Boshart NIPGL86 NIPGL Series Galvanized Steel Close Pipe Nipple, 3" - 4"

Boshart NIPGL Series Galvanized Steel Close Pipe Nipple

The Boshart NIPGL Series close pipe nipple is a galvanized steel threaded connector built for rough-in plumbing and mechanical piping runs where a short connector is needed between two fittings or a fitting and a valve. This family is available in 3" and 4" nominal pipe sizes, giving contractors a larger-diameter option for mechanical rooms, utility piping, and equipment connections. Manufactured from galvanized steel for corrosion resistance in exposed and utility piping applications, every size in the NIPGL Series is threaded on both ends to join directly with standard IPS-threaded fittings, valves, and equipment connections. As a close nipple, the design has no unthreaded shoulder between the two thread runs, allowing fittings to be joined back-to-back in tight spaces where a standard-length nipple will not fit. Plumbers and contractors rely on close nipples like this one for compact transitions in mechanical rooms, water heater connections, pump and equipment hookups, and any application where two threaded fittings need to be joined directly with minimal added length.

Key Features

• Trade Size Range: Available in 3" and 4" nominal pipe size for larger-diameter mechanical and rough-in piping runs.
• Close Nipple Configuration: No unthreaded shoulder between thread runs, letting two fittings be joined directly for the shortest possible connection length.
• Durable Construction: Galvanized steel construction resists corrosion in exposed, damp, or utility piping environments.
• Threaded Connection: Male threaded on both ends for direct mating with standard IPS-threaded fittings, valves, and equipment ports.
• NIPGL Series: Part of Boshart's NIPGL galvanized nipple series, sized and threaded for compatibility with standard galvanized and black iron fitting systems.
• Compact Design: Ideal for tight-clearance installations where a full-length nipple would not fit between adjoining fittings.
