3/4 inch x 2-1/2 inch Galvanized Steel Nipple

3/4" x 2-1/2" Galvanized Steel Nipple – Threaded Pipe Connector for Pressure Systems

The 3/4" x 2-1/2" Galvanized Steel Nipple is designed for connecting lengths of pipe or fittings in threaded piping systems. Constructed from steel and coated with a layer of zinc via hot-dip galvanizing, this component provides enhanced corrosion resistance in water, air, and low-pressure gas systems. It is suitable for use in both residential and commercial mechanical installations.

Product Specifications

• Material: Carbon Steel with Hot-Dip Galvanized Finish
• Size: Nominal 3/4 inch diameter x 2-1/2 inch overall length
• Connection Type: Male National Pipe Thread (NPT) both ends
• Standards: Threads conform to ANSI/ASME B1.20.1; zinc coating complies with ASTM A153
• Application: For use in non-potable water lines, HVAC systems, low-pressure gas piping, and general fluid handling

Performance and Usage

This galvanized nipple offers structural durability and corrosion resistance for above-ground use in environments where moisture or humidity may be present. It is compatible with other malleable iron, steel, or galvanized fittings using tapered NPT threads. The component is pressure-rated in accordance with schedule 40 standards and is not intended for high-temperature steam or potable water without appropriate lining or treatment.

Installation Considerations

Installation requires the use of appropriate threading tools and sealing methods such as PTFE tape or thread compound. Tightening should be done with a pipe wrench, avoiding over-torque to preserve thread integrity. Always verify system compatibility and follow applicable local codes and safety standards.

Common Applications

• Water distribution systems (non-potable)
• Low-pressure natural gas and propane lines
• Hydronic heating loop components
• Air compressor lines and mechanical systems

Note:

Galvanized steel is widely used in industrial piping due to its ability to resist corrosion, especially in outdoor or damp indoor environments. However, it should not be used in systems carrying drinking water unless explicitly rated for that purpose.

The 3/4" x 2-1/2" Galvanized Steel Nipple provides a dependable threaded solution for a variety of mechanical piping scenarios. Its design supports clean installations and long-term system integrity across a wide range of applications.
