What are common materials used for fittings?

Stainless Steel

Stainless steel threaded fittings are highly corrosion-resistant and suitable for a wide range of applications. Different grades of stainless steel (e.g., 304, 316) offer varying levels of corrosion resistance and strength.

Brass

Brass threaded fittings are often chosen for their good corrosion resistance, ease of machining, and relatively low cost. They are commonly used in plumbing and low-pressure applications.

Black Steel (Carbon Steel)

Black steel threaded fittings, also known as carbon steel fittings, are notable for their strength and durability. They are often used in industrial applications where high pressure and temperature conditions are encountered. The term “black steel” refers to the appearance of the material, which is created through a protective coating of oil or paint to prevent rusting.

Bronze

Bronze threaded fittings have good corrosion resistance and are often used in applications involving seawater and other corrosive environments.

Copper

Copper threaded fittings are suitable for applications where corrosion resistance and electrical conductivity are important, such as in plumbing and electrical systems.

PVC (Polyvinyl Chloride)

PVC threaded fittings are used in systems that transport non-corrosive liquids. They are commonly used in water supply, irrigation, and drainage systems.

CPVC (Chlorinated Polyvinyl Chloride)

CPVC threaded fittings offer higher temperature resistance compared to standard PVC fittings. They are used in hot water supply systems.

Cast Iron

Cast iron threaded fittings are durable and used in heavy-duty applications, such as plumbing, industrial systems, and municipal water distribution.

Aluminum

Aluminum threaded fittings are lightweight and corrosion-resistant, making them suitable for certain industrial and lightweight applications.

Nylon and Plastic

Threaded fittings made from nylon or other plastics are used in systems where chemical compatibility, lightweight, and non-corrosive properties are important.

Ductile Iron

Ductile iron threaded fittings combine the strength of cast iron with improved ductility and impact resistance. They are often used in high-pressure applications.
