Standard 1/2 Inch GI Long Thread Nipple, Galvanized Iron Pipe Fitting

1/2 Inch GI Long Thread Nipple

The Standard 1/2 GI Nipple serves as a critical connector for extending or joining pipe runs in pressurized fluid systems. This galvanized iron fitting features precision-cut threads designed to withstand heavy-duty mechanical stress. It is suitable for water distribution, compressed air lines, and industrial plumbing applications.

Built for the Job

Plumbers and facility managers utilize this component when standard pipe lengths do not meet specific site requirements. The extended threading provides the necessary clearance for navigating through thick masonry or connecting to recessed valves. Its heavy-wall construction ensures structural integrity under high pressure and temperature fluctuations. This fitting is a staple in both residential irrigation and commercial fire protection systems.

• Extending branch lines from main water headers.

• Connecting shower arms or tap extensions through tiled walls.

• Installing pressure gauges and sensors in industrial manifolds.

Product Highlights

Corrosion Resistance

A hot-dipped zinc coating protects the base metal from oxidation and internal scaling.

Thread Performance

• BSP standard threading for universal compatibility with 15mm fittings.
• Deep-cut threads for secure, leak-proof engagement with PTFE tape.

On-Site & Workshop Notes

• Always apply a high-quality thread sealant or pipe dope to the external threads before installation.

• Avoid over-tightening with a pipe wrench to prevent stripping the zinc coating or cracking the fitting.

• Check local building codes for compatibility when using this material for gas line extensions.

• Store in a dry area to maintain the integrity of the protective surface before the job begins.
