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

1-1/2” x 3” Galvanized Steel Nipple – Industrial-Grade Performance for Pressurized Systems

Engineered for strength and long-term service, the 1-1/2” x 3” Galvanized Steel Nipple is designed to provide durable threaded connections in plumbing and mechanical applications. Manufactured from zinc-coated steel, this fitting resists rust and oxidation, making it a dependable choice for high-pressure water, air, or non-corrosive gas systems.

This nipple is precision-machined to NPT threading standards and offers a reliable seal when properly installed with approved thread sealants. Its robust build and compatibility with standard galvanized fittings make it an essential component in both new installations and system retrofits.

Key Performance Features

• ✅ Hot-Dip Galvanized Finish – Enhances corrosion resistance, especially in humid or semi-exposed locations.
• ✅ Consistent Thread Engagement – Machined threads ensure uniform fit and minimal risk of cross-threading or galling.
• ✅ Schedule 40 Wall Thickness – Suitable for standard pressure applications in residential, commercial, and light industrial systems.

Installation Guidance

This fitting is suitable for use with standard pipe wrenches and thread sealants (pipe dope or PTFE tape). Installation should follow local plumbing codes and involve correct torque application to avoid over-threading or damage. Use in systems where galvanic compatibility with other metals is maintained is recommended to preserve material integrity.

Technical Details

• Size: 1-1/2” nominal pipe size
• Length: 3” overall
