1/2 inch x 2 inch Galvanized Steel Nipple

1/2" x 2" Galvanized Steel Pipe Nipple – Threaded Schedule 40 Fitting

The 1/2" x 2" Galvanized Steel Pipe Nipple is a straight coupling component designed for joining two female-threaded pipe sections in potable water, non-potable, or HVAC systems. Fabricated from Schedule 40 carbon steel and hot-dip galvanized per ASTM A153, this fitting provides enhanced resistance to corrosion and mechanical wear.

With NPT threads machined to ANSI B1.20.1 specifications, it delivers a dependable seal in pressurized and non-pressurized plumbing systems. The 2" length accommodates short-run connections or system terminations where precision and strength are required.

Technical Specifications

• Nominal Size: 1/2"
• Length: 2 inches
• Material: Carbon Steel
• Finish: Galvanized (hot-dip zinc coating)
• Wall Type: Schedule 40
• Thread Standard: ANSI/ASME B1.20.1 (NPT - Male x Male)
• Pressure Rating: 150 PSI WOG (non-shock)
• Compliance: Meets ASTM A733 and A53 standards for pipe nipples

Application & Use

This fitting is typically used in:

• Potable and non-potable water distribution systems
• Natural gas and LP gas piping (when compliant with local code)
• Mechanical and hydronic heating systems
• Compressed air lines in industrial settings

Installation Guidance

Proper installation requires the use of thread sealant (PTFE tape or approved pipe dope) to ensure a leak-proof joint. Thread engagement should not exceed 3.5 turns beyond hand tight. Avoid overtightening, which may distort the threads and compromise seal integrity. Compatible only with other NPT-threaded galvanized or black pipe fittings and nipples of matching nominal size.

Performance Note

Galvanized steel nipples are recommended where corrosion resistance is required in humid or outdoor environments. They are not intended for use with acidic fluids or systems exposed to highly corrosive agents. For steam service, confirm rating compatibility prior to installation.

Professionals rely on galvanized Schedule 40 steel nipples like this for their strength, dimensional accuracy, and longevity in demanding installations. Use where code-compliant, long-term threaded pipe connections are required.
