The ANDERSON METALS CORP 38300-0840 is a red brass pipe nipple sized at 0.5 inches by 4 inches, designed for use in residential and light commercial plumbing systems. Red brass offers higher lead-free copper content than standard yellow brass, making it well suited for potable water applications where corrosion resistance and material compliance matter. This nipple is lead free compliant and meets California AB-1953 and Vermont SB-152 legislation requirements. Licensed plumbers and pipefitters install this fitting when connecting threaded pipe runs, extending supply lines, or making up assemblies at fixtures, valves, and other threaded components.
This nipple is appropriate for use in potable water supply lines, hot and cold distribution systems, and general plumbing rough-in work. Its 0.5-inch thread size is one of the most common nominal pipe sizes found in residential fixture supply and branch line applications. The 4-inch length provides adequate clearance for close-quarters assembly work where standard close nipples would not give enough thread engagement room. Sold in bulk packs of 5 units per package.
Designed as an OEM-style replacement or new-installation fitting compatible with standard 0.5-inch NPT threaded pipe and fittings used in residential and commercial plumbing systems.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before making any threaded connections. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-tighten threaded connections, as red brass fittings can be damaged by excessive force.
