About this item

The B&K 521-963HN is a 1-1/4-inch Male Iron Pipe (MIP) x 1/2-inch Female Iron Pipe (FIP) black iron hex bushing, designed to reduce pipe size in non-potable fluid and gas systems. As part of the ProLine Series, this fitting is engineered for strength, reliability, and long-term performance in industrial, mechanical, and fuel system applications.

Constructed from 150-lb class malleable iron, this hex bushing features a black finish for corrosion resistance and is not intended for potable water use. The hexagonal shape allows for easy installation with a wrench, and the threaded ends comply with ANSI/ASME B1.20.1 standards for secure, leak-resistant connections.

Rated for up to 500 PSI at 150°F, the 521-963HN is ideal for systems transporting lubricants, oils, greases, LP gases, natural gases (e.g., nitrogen, oxygen), steam, and diesel.

Key Features:

  • Material: Malleable black iron for industrial-grade strength
  • Finish: Black coating for corrosion resistance in non-potable systems
  • Connection Type: 1-1/4" MIP x 1/2" FIP threaded ends
  • Design: Hex bushing for reducing pipe size with easy wrench installation
  • Seal Integrity: Relative softness of malleable iron ensures a tight, secure seal
  • Thread Standard: ANSI/ASME B1.20.1 compliant
  • Pressure Rating: Up to 500 PSI at 150°F
  • Compliance: Meets ASTM and ASME standards
  • Use Environment: Suitable for indoor and outdoor applications
