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

1-1/4" x 2-1/2" Galvanized Steel Nipple – Threaded Connection for Durable Piping Systems

Engineered for dependable mechanical performance, the 1-1/4" x 2-1/2" galvanized steel nipple is used to extend or connect sections of pipe in non-potable water, gas, and low-pressure steam systems. Its corrosion-resistant zinc coating offers added protection in demanding environments, making it a reliable option for commercial and industrial installations.

Product Advantages

• Corrosion Resistance: Hot-dip galvanized finish protects the steel substrate against rust, especially in moisture-prone applications.
• Machined NPT Threads: Conforms to ANSI B1.20.1 standards for tight, reliable sealing in threaded piping assemblies.
• Consistent Wall Thickness: Fabricated from schedule 40 pipe stock to ensure uniform strength across the fitting.
• Dimensional Stability: Precision-cut length of 2-1/2" ensures compatibility with fittings in tight or confined system layouts.
• Meets Industry Standards: Suitable for use in systems governed by ASME B31.3 and applicable ASTM specifications for galvanized pipe and nipples.

Common Applications

This 1-1/4" galvanized steel nipple is frequently used in the following contexts:

• Hydronic heating system pipe extensions and unions
• Low-pressure natural gas or propane lines (where permitted by code)
• Industrial or agricultural water lines requiring corrosion-resistant steel connections
• Mechanical room piping layouts involving threaded cast iron or malleable fittings

Installation Notes

• Apply pipe thread sealant or PTFE tape to male threads before assembly to ensure a leak-resistant seal.
• Tighten using pipe wrenches on flats near each threaded end to avoid damaging the zinc coating.
• Not recommended for use with potable water systems unless specified as NSF-61 compliant.

Technical Specifications

• Nominal Pipe Size: 1-1/4"
• Overall Length: 2-1/2"
• Material: Schedule 40 galvanized carbon steel
• Thread Type: Male NPT both ends
• Standard Compliance: ASTM A53, ANSI/ASME B1.20.1

Built for resilience in harsh or demanding plumbing systems, this 1-1/4" x 2-1/2" galvanized steel nipple is a trusted component for high-integrity threaded connections. Its precision threading and protective coating help ensure a long service life in mission-critical installations.
