Potter Roemer 5941 Pin Lug Plug with Chain 2-1/2 Nst

Product Description

The POTTER ROEMER 5941 is a pin lug plug with attached chain sized for 2-1/2 inch National Standard Thread (NST) fire protection hose connections. This plug is used to cap and protect female hose outlets when not in active use, keeping threads clean and free from debris or physical damage. The attached chain secures the plug to the outlet fitting so it stays in place and is not misplaced during service. Licensed fire protection contractors and facility maintenance professionals install this hardware as part of routine fire system upkeep and inspections.

The 5941 is designed for use on fire department connections, standpipe outlets, and hose valve outlets where a 2-1/2 inch NST thread is present. This size is standard across a wide range of wet and dry standpipe systems in commercial, industrial, and institutional buildings. It is a common replacement item during fire system inspections, hose valve servicing, and outlet refurbishment work.

Installation Notes

Installation and removal of fire protection fittings should be performed by a licensed fire protection contractor in compliance with NFPA 13, NFPA 14, and local authority having jurisdiction (AHJ) requirements. Isolate and depressurize the affected portion of the system before removing or installing any threaded plug. Inspect threads on both the plug and the outlet for damage before seating the plug. Do not over-tighten; use only the pin lug ears for tool engagement.
