1/2 inch Galvanized Steel Nipple Run (Close to 6 inch)

1/2" Galvanized Steel Nipple – Schedule 40, Threaded Both Ends

The 1/2" Galvanized Steel Nipple is a Schedule 40 pipe segment with male NPT threads on both ends, manufactured for use in threaded steel piping systems. Constructed from carbon steel and hot-dip galvanized in accordance with ASTM A153, this nipple provides extended corrosion protection in above-ground plumbing, mechanical, and low-pressure gas installations.

Threaded per ANSI/ASME B1.20.1, this fitting is intended for joining compatible pipe or fittings in structural or fluid systems where durability, mechanical strength, and dimensional consistency are critical. It is suitable for indoor, dry, or moderately corrosive environments where a zinc-coated surface enhances resistance to oxidation.

Technical Specifications

• Nominal Pipe Size: 1/2 inch
• Length Range: Typically available in close, 2", 4", 6", and up to 72" lengths
• Wall Thickness: Schedule 40
• Material: Carbon steel (ASTM A53), hot-dip galvanized finish

Installation Considerations

Install using appropriate pipe wrenches and apply PTFE thread sealant or approved pipe joint compound to ensure leak-tight connections. Avoid overtightening, which may damage threads or stress mating components. Not rated for potable water use unless approved for such by local code and labeling. Do not install in underground or high-chloride environments without supplemental coating or protection.

Typical Applications

Commonly used in structural support systems, water distribution (non-potable), compressed air lines, and fuel gas piping where rigid, threaded steel connections are required. The galvanized finish supports use in utility spaces, service corridors, and other dry environments subject to atmospheric moisture.

Field Use Insight

Galvanized steel nipples provide a rigid, corrosion-resistant option for extending or connecting pipe runs. They are frequently specified in fire protection system hangers (dry zones), rooftop HVAC pipe supports, and mechanical installations where strength and long service life are critical.

Threaded Galvanized Nipple for Durable, Code-Compliant Connections

The 1/2" Galvanized Steel Nipple delivers consistent dimensional quality and corrosion resistance in mechanical and plumbing systems. Suitable for commercial and industrial use, it offers a standardized solution for rigid, threaded piping applications in accordance with recognized codes and installation practices.
