Buying Guide

Confirm tube dimensions

Match outer diameter, inner diameter, and wall thickness to your fittings and system to avoid leaks or adapter needs

Choose the right temper

Soft (annealed) tubing bends easily for coils and tight runs, while harder tempers are better for flaring and rigid installs

Check alloy/spec

Look for UNS C12200/TP2 or equivalent specs for common HVAC and refrigeration compatibility and brazing performance

Pick length to minimize joints

Longer coils reduce joints and leak points, but are heavier to handle and may require more storage space

Consider application-specific size

Common sizes like 1/4", 3/8", 1/2", 5/8", and 3/4" OD align with typical refrigeration and HVAC fittings—confirm system requirements first
