Which Fitting is the Right One?

Threaded fittings made from different materials have different properties and are better suited for certain applications. Some of the key differences between threaded fittings made from malleable cast iron, stainless steel, and brass are:

Malleable Cast Iron:

Threaded fittings made from malleable cast iron are inexpensive and robust. They are resistant to corrosion and abrasion, making them particularly suitable for outdoor applications or harsh environments. However, they are not resistant to high temperatures and can deform at high temperatures.

Stainless Steel:

Threaded fittings made from stainless steel are more expensive than malleable cast iron fittings but are also more resistant to high temperatures and chemicals. They are ideal for applications in the food and pharmaceutical industries because they are hygienic and food-safe.

Brass:

Threaded fittings made from brass are also inexpensive and robust. They are well resistant to corrosion and abrasion but not to high temperatures. They are best suited for applications in water supply and heating systems.

It is important to note that each type of threaded fitting is suitable for specific applications and media. It is important to use the correct fittings for the application and medium to ensure that the connections are tight and secure and to avoid damage or failure.
