1-1/4 inch x 10 inch Galvanized Steel Nipple

1-1/4" x 10" Galvanized Steel Nipple – Threaded Connector for Corrosion-Resistant Pressure Piping

The 1-1/4" x 10" Galvanized Steel Nipple is a straight, male-threaded fitting used in rigid piping systems that require a durable, corrosion-resistant connection. Manufactured from carbon steel and hot-dip galvanized to ASTM specifications, this nipple is commonly specified in water distribution, HVAC, and low-pressure steam systems where exposure to moisture or atmospheric elements is expected.

It is designed for joining two female-threaded components such as tees, valves, or couplings, and is suitable for both horizontal and vertical runs. The 10" length provides spacing between fittings while maintaining alignment and system integrity.

Functional Features

• ✅ Hot-Dip Galvanized Coating: Provides a protective zinc layer that resists corrosion in interior and exterior environments.
• ✅ Threaded NPT Ends: Precision-cut male National Pipe Threads ensure proper sealing with compatible components when used with appropriate thread sealant.
• ✅ Carbon Steel Core: Offers mechanical strength for pressure-rated installations in residential, commercial, and light industrial systems.
• ✅ Standard Schedule Wall: Manufactured to meet applicable wall thickness tolerances and dimensional standards.

Technical Specifications

• Nominal Diameter: 1-1/4 inch
• Length: 10 inches
• Material: Carbon steel with hot-dip galvanized coating
• Thread Type: NPT (ASME B1.20.1)
• Manufacturing Standards: Typically conforms to ASTM A733 and ASTM A53

Installation Considerations

Install using appropriate thread sealant or PTFE tape. Apply torque with two pipe wrenches to avoid deformation and ensure uniform engagement. Verify compatibility with system pressure ratings and confirm that pipe material and coating are suitable for the intended application. Avoid using galvanized pipe in systems that include corrosive media or dissimilar metals without isolation methods.

Common Applications

This nipple is frequently installed in water supply systems, mechanical piping layouts, process water systems, and structural pipe assemblies where corrosion protection and moderate pressure ratings are required. It is appropriate for above-ground use in dry or humid mechanical environments, and for buried service when protected per code.

Material Insight

Galvanized steel has been used for decades in plumbing and mechanical applications due to its combination of strength and rust resistance. Its zinc coating protects the underlying steel from oxidation, especially in non-potable or utility-grade water systems. It is not recommended for potable hot water lines where long-term scale formation may occur.

The 1-1/4" x 10" Galvanized Steel Nipple provides a durable and reliable solution for threaded piping systems where corrosion resistance, pressure tolerance, and code compliance are required.
