2-1/2" x 1-1/4" Black Malleable Iron Reducing Coupling – Built for Secure Transitions

The 2-1/2" x 1-1/4" Black Malleable Iron Reducing Coupling is engineered for professionals who require reliable pipe transitions between varying diameters. Manufactured to meet ASTM and ANSI standards, this fitting ensures a durable connection for low- to medium-pressure systems where strength and compatibility are essential.

Performance Advantages

  • Material: Constructed from Class 150 black malleable iron, offering high tensile strength and impact resistance.
  • Threading: Tapered NPT (National Pipe Thread) threads per ANSI B1.20.1 for secure, leak-resistant connections.
  • Finish: Uncoated black finish suited for non-potable applications such as air, gas, and steam lines.
  • Operating Pressure: Rated for use in pressure systems up to 150 PSI, depending on temperature and fluid type.

Applications

This reducing coupling is commonly installed in:

  • • Commercial HVAC and gas distribution networks
  • • Industrial piping systems
  • • Mechanical piping for air or oil service
  • • Maintenance and retrofit applications where resizing is required

Installation Guidelines

For optimal performance, apply pipe thread sealant or PTFE tape to male threads prior to installation. Tighten with a compatible wrench using standard torque practices to avoid over-threading or cracking. Always inspect threads for damage before use.

Key Specifications
