1-1/2 inch x 5 inch Galvanized Steel Nipple

1-1/2" x 5" Galvanized Steel Nipple – Threaded Connection for High-Strength Plumbing Applications

The 1-1/2" x 5" Galvanized Steel Nipple is a heavy-duty fitting designed for threaded pipe-to-pipe connections in pressure-rated systems. Manufactured from carbon steel and hot-dip galvanized to ASTM A153 specifications, this nipple offers superior corrosion resistance for both interior and exterior plumbing use.

Its threaded male ends conform to ANSI B1.20.1 standards, allowing for easy integration with compatible galvanized or black malleable iron fittings. Ideal for both new construction and retrofit scenarios, this component is engineered for consistent performance across a range of water supply, gas distribution, and industrial fluid systems.

Performance Advantages

• ✅ Galvanized Coating – Zinc coating provides protection against rust and scale, particularly in moist or humid conditions.
• ✅ Thread Integrity – Precision-machined male threads offer consistent sealing surfaces, helping to prevent joint failure under pressure.
• ✅ Mechanical Strength – Fabricated from Schedule 40 steel pipe for resistance to deformation and vibration fatigue.

Specifications

• Nominal Size: 1-1/2 inch
• Length: 5 inches
• Material: Galvanized carbon steel
• Thread Type: Male NPT (National Pipe Thread)
• Compliance: Meets ASTM A733, ANSI B1.20.1, and ASTM A53 Type E or S standards

Installation Guidelines

Apply thread sealant or PTFE tape to the male threads before tightening. Use appropriate torque levels and avoid over-threading, which can compromise seal integrity. For systems with thermal cycling or vibration, confirm that all mating components are compatible in material and schedule rating.

Typical Applications

• Potable and non-potable water distribution
• Compressed air and low-pressure steam systems
• Hydronic heating loops and boiler piping
• Gas service lines (when approved by local code)

Did You Know?

Hot-dip galvanizing forms a metallurgical bond between zinc and steel, creating a sacrificial layer that continues to protect the base metal even if the surface is scratched.

For mechanical contractors and plumbing professionals requiring strength, corrosion resistance, and dimensional consistency, the 1-1/2" x 5" Galvanized Steel Nipple delivers dependable performance in high-demand systems. Specify with confidence for your next pipe system installation or repair.
