Reducer Coupling Reducer, 3" x 2" Pipe, FNPT, Malleable Iron, Class 150

Description

A heavy-duty threaded coupling that provides a reliable transition from a 3″ female NPT connection to a 2″ female NPT connection. Engineered from malleable iron and rated for Class 150 service, this reducer coupling is ideal for piping systems that require dropping pipe size while maintaining pressure ratings.

Benefits & Applications

• Size Reduction: Efficiently connects between 3″ and 2″ female NPT pipes in systems where you step down flow, such as branch lines or pressure adjustments.
• Durable Construction: Malleable iron offers strength, toughness, and good resistance to pressures in plumbing, industrial, or utility piping systems.
• Code-Compliant: Built to meet recognized standards (ASTM, ASME) and certified for many industrial applications.
• Versatile Use: Suitable for water, steam, air, and general piping systems under conditions that do not exceed Class 150 limits.
• Steam Capability: Rated for moderate steam service (saturated) up to the stated limits, making it usable in steam systems where Class 150 is acceptable.

Installation & Usage Tips

1. Thread Sealant Recommended: Use appropriate pipe thread sealant or Teflon tape to ensure leak-free connections — particularly on steam or pressurized lines.
2. Hand-Tighten Then Wrench: Start with hand tightening, then use a wrench to finalize, avoiding excessive torque that could crack the fitting.
3. Verify Alignment: Make sure the mating pipes are properly aligned before tightening fully, to avoid strain or mis-threading.
4. Avoid Overheating or Shock: Though rated for a broad temperature range, avoid exposing the coupling to thermal shock or temperatures beyond specs.
5. Inspect After Installation: Especially in steam or high-temperature use, check periodically for leaks or signs of deterioration (e.g. corrosion, scaling).
