1 inch x 4 inch Galvanized Steel Nipple

1" x 4" Galvanized Steel Nipple – Threaded Connector for Piping Applications

The 1" x 4" galvanized steel nipple is a threaded pipe fitting used to extend or join sections of pipe within pressurized or low-pressure systems. Manufactured from carbon steel and finished with a hot-dip galvanized coating, this component provides corrosion resistance in environments subject to moisture or variable temperature exposure.

Fabricated to industry standards, the nipple features precision-cut male NPT threads at both ends, ensuring compatibility with standard fittings and minimizing the risk of joint failure under load. Its 4-inch length offers flexibility in installations where space and alignment requirements must be carefully managed.

Performance and Functional Benefits

• ✅ Corrosion Protection Zinc-coated surface resists rust, extending the service life in wet or exposed conditions.
• ✅ Schedule-Rated Steel Compatible with Schedule 40 piping systems, suitable for water, air, and non-potable fluids.
• ✅ Reliable Thread Engagement NPT threads conform to ANSI B1.20.1 standards, supporting leak-tight assemblies with thread sealant or PTFE tape.
• ✅ Versatile Length 4-inch size accommodates system layout adjustments without excessive takeoff modification.

Material and Dimensional Specifications

• Material: Hot-dip galvanized carbon steel
• Nominal Size: 1 inch diameter
• Length: 4 inches overall
• Connection: Male National Pipe Thread (NPT) – both ends

Installation Requirements

To ensure proper sealing and joint integrity, use a compatible thread sealant or PTFE tape. Joints should be tightened to manufacturer-recommended torque specifications to avoid thread damage or misalignment. Installation in systems subject to thermal expansion or vibration may require union fittings or supports to reduce mechanical stress.

Application Areas

This galvanized nipple is commonly used in:

• Water distribution and supply piping (non-potable)
• Hydronic heating and cooling systems
• Compressed air lines in maintenance facilities
• Low-pressure gas distribution (verify local code compliance)

Material Performance Note

Galvanized steel components are not recommended for use in potable water systems due to the potential for zinc leaching. However, they are highly suitable for structural and utility piping where corrosion resistance and mechanical strength are required.

The 1" x 4" galvanized steel nipple offers dependable threaded connectivity in a range of building system applications. Its corrosion-resistant finish and precision-machined threads make it a staple fitting for commercial, mechanical, and industrial pipework assemblies.
