1-1/2 inch x 5-1/2 inch Galvanized Steel Nipple

1-1/2 Inch x 5-1/2 Inch Galvanized Steel Nipple – Threaded Pipe Segment for General Piping Systems

The 1-1/2 inch x 5-1/2 inch Galvanized Steel Nipple is a straight pipe fitting designed for joining threaded steel pipe sections in water, air, or low-pressure applications. Its hot-dip galvanized coating provides additional corrosion resistance, making it suitable for use in non-potable water systems and mechanical assemblies requiring moderate exposure protection.

Functional Characteristics

Engineered for compatibility with malleable iron and steel fittings, this nipple is commonly integrated into commercial and residential piping layouts where strength and joint integrity are essential:

• ✅ Precision-Formed Threads: Machined to National Pipe Thread (NPT) standards for accurate engagement with mating components.
• ✅ Galvanized Coating: Zinc-coated via hot-dip process to help resist oxidation in non-corrosive and mildly corrosive environments.
• ✅ Uniform Wall Thickness: Fabricated to support pressure consistency across short span connections in rigid piping systems.

Contractor Advantages

Use of standardized steel nipples ensures time efficiency and dimensional predictability during assembly. Key benefits include:

• ✅ Thread Integrity: Straight, clean threading promotes dependable mechanical sealing when used with approved sealants or tape.
• ✅ Load Support: Steel composition supports structural pipe alignment and maintains integrity under mechanical stress.
• ✅ Compliance Support: Fabricated to meet typical manufacturing tolerances and performance expectations outlined in ANSI/ASME standards.

Specifications

• Material: Carbon steel with hot-dip galvanized coating
• Nominal Size: 1-1/2 inch NPT
• Length: 5-1/2 inches overall
• Ends: Male NPT threads (both ends)
• Standard Compliance: NPT threading per ANSI B1.20.1

Typical Applications

This galvanized nipple is commonly installed in pump discharge lines, HVAC piping, gray water systems, mechanical enclosures, and general-purpose liquid transfer assemblies. It is not intended for use in potable water systems unless specified by local code or additional treatment.

Installation Note

Threaded steel fittings should be installed using compatible thread sealant or PTFE tape. Avoid over-torquing to maintain thread integrity and minimize risk of splitting or thread deformation. Installation should conform to applicable plumbing or mechanical codes.

The 1-1/2 inch x 5-1/2 inch Galvanized Steel Nipple offers reliable joint strength, dimensional precision, and material durability in environments where corrosion resistance and mechanical stability are required. Suitable for service professionals working across commercial and industrial piping systems.
