1/4″ × 3/8″ Lineset

1/4″ × 3/8″ Pre-Insulated Lineset — Calgary

A common size for smaller residential systems and light-duty changeouts. This is a pre-insulated twin copper coil — 25 ft with 1/2-inch insulation on both lines, so there’s no field insulating to do. Uncoil it, run it, braze it, and move on to the next job.

Sizing note: line sizing must match the equipment — check the equipment nameplate and the manufacturer’s installation manual. Send us your model number and we’ll help you match the right size.
