD 610K0500L, and TITAN A385812050BLK.

Key Features

• EZ Pull insulation jacket reduces installation friction when pulling through walls and conduit
• 0.375-inch suction line and 0.625-inch liquid line paired in a single 50-foot assembly
• 0.5-inch insulation wall limits heat transfer on the suction line
• Cross-compatible with ARMASHIELD 610K0500L and TITAN A385812050BLK references
• 50-foot length covers most residential split-system line runs without field splicing

Compatibility

Cross-referenced as a direct replacement for LSB385850EZ, ARMASHIELD 610K0500L, and TITAN A385812050BLK. Designed for use in residential and light commercial split-system air conditioning and heat pump installations requiring a 0.375-inch by 0.625-inch lineset configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes and the equipment manufacturer's instructions. Shut down and recover all refrigerant from the existing system before disconnecting any line connections. Ensure the lineset is properly supported, protected from physical damage, and sealed at all wall penetrations per local building code requirements. Do not kink or sharply bend the copper lines during routing, as deformation can restrict refrigerant flow and damage the system.
