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

1/2" x 2-1/2" Galvanized Steel Nipple – Threaded Fitting for Corrosion-Resistant Piping Systems

The 1/2" x 2-1/2" galvanized steel nipple is a straight, fully threaded pipe segment designed to connect two female-threaded fittings in residential, commercial, or light industrial applications. Manufactured from carbon steel and protected with a hot-dip galvanized zinc coating, it provides corrosion resistance and mechanical strength in potable water and general-purpose systems.

Product Features

• Material: Carbon steel with ASTM-compliant hot-dip galvanization
• Nominal Size: 1/2 inch
• Length: 2-1/2 inches overall
• Thread Type: NPT (National Pipe Thread), male x male, full-threaded
• Finish: Zinc coating enhances corrosion resistance for above-ground use

Performance and Durability

• Engineered for use in low- to medium-pressure systems
• Withstands exposure to water, air, and non-corrosive gases
• Maintains structural integrity in interior and non-buried exterior environments

Common Applications

• Water distribution systems in residential or commercial buildings
• Compressed air lines and non-potable water applications
• Mechanical and maintenance piping in utility rooms or HVAC systems

Installation Guidelines

Install using industry-standard techniques for threaded steel piping. Apply PTFE tape or thread compound to male threads before joining to ensure a leak-free seal. Avoid over-torquing to protect thread integrity. Use with galvanized or compatible threaded fittings; not suitable for underground or chemical service unless specified by the project engineer.

Compliance and Manufacturing Standards

• Threads comply with ANSI/ASME B1.20.1
• Galvanized coating conforms to ASTM A153 or A123 (varies by manufacturer)
• Base pipe typically meets ASTM A53 or A106 Grade B specifications

Note:

This fitting is not recommended for use with acidic fluids or systems exposed to high chlorides. For buried installations or chemical exposure, consult project specifications and material compatibility charts.

The 1/2" x 2-1/2" galvanized steel nipple offers a dependable solution for threading pipe sections in general plumbing and mechanical systems. Its galvanized protection and NPT threading make it a reliable component for long-term piping integrity in standard environments.
