1-1/4 inch x 8 inch Galvanized Steel Nipple

1-1/4" x 8" Galvanized Steel Nipple – Threaded Schedule 40 Pipe for Pressure and Water Systems

The 1-1/4 inch x 8 inch galvanized steel nipple is a straight pipe segment with male NPT threads on both ends. Manufactured from schedule 40 steel pipe, it is hot-dip galvanized to ASTM A153 standards, providing corrosion resistance for water and air systems. This nipple is commonly used for extending pipe runs, making pipe connections in confined areas, or adapting to fittings in plumbing, mechanical, and process piping systems.

Product Features

• ✅ Material: Schedule 40 carbon steel
• ✅ Galvanized Coating: Hot-dip zinc coating for corrosion protection per ASTM A123/A153
• ✅ Ends: Threaded male NPT both ends (ANSI B1.20.1)
• ✅ Length: 8 inches overall
• ✅ Nominal Size: 1-1/4 inch diameter

Applications

This galvanized nipple is suited for use in low-pressure plumbing and mechanical piping systems including:

• • Cold potable water distribution
• • Non-potable water systems
• • Compressed air lines (dry systems)
• • Low-pressure HVAC and hydronic applications

Installation Guidelines

Install using compatible threaded fittings and appropriate joint sealants such as PTFE tape or thread compound. Hand-tighten followed by 1–2 turns with a wrench, avoiding over-tightening which may damage threads. Galvanized steel should not be used in systems where exposure to chlorinated water or acids may degrade the zinc coating.

Code Compliance

Meets dimensional requirements of ASTM A733 and threading standards per ANSI/ASME B1.20.1. Galvanized products are approved for use in plumbing systems where corrosion resistance is required by code or design specification.

Note:

Use of galvanized steel is not recommended for natural or LP gas systems unless explicitly approved by the authority having jurisdiction. For hot water recirculating systems, consider alternate materials to reduce long-term scaling or coating degradation.

The 1-1/4" x 8" galvanized nipple delivers strength, corrosion protection, and reliable fit for industrial-grade piping connections. Specified for projects requiring threaded joints in water supply or mechanical lines where longevity and compliance are priorities.
