1 inch x 3-1/2 inch Galvanized Steel Nipple

Galvanized Steel Nipple 1" x 3-1/2" – Built for Pressure Integrity and Corrosion Resistance

The 1" x 3-1/2" Galvanized Steel Nipple is designed for joining two female-threaded pipe sections in water, air, or low-pressure steam systems. Manufactured from welded steel pipe and hot-dip galvanized to ASTM A153 standards, this fitting offers robust performance in environments where corrosion resistance and mechanical strength are essential.

Threaded ends conform to ASME B1.20.1, providing reliable sealing and compatibility with standard threaded pipe and fittings. The uniform galvanizing process ensures a consistent coating thickness for dependable long-term use, particularly in systems exposed to moisture, fluctuating temperatures, or light chemicals.

Performance Highlights

• Connection: Male NPT x Male NPT
• Material: Welded steel with hot-dip galvanized finish
• Length: 3-1/2 inches (Close Nipple Category)
• Nominal Pipe Size (NPS): 1 inch
• Thread Standard: ANSI/ASME B1.20.1 (tapered pipe thread)
• Compliance: Meets applicable ASTM and ANSI specifications

Typical Applications

• Water supply systems (non-potable)
• Low-pressure air lines
• Hydronic heating loops
• Agricultural and industrial water transfer

Installation Notes

Use an approved pipe sealant or PTFE tape to achieve a leak-free joint. Ensure proper alignment and thread engagement to prevent cross-threading. Not intended for underground use without additional protective treatment.

Did You Know?

Galvanized steel pipe is coated with a zinc layer that forms a barrier against corrosion and can also self-heal small scratches, making it ideal for exposed or humid conditions.

The Galvanized Steel Nipple 1" x 3-1/2" delivers dependable performance in threaded piping systems. With its corrosion-resistant finish and precise threading, this fitting is trusted by contractors for pressure-rated applications across a wide range of environments.
