3/4 inch x 4 inch Galvanized Steel Nipple

3/4" x 4" Galvanized Steel Nipple – Threaded Schedule 40 Fitting

The 3/4" x 4" Galvanized Steel Nipple is manufactured from schedule 40 carbon steel pipe and hot-dip galvanized for added corrosion protection. Designed for use in pressure-rated systems, it provides a robust solution for connecting threaded pipe runs in both potable water and mechanical applications.

Each nipple is precision-threaded to ANSI B1.20.1 NPT standards, ensuring compatibility with malleable iron, cast fittings, and other galvanized steel components. The galvanized coating provides extended service life in moist environments, making this fitting suitable for interior and select exterior installations.

Technical Specifications

• Nominal Size: 3/4 inch
• Length: 4 inches (end-to-end)
• Wall Thickness: Schedule 40
• Material: Carbon Steel (ASTM A53/A106)
• Finish: Hot-dip galvanized
• Threading: NPT male x male (ANSI B1.20.1)

Key Advantages

• ✅ Corrosion Protection – Galvanized exterior resists oxidation in wet environments and extends component life.
• ✅ High Mechanical Strength – Schedule 40 pipe body provides resistance to pressure and impact in industrial and plumbing applications.
• ✅ Threaded for Standard Fittings – Compatible with commonly used galvanized and black malleable iron pipe systems.
• ✅ Code-Compliant Design – Meets applicable plumbing and mechanical codes for potable and non-potable systems.

Installation Considerations

For best results, apply appropriate pipe joint compound or PTFE tape to male threads before tightening. Over-torquing should be avoided to preserve thread integrity. Nipple should be installed using tools that prevent galling or deformation of the pipe body and threads.

Common Applications

This galvanized nipple is used in a wide range of commercial and residential systems including water distribution lines, compressed air systems, heating circuits, and non-corrosive fluid transfer. Ideal for both new builds and retrofits where corrosion resistance and thread compatibility are required.

Did You Know?

Hot-dip galvanized pipe nipples are widely used in mechanical and plumbing installations because the zinc coating offers both barrier and sacrificial protection, significantly reducing internal and external corrosion in standard water system conditions.

Choose the 3/4" x 4" Galvanized Steel Nipple for secure, pressure-rated connections in galvanized pipe systems. Its durable finish, standardized threading, and high structural integrity make it a staple for professionals across the plumbing and mechanical trades.
