1 inch x 3-1/2 inch Black Steel Nipple
211 Available At All US Supply Locations
1" x 3-1/2" Black Steel Nipple – Built for Strength and Pressure Integrity
The 1" x 3-1/2" Black Steel Nipple is designed for robust threaded connections in high-pressure systems. Commonly used in gas, air, and water supply lines, this fitting ensures mechanical strength and resistance to thermal and mechanical stress. Its consistent performance in industrial and commercial applications makes it a reliable component in demanding installations.
Contractor-Grade Performance
- ✅ Seamless Steel Construction – Manufactured from high-strength black steel, suitable for heavy-duty applications and threaded piping systems.
- ✅ Precision Threading – Machined NPT (National Pipe Thread) threads offer a tight seal and reliable engagement with compatible pipe fittings.
- ✅ Nominal Dimensions – 1" nominal pipe size with a 3-1/2" overall length, compatible with standard schedule 40 steel pipe systems.
- ✅ Non-Galvanized Surface – Ideal for applications where welding or additional corrosion coatings may be applied.

Installation Notes
To ensure optimal sealing and joint integrity, use appropriate thread sealant or Teflon tape. Installation requires standard pipe wrenches or mechanical threading tools. As black steel is uncoated, it should not be used in potable water systems unless corrosion mitigation is in place.
Typical Use Cases
This fitting is widely used in:
- • Natural gas and propane distribution lines
- • Closed-loop hydronic heating systems
- • Compressed air networks in industrial environments
- • Structural piping and mechanical supports
Note on Compliance
Verify local codes and system requirements before use. Not approved for direct potable water service due to non-galvanized steel surface.
