Malleable Iron Fittings

Malleable iron fittings are popular across multiple trades including electrical, plumbing, and building, and industries as diverse as mining, farming, and manufacturing.

Their valuable combination of high tensile strength and flexibility allows them to resist changes in temperature, movement, stress, shock, and chemical abrasion.

RS’ selection of malleable iron fittings covers a wide range of requirements, including barrel nipples and equal union connectors. A trusted malleable iron fittings manufacturer, our RS Pro by RS range is made to high-quality specifications and can be relied upon to perform efficiently and effectively without the need for maintenance. And with bulk buy deals available, they’re a great choice if you need a large number of fittings for your project.

What are malleable iron fittings?

Malleable iron fittings are metallic fittings formed from white cast iron that has been heated to over 900°C, then slowly cooled. This process, known as annealing, changes the atomic structure of the metal, forming strong lattices of iron mixed with irregularly shaped crystalline carbon nodules that contain fewer imperfections and round edges.

This means the resulting metal can resist shock, movement, thermal expansion, and contraction. These sources of deformation would typically damage a non-malleable iron fitting over time.

These fittings are therefore an excellent choice for industrial and residential applications with low maintenance requirements; malleable iron pipe fittings are an excellent choice for heating systems, for example. They can also be easily machined, and while they can be welded to other metals, the heat can remove the malleable qualities and introduce brittleness, so the resulting effects of this should be fully considered before welding your fittings.

What are the different types of malleable iron fittings?

When selecting malleable iron fittings, there are many to choose from, including elbows, couplings, flanges, barrel nipples, tees, and equal union connectors. There are also some specialized types, such as:

• Malleable iron pipe fittings – Designed to ensure durability along pipelines, such as those transporting oil, chemicals, or water.
• Black malleable iron fittings – These are used within line systems transporting gases, such as natural gas or propane in industrial processes or residential buildings.

The type of malleable iron fitting you require will depend on the job at hand. Browse our range using our advanced filter options to find the correct part.

What are the uses of malleable iron fittings?

Ductile and tough, malleable iron fittings are used in applications that call for high resistance and longevity at both hot and cold temperatures. They are also relatively inexpensive compared to fittings crafted from other metals, affording a good economy.

Malleable iron is typically used to create machined, pierced, cold-formed, and coined fittings – small ones in particular. They are used in the manufacture of vehicles, liquid and airlines, tools, industrial machinery and cooling, lubrication and heating systems,
