Buying Guide

Match OD/ID to your fittings

Confirm outer and inner diameters (e.g., 3/4" OD, 7/16" ID) to ensure proper fit with flare nuts, compression fittings, or sweat joints

Choose soft vs. hard copper by application

Soft (annealed) copper coils bend easily for refrigeration lines and tight routing; hard (drawn) tube is better for straight runs and structural support

Check length and coil format

Select convenient lengths (5–25 ft common in this set) and soft-coil packaging for easier handling versus rigid cut lengths for precise installations

Prefer seamless for pressure applications

Seamless tubing reduces leak risk under pressure, making it preferable for HVAC and refrigeration lines where consistent wall integrity matters

Consider common HVAC sizes

Typical sizes like 1/4", 1/2", 5/8", and 3/4" OD are included here; pick the size matching your system to avoid adapters or extra fittings
