1 inch x 48 inch Galvanized Steel Nipple

1" x 48" Galvanized Steel Nipple – Threaded Fitting for Pressure-Grade Systems

The 1" x 48" Galvanized Steel Nipple is manufactured for use in water, air, oil, and steam systems requiring high tensile strength and corrosion resistance. Threaded ends ensure a tight, leak-resistant seal suitable for joining pipe sections, valves, or equipment in both supply and drainage systems.

Constructed from schedule 40 carbon steel and hot-dip galvanized to ASTM A153 standards, this fitting provides added protection in corrosive or humid environments. The extended 48" length accommodates long-run assemblies where flexibility and distance are required without adding multiple short nipples and couplings.

Performance and Product Features

• ✅ Hot-Dip Galvanized Finish Provides a zinc coating for corrosion protection in water and non-aggressive service lines.
• ✅ Schedule 40 Wall Thickness Suitable for medium-pressure systems and compliant with ASTM A733 dimensional standards.
• ✅ NPT Threads Machined to ANSI B1.20.1 specifications for precise fit and consistent sealing integrity.
• ✅ 48-Inch Length Reduces the need for couplings in extended horizontal or vertical runs, minimizing joint potential failure points.
• ✅ Versatile Application Used in commercial and residential plumbing systems, including water distribution, fire protection, and mechanical piping layouts.

Technical Specifications

• Material: Carbon steel, hot-dip galvanized
• Size: 1" nominal diameter x 48" length
• Thread Type: NPT male x NPT male
• Compliance: Meets ASTM A733, A53, and ANSI/ASME B1.20.1 standards

Installation Considerations

For best results, use with compatible NPT-threaded components. Apply an appropriate thread sealant or PTFE tape to prevent galling and ensure watertight performance. Torque fittings with calibrated pipe wrenches to avoid over-tightening, which may compromise thread integrity or cause stress cracking in fittings or joints.

Typical Applications

This galvanized nipple is commonly deployed in industrial and commercial water supply systems, mechanical piping, HVAC loops, and general-purpose compressed air or hydraulic systems. It is suitable for above-ground installations and applications that benefit from corrosion-resistant steel.

Note on Material Suitability

Galvanized steel pipe and fittings are not recommended for use in potable water systems containing soft water or aggressive pH ranges, which can degrade the protective zinc layer over time.

Engineered to provide consistent performance and compliance with pressure-rated system designs, the 1" x 48" Galvanized Steel Nipple is an essential component in professional-grade installations where long service life and system integrity are required.
