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

1/2" x 4-1/2" Galvanized Steel Nipple – Threaded Connector for Corrosion-Resistant Pipe Assemblies

The 1/2" x 4-1/2" Galvanized Steel Nipple is manufactured from welded schedule 40 steel pipe and hot-dip galvanized for corrosion resistance in non-potable fluid and air applications. With male NPT threads on both ends, it provides a secure, tapered-thread connection between system components in pressurized or atmospheric service lines.

Fabricated in accordance with ASTM A53 and A733, this fitting is intended for use in water distribution, HVAC, compressed air, and low-pressure gas systems. The hot-dip galvanized coating protects against moisture and environmental exposure, making it well-suited for indoor and outdoor installation environments.

Key Product Attributes

• Hot-Dip Galvanized Coating – Zinc coating applied per ASTM A153 provides long-term corrosion protection in damp and exposed service conditions.
• Threading Standard – National Pipe Taper (NPT) threads machined to ANSI B1.20.1 for reliable sealing with compatible female-threaded components.
• Schedule 40 Wall – Ensures strength and structural integrity in general-purpose applications, including mechanical and plumbing systems.
• Exact Length – Overall length of 4-1/2" provides flexible spacing for installations requiring intermediate pipe sections or coupling extensions.
• Material Compliance – Carbon steel construction per ASTM A53 for durability under mechanical and thermal loading.

Installation Considerations

Install using standard wrenches and apply a compatible thread sealant or PTFE tape rated for system contents (e.g., water, air, or gas). Avoid excessive torque to preserve thread integrity and prevent misalignment. Verify system pressure ratings and perform leak testing prior to commissioning. Always adhere to applicable IPC, UPC, or local code requirements when working with galvanized components in potable and non-potable systems.

Typical Applications

Commonly used in plumbing, mechanical, and HVAC systems for connecting fittings, valves, and sections of pipe. Suitable for use in maintenance operations, pipe supports, pump connections, and process installations in residential, commercial, and industrial projects.

Material Note

Galvanized steel is selected for applications requiring extended resistance to rust and corrosion without sacrificing mechanical strength, especially in environments subject to condensation, ambient humidity, or outdoor exposure.
