3 inch x Close Galvanized Steel Nipple

3" Galvanized Steel Nipple – Threaded Connector for Pressurized Systems

The 3" Galvanized Steel Nipple is a straight, close-length pipe fitting designed for joining two female-threaded components in pressurized plumbing or mechanical piping systems. Made from Schedule 40 carbon steel and hot-dip galvanized to ASTM A153 standards, it offers reliable resistance to corrosion in both indoor and outdoor environments.

This nipple is commonly used for water distribution, low-pressure steam, and air handling systems where a short threaded extension is needed. It features NPT (National Pipe Tapered) threads on both ends, enabling a tight, leak-resistant mechanical joint when properly sealed with thread compound or PTFE tape.

Key Features

• ✅ Material: Carbon steel, hot-dip galvanized for corrosion protection
• ✅ Thread Type: NPT on both ends, per ANSI B1.20.1 specifications
• ✅ Length: 3 inches overall; may vary slightly due to threading tolerance
• ✅ Nominal Size: 3/8", compatible with standard Schedule 40 threaded pipe systems
• ✅ Application: Suitable for use in water supply, HVAC, compressed air, and non-potable systems

Installation Guidelines

Apply an approved thread sealant or PTFE tape to male threads before installation. Thread into female fittings using a pipe wrench, taking care not to overtighten and risk distortion of threads or damage to surrounding components. Always confirm pressure ratings and thread engagement meet job specifications and local code requirements.

Use Cases

This galvanized steel nipple is regularly employed in residential and commercial building systems for short-length connections in risers, manifolds, or as extension pieces. It is particularly effective in areas exposed to atmospheric moisture or low-intensity corrosive conditions where galvanized protection is beneficial.

Compliance Note

Galvanized pipe and nipples are generally not recommended for potable water systems in areas where internal scaling or lead contamination is a concern. Always verify local code requirements before use in drinking water lines.

For pressure-rated mechanical systems requiring a robust threaded connection, this 3" galvanized steel nipple offers performance backed by proven material durability and manufacturing consistency. Install with confidence in commercial, industrial, or maintenance settings where steel is specified. ????️
