Black Iron Fittings

Black Iron Fittings are robust threaded fittings used for gas, oil, and high-pressure systems, offering strength, durability and reliability for mechanical and industrial pipeline installations.

About Black Iron Fittings

Black iron fittings are manufactured from malleable iron and are designed for joining pipework in applications such as gas distribution, oil lines, compressed air and heating systems. They are typically coated in a protective black finish to resist corrosion and are connected using screw threads to create a strong mechanical joint.

These fittings are suitable for both residential and commercial use, particularly where high-pressure or high-temperature capabilities are required. Installation must follow current safety standards and be carried out by competent professionals, especially for gas systems.

Benefits

  • High strength: Suitable for high-pressure and mechanical systems.
  • Heat resistant: Suitable for high-temperature applications such as heating systems.
  • Reliable joint connection: OScrew-threaded design ensures a secure and leak-resistant seal.
  • Durable construction: Resistant to impact and long-term exposure.
  • Wide compatibility: Can be used with steel and black iron pipes.

Applications

  • Natural gas and LPG pipework (where approved).
  • Oil and diesel supply systems.
  • Compressed air and mechanical services.
  • Commercial and industrial heating systems.
  • Plant rooms and boiler houses.

Key Features

  • Made from malleable iron with a black oxide finish.
  • Threads conform to BSP standards (British Standard Pipe).
  • Available in multiple types (elbows, tees, unions, sockets, nipples, plugs, caps, etc.).
  • Suitable for both low and high-pressure applications.
  • Compatible with threaded steel and iron pipe.
  • Can be painted or coated for added corrosion resistance.

Installation & Technical Info

Install using suitable pipe thread sealant or PTFE tape to ensure leak-free joints. Avoid over-tightening to prevent cracking. Where used in gas systems, installation and testing must be carried out by a Gas Safe registered engineer in accordance with BS 6891 and IGEM standards.

Black iron fittings are for internal use only and should not be used in underground installations unless adequately protected. Always check compatibility with intended fluid and temperature/pressure ratings before use.
