The Lead-Free 1 Red Bronze Cross is a lead-free (LF) red bronze (RB) cross fitting used in piping systems. It features four openings, with all ports having the same nominal size. This type of fitting is typically used to connect multiple pipe runs in T-shaped or cross-shaped configurations, allowing the direction of flow to be split or combined between different pipelines. The lead-free red bronze material ensures the fitting is safe for potable water systems while offering strong resistance to corrosion, making it durable in various applications.
