1-1/4 inch x 6 inch Galvanized Steel Nipple

1-1/4" x 6" Galvanized Steel Nipple – Threaded Schedule 40 Pipe Fitting

This 1-1/4" x 6" galvanized steel nipple is fabricated from Schedule 40 welded steel pipe and hot-dip galvanized in accordance with ASTM A53 standards. The zinc coating provides enhanced resistance to corrosion in non-aggressive water supply systems, compressed air lines, and mechanical piping applications.

The nipple features male NPT threads on both ends for connection to compatible female-threaded components, allowing for rigid, pressure-rated joints in both horizontal and vertical pipe runs. Manufactured to precise tolerances, it ensures consistent fit and sealing when used with approved sealants.

Technical Highlights

• ✅ Material: Carbon steel with hot-dip galvanized finish per ASTM A53, Type E or S
• ✅ Size: 1-1/4" nominal pipe size (NPS)
• ✅ Length: 6" overall length
• ✅ Thread Standard: ANSI B1.20.1 (NPT - National Pipe Thread Taper)
• ✅ Wall Thickness: Schedule 40
• ✅ Pressure Rating: Conforms to system design parameters per ASME B31.1 or B31.3 as applicable

Application Scope

This steel nipple is commonly used in:

• • Low-pressure water distribution systems
• • HVAC piping, including chilled and hot water loops
• • Air compressor lines and pneumatic systems
• • Mechanical support assemblies requiring structural pipe fittings

Installation Requirements

Apply a suitable pipe thread compound or PTFE tape to male threads prior to assembly. Avoid cross-threading and over-tightening to prevent thread deformation or sealing failure. Pipe wrenches or strap wrenches should be used as required, ensuring torque is appropriate to thread engagement and pipe size. Install in accordance with project specifications and relevant codes.

Material Insight

Galvanized pipe is widely specified in non-potable water and mechanical systems where cost-effective corrosion resistance is needed. The hot-dip galvanizing process bonds zinc to steel, forming a metallurgically bonded coating that resists atmospheric and moisture-driven corrosion over extended periods.
