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

1-1/2" x 2-1/2" Galvanized Steel Nipple – Built for Demanding Piping Systems

The 1-1/2" x 2-1/2" Galvanized Steel Nipple is engineered for applications where durability, corrosion resistance, and precise threading are essential. This schedule 40 nipple is fabricated from carbon steel and hot-dip galvanized in accordance with ASTM A153 specifications, offering long-term performance in both residential and commercial systems.

Its short length and standard NPT male threads make it ideal for coupling valves, fittings, and pipe segments in confined or critical areas of water distribution, air lines, or non-corrosive fluid systems.

Performance Features

• Material: Carbon steel with hot-dip galvanized finish
• Size: 1-1/2 inch nominal pipe size x 2-1/2 inch length
• Thread Type: NPT (National Pipe Tapered) – male on both ends
• Pressure Rating: Suitable for use in systems rated up to 150 psi at ambient temperature
• Corrosion Protection: Zinc coating provides excellent resistance to oxidation and environmental exposure

Installation Guidelines

Threaded galvanized nipples should be installed using standard wrenching methods and compatible with fittings that conform to ASME B1.20.1 thread standards. Apply a compatible thread sealant (such as PTFE tape or pipe dope) to prevent leakage. Avoid using in systems carrying potable water unless local code permits galvanized steel.

Typical Applications

• Hydronic heating loops
• Gray water and non-potable water systems
• Compressed air distribution
• Process and utility piping in light industrial settings

Did You Know?

Galvanized steel fittings are often specified in mechanical rooms and utility chases due to their high mechanical strength and ability to resist scale formation over extended service life.

The 1-1/2" x 2-1/2" Galvanized Steel Nipple is a reliable solution when strength and corrosion resistance are paramount. Its precision threading and rugged finish ensure a secure, long-lasting connection—suitable for professionals seeking consistent performance under pressure.
