About this item

The B&K 521-005HC is a 1-inch black iron cross fitting from the ProLine Series, designed to provide a secure and durable four-way connection in piping systems. This fitting is ideal for applications where two piping systems intersect and require a robust, leak-resistant junction. Constructed from 150-lb class malleable iron, this cross is engineered for strength and long-term performance in demanding environments.

The black finish offers corrosion resistance in non-potable systems, while the female iron pipe (FIP) threaded ends ensure compatibility with standard pipe fittings. This fitting is not intended for potable water use but is well-suited for a wide range of industrial and mechanical applications.

Key Features:

  • Material: 150-lb class malleable black iron for industrial-grade strength
  • Finish: Black coating for corrosion resistance in non-potable systems
  • Connection Type: Four 1" FIP (Female Iron Pipe) threaded ends
  • Design: Cross fitting for intersecting pipe systems
  • 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
  • Packaging: Available in case quantities of 15 units

Applications:

  • Fuel Systems: Suitable for LP gas and natural gas distribution
  • Industrial Piping: Used in systems transporting lubricants, oils, greases, and diesel
  • Steam Lines: Compatible with low-pressure steam applications
  • Compressed Air Systems: Provides reliable connections in pneumatic systems
  • DIY & Fabrication Projects: Ideal for custom pipe furniture, shelving, and structural builds
