2 inch x 8 inch Galvanized Steel Nipple

2" x 8" Galvanized Steel Nipple – Heavy-Duty Pipe Connector

The 2" x 8" galvanized steel nipple is a robust fitting engineered for connecting sections of pipe in systems requiring strength, durability, and corrosion resistance. Manufactured from schedule 40 steel pipe and hot-dip galvanized to ASTM A153 standards, this nipple is suitable for demanding installations in both residential and commercial plumbing and mechanical systems.

Threaded on both ends with NPT (National Pipe Tapered) threads, this fitting allows for secure, leak-resistant connections with other compatible threaded components. Its 8-inch length is ideal for extending pipe runs, creating offsets, or bridging gaps between system elements while maintaining consistent internal flow characteristics.

Performance Features

• Material: Schedule 40 galvanized steel for enhanced strength and extended service life.
• Threading: Precisely cut NPT threads ensure a tight mechanical seal with standard fittings.
• Corrosion Protection: Hot-dip galvanized coating provides resistance against rust and atmospheric oxidation.
• Dimensions: 2" nominal diameter x 8" overall length.
• Operating Pressure: Rated for use in low- to moderate-pressure applications, including water and air lines.

Common Applications

• Hydronic heating system pipe extensions
• Potable and non-potable water distribution lines
• Industrial and mechanical piping frameworks
• Outdoor piping systems where corrosion resistance is essential

Installation Guidelines

For optimal performance, install using pipe thread sealant or PTFE tape on male threads. Ensure threads are clean and undamaged prior to assembly. Use appropriate torque during tightening to avoid thread galling or deformation. Compatible with other steel, brass, or malleable iron threaded fittings in accordance with ANSI standards.

Certifications & Compliance

• ASTM A733 (nipple manufacturing standard)
• ASTM A53 / A106 Grade B (pipe specification)
• ASTM A153 (zinc coating specification)

The 2" x 8" galvanized steel nipple provides a trusted solution for contractors who need dependable, corrosion-resistant connections in their piping systems. Built to meet rigorous quality standards, this fitting ensures reliable performance in a range of plumbing and mechanical applications.
