1/4 inch x 2 inch Galvanized Steel Nipple

1/4" x 2" Galvanized Steel Nipple – Standard Threaded Pipe for General Use

The 1/4" x 2" Galvanized Steel Nipple is designed to provide a secure threaded connection between two female pipe fittings of the same diameter. Fabricated from galvanized steel, this fitting is suitable for use in low- to medium-pressure plumbing, air, and mechanical piping systems where corrosion resistance is required.

This straight nipple is commonly specified in non-potable water lines, compressed air systems, and some fire protection applications where code allows. The zinc coating helps mitigate surface oxidation in dry or mildly damp environments, extending service life compared to bare steel alternatives.

Key Performance Characteristics

• ✅ Material: Carbon steel with zinc galvanizing for moderate corrosion resistance
• ✅ Threading: NPT (National Pipe Taper), meeting ANSI/ASME B1.20.1 specifications
• ✅ Size: 1/4 inch nominal pipe size, 2-inch overall length
• ✅ Connection: Male thread x Male thread
• ✅ Standard: Complies with applicable ASTM and ASME mechanical fitting standards

Installation and Usage Guidelines

To ensure a leak-resistant joint, use compatible thread sealant or PTFE tape during installation. The fitting should be tightened with appropriate hand tools, avoiding excessive torque which can crack adjoining fittings or distort threads. This nipple is not intended for use in potable water systems unless explicitly rated and certified for such use.

Typical Applications

• General plumbing connections in non-potable systems
• Low-pressure compressed air piping
• Drainage and venting systems
• Fire protection piping where permitted

Note:

Galvanized steel should not be directly connected to copper piping due to the risk of galvanic corrosion. Always consult local code requirements and material compatibility prior to installation.
