Buying Guide

Match OD/ID to your fittings

Choose tubing with the exact outer or inner diameter specified by your fittings to avoid leaks or adapter needs

Check wall thickness and spec

Thicker walls (specified in inches or mm) and TP2/C12200 alloy listings indicate higher pressure tolerance and HVAC suitability

Decide between soft coil and straight lengths

Soft coils are easier for retrofit runs and bending, while straight lengths suit precision installations and flaring

Consider length vs. job waste

Longer coils reduce joints for long runs but increase handling; pick a length that minimizes cuts and fittings for your project

Verify seamless construction

Seamless tubing reduces leak risk at bends and fittings versus welded tubing, important for refrigeration and HVAC
