The 15.88mm Round Weld-On End Cap is a small but precise flat plate cap for permanently closing the open ends of 15.88mm round stainless steel infill tubing. Welded over the tube end by the installer, it creates a fully fused, solid termination with no inner stem or press-fit mechanism — appropriate for welded infill systems where every connection in the assembly is permanently joined.
At this diameter, consistent welding and finishing across all infill tube ends is a mark of a quality installation. This cap provides the correct starting point for that result.
Manufactured in Grade 316 Marine Grade stainless steel with a mirror polish finish.
