3/4 inch x 3 inch Galvanized Steel Nipple

3/4" x 3" Galvanized Steel Pipe Nipple – Threaded for High-Durability Applications

The 3/4" x 3" Galvanized Steel Nipple is a precision-machined fitting used to extend pipe runs and connect threaded components in water, air, or low-pressure steam systems. Manufactured from welded steel pipe and hot-dip galvanized to ASTM standards, this fitting provides strong resistance to rust and corrosion in demanding service environments.

This nipple features NPT (National Pipe Thread) tapered threads on both ends, allowing secure integration into existing galvanized piping assemblies. Its short length and rigid construction make it ideal for compact installations where space constraints exist.

Performance and Technical Specifications

• Size: 3/4" NPT male x 3" overall length
• Material: Welded carbon steel, hot-dip galvanized
• Thread Standard: ANSI/ASME B1.20.1 (NPT)
• Pipe Schedule: Schedule 40
• Pressure Rating: Up to 150 PSI for water/oil/air (WOG) in non-corrosive environments

Key Applications

This galvanized steel nipple is used in a variety of mechanical and plumbing systems, including:

• Water distribution and supply lines
• HVAC system pipe runs
• Low-pressure process piping
• Compressed air service lines
• General utility piping in industrial and commercial facilities

Installation Guidelines

• Use thread sealant (PTFE tape or thread compound) to ensure leak-free joints
• Wrench-tighten using the wrench flats provided on adjacent pipe or fittings
• Inspect galvanized coating for uniformity and avoid exposure to aggressive chemicals

Advantages of Galvanized Steel Nipples

• Corrosion Protection: Zinc coating resists rust in humid and outdoor environments
• Mechanical Strength: Rigid and impact-resistant for structural durability
• Threaded Ends: Compatible with a wide range of galvanized pipe fittings
• Reliable Transition: Facilitates spacing or length adjustments between connections

Note:

Galvanized steel nipples are not suitable for use in potable water systems in all jurisdictions. Verify local codes prior to installation. Do not use in applications where corrosive agents may compromise the zinc coating.

The 3/4" x 3" Galvanized Steel Nipple is a durable, code-compliant solution for contractors requiring consistent quality in pressure-rated installations. Ideal for use in both new construction and retrofit applications where galvanized systems are required.
