3/4 inch x 10 inch Galvanized Steel Nipple

3/4" x 10" Galvanized Steel Nipple – Threaded Connector for Corrosion-Resistant Piping

The 3/4" x 10" Galvanized Steel Nipple is a straight pipe segment with male National Pipe Thread (NPT) ends, intended for use in threaded piping systems that require corrosion resistance and mechanical durability. Constructed from carbon steel and coated with a layer of zinc through the hot-dip galvanizing process, this fitting is suitable for potable water, air, and non-aggressive fluid distribution systems.

With a 10-inch overall length and uniform wall thickness, this nipple is used to extend pipe runs or provide spacing between valves, fittings, and structural connections in rigid systems. It is commonly installed in both residential and commercial construction settings, particularly where exposure to moisture or atmospheric corrosion is a factor.

Key Features and Applications

• ✅ Hot-Dip Galvanized Coating: Zinc barrier resists oxidation and surface corrosion in wet or humid environments.
• ✅ NPT Threaded Ends: Precision-machined male threads ensure compatibility with standard fittings and valves.
• ✅ Medium-Pressure Service: Supports fluid and air conveyance in low to moderate pressure systems, depending on pipe schedule and application.
• ✅ Potable Water Use: Manufactured to meet lead-free requirements where applicable for drinking water lines.
• ✅ Cross-System Compatibility: Used in HVAC circuits, water supply piping, pump discharge lines, and process plumbing assemblies.

Technical Specifications

• Nominal Size: 3/4 inch
• Length: 10 inches
• Material: Carbon steel, hot-dip galvanized (per ASTM A53 or A733)
• Thread Type: NPT (ASME B1.20.1)
• Use Category: Non-corrosive and potable fluid transport; suitable for above-ground and indoor installations

Installation Guidelines

Apply thread sealant (pipe dope) or PTFE tape to male threads prior to assembly. Tighten using two pipe wrenches to ensure uniform engagement and prevent overstressing the joint. Check for system pressure compatibility before energizing. This nipple is not recommended for gas service unless specified by local code and applicable certification.

Usage Scenarios

Common installations include water distribution manifolds, mechanical room supply lines, fire protection support loops (non-sprinkler), and irrigation header systems. The corrosion-resistant coating makes it a preferred option for environments subject to condensation, intermittent contact with water, or mild outdoor exposure.

Material Note

Galvanized nipples are not recommended for use with acidic or alkaline chemicals, or in environments where the zinc coating may degrade due to electrochemical reactions (e.g., in dissimilar metal contact with copper under high moisture conditions).

The 3/4" x 10" Galvanized Steel Nipple is a standard component in threaded piping assemblies where corrosion resistance, mechanical strength, and code compliance are required for long-term service.
