1/2 inch x 6 inch Galvanized Steel Nipple

1/2" x 6" Galvanized Steel Pipe Nipple – Schedule 40, NPT Threaded

The 1/2" x 6" Galvanized Steel Nipple is a Schedule 40 carbon steel fitting used for joining two threaded pipe sections in non-corrosive and low- to moderate-pressure systems. It is fabricated from welded or seamless steel pipe per ASTM A53 standards and hot-dip galvanized in accordance with ASTM A123 for enhanced corrosion resistance in indoor or dry service environments.

Both ends are machined with National Pipe Thread Taper (NPT) per ANSI/ASME B1.20.1, ensuring compatibility with standard threaded steel pipe and fittings. This nipple provides a rigid extension and is typically used in heating loops, compressed air lines, and water distribution systems where galvanized protection is appropriate.

Product Specifications

• Material: Carbon steel, hot-dip galvanized
• Nominal Pipe Size: 1/2 inch
• Overall Length: 6 inches
• Wall Thickness: Schedule 40
• Connection: NPT male threads on both ends (tapered per ANSI B1.20.1)
• Standards: Conforms to ASTM A53 (pipe body), ASTM A123 (zinc coating)

Installation Guidelines

Use PTFE tape or approved thread sealant to achieve leak-resistant joints. Thread engagement should be verified manually, and fittings must not be over-tightened to avoid thread deformation. For pressurized systems, ensure pressure testing is conducted in accordance with code and manufacturer guidelines. Pipe and fittings should be properly supported to reduce mechanical strain on threaded connections.

Common Applications

Suitable for use in non-potable water lines, mechanical heating systems, air distribution, and other low-pressure piping systems. It is often used in hydronic installations, pipe supports, pump connections, and system extensions where galvanized components are specified or permitted by code.

Material Limitations

Not recommended for use in potable water systems unless explicitly approved for lead-free compliance. Galvanized steel should not be used in underground or corrosive environments unless additional coatings or corrosion protection measures are applied. For aggressive fluids or higher corrosion resistance, consider stainless or plastic alternatives.

The 1/2" x 6" Galvanized Steel Nipple provides a durable, code-compliant solution for contractors requiring a rigid, threaded pipe segment in galvanized piping assemblies.
