The SIOUX CHIEF 623-L06 is a Type L copper stub out fitting used in residential and light commercial plumbing rough-in applications. Stub outs provide a short, fixed-length copper extension that terminates at the wall or floor surface, giving plumbers a clean, secure connection point for supply lines to fixtures such as sinks, toilets, and washing machines. Type L copper indicates medium-wall thickness, which meets standard residential water supply service requirements. The 3/4-inch diameter and 6-inch length make this stub out suited for branch supply lines where a compact, rigid protrusion is needed before final fixture trim-out.
This stub out is used during the rough-in phase of new construction and remodel plumbing work. It is installed behind the finished wall or floor surface and capped until the fixture connection is made at trim-out. The 3/4-inch size is common on main branch lines feeding individual fixtures or appliance supplies. Licensed plumbers and plumbing contractors handle installation as part of the rough-in stage prior to drywall or finish flooring.
Designed as an OEM-style rough-in component for residential and light commercial copper water supply systems using standard 3/4-inch Type L copper fittings and connections.
Installation is performed by a licensed plumber during the rough-in phase of construction. Shut off the water supply and depressurize the line before soldering or pressing any connections. Work must comply with applicable local plumbing codes and the International Plumbing Code (IPC). Cap the stub out after rough-in inspection and do not leave open lines unprotected before trim-out.
