Buying Guide

Choose the right alloy

Select stainless (304/316L) for corrosion resistance in sanitary or marine settings, brass for machinability and decorative use, and carbon/A513 steel for structural strength

Match diameter and wall thickness

Confirm outer/inner diameters and wall gauge to meet flow, pressure, and load requirements; small changes in wall thickness greatly affect strength and weight

Pick the proper connection style

Use tri-clamp/ferrule fittings for sanitary and food-grade systems and welded or plain-end tubing for structural or custom-joined assemblies

Consider length and handling

Standard stocked lengths (3–4 ft) simplify cutting and minimizing waste, but longer runs or multiple pieces may require special handling or shipping

Check finish and tolerances

Polished or electropolished finishes improve cleanability for sanitary tubing, while drawn or cold-roll tubing offers tighter dimensional tolerances for precision work
