2-1/2 inch x 1-1/4 inch Black Iron Reducing Coupling Female x Female

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

The 2-1/2 inch x 1-1/4 inch 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.
