About this item

The B&K 521-004HC is a 3/4-inch black iron pipe cross fitting designed to connect four pipe sections at a single intersection point. As part of the ProLine Series, this fitting is engineered for strength, durability, and performance in a wide range of industrial, mechanical, and fuel system applications.

Made from 150-lb class malleable black iron, this cross is ideal for use in systems transporting lubricants, oils, greases, LP gases, natural gases (e.g., nitrogen, oxygen), steam, and diesel. It is not intended for potable water applications. The female iron pipe (FIP) threaded ends conform to ANSI/ASME B1.20.1 standards, ensuring a secure and leak-resistant connection.

The relative softness of the malleable iron allows for a tight seal, while the robust construction supports pressures up to 500 PSI at 150°F. This makes the 521-004HC a dependable choice for demanding environments where multiple pipe runs must intersect.

Key Features:

  • Material: 150-lb class malleable black iron for industrial-grade strength
  • Connection Type: 3/4-inch FIP (Female Iron Pipe) threaded ends
  • Design: Four-way cross fitting for intersecting pipe systems
  • Pressure Rating: Up to 500 PSI at 150°F
  • Thread Standard: ANSI/ASME B1.20.1 compliant
  • Compliance: Meets ASTM and ASME specifications
  • Seal Integrity: Malleable iron provides a secure, tight seal
  • Finish: Black iron for corrosion resistance in non-potable systems

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
  • Mechanical Systems: Ideal for HVAC and compressed air configurations
  • DIY Projects: Great for custom pipe furniture, shelving, and structural builds
