Boshart SS304N55 304 Stainless Steel Threaded Close Nipple

Boshart SS304N55 304 Stainless Steel Threaded Close Nipple

The Boshart SS304N55 close nipple is built from welded 304 stainless steel pipe for threaded rough-in connections that demand corrosion resistance, and this listing covers the full close nipple family, available in sizes ranging from 1/4" up to 1-1/2". A close nipple joins two female threaded fittings with minimal exposed thread between the connection points, making it the right choice for tight-clearance stainless steel assemblies in mechanical rooms, pump stations, wash-down areas, and other applications where a compact threaded joint is required. As a 304-grade stainless steel component, it holds up well against moisture and many corrosive environments compared to standard carbon steel nipples, giving contractors and plumbers a durable option for stainless threaded piping systems across the size range.

Key Features

• Trade Size Range: Available from 1/4" up to 1-1/2" close nipple sizes, each sized for a direct threaded connection between two fittings with no exposed pipe run.
• Durable Construction: Made of 304 stainless steel welded pipe for corrosion resistance and long service life versus standard steel nipples, across every size in the family.
• Threaded Connection: Threaded on both ends for joining directly into female-threaded stainless steel fittings, valves, or equipment ports.
• Close-Coupled Design: The close nipple length places two connections back-to-back on every size, ideal where space between fittings is limited.
• Recommended Sealant: Boshart recommends using Gray Stainless Steel PTFE Tape together with Gray Magic Pipe Thread Compound when joining this and other stainless steel threaded fittings for a proper seal.
• Bulk Packaging: Packaged 25 pieces per unit, suited for stocking trucks or supply houses that install stainless steel threaded nipples regularly.

Why Boshart?

Boshart builds this close nipple family from 304 stainless steel welded pipe, a material choice suited to threaded connections that need to resist corrosion better than standard steel, whether you need the smallest 1/4" size or the largest 1-1/2" size in the range. Boshart's own installation guidance - pairing Gray Stainless Steel PTFE Tape with Gray Magic Pipe Thread Compound - reflects attention to how these fittings actually get installed in the field, helping contractors achieve a reliable seal on stainless threaded joints regardless of size. For plumbers and contractors standardizing on stainless steel rough-in components, the SS304N55 close nipple family is a straightforward, code-relevant building block for threaded assemblies, and the 25-piece bulk packaging makes it practical for supply houses and trucks that stock multiple sizes for daily rough-in work.
