Select the Right Component for the Job

We understand that quality is key for strong, reliable and long-lasting piping infrastructure and provide fittings and nipples with excellent mechanical strength, durability and temperature resistance. Our comprehensive selection of industrial pipe fittings and nipples includes various iron types to match your application specs, including:

• Malleable iron: Malleable iron fittings for sale are heat-treated, providing superior durability and vibration resistance for industrial machinery and systems.
• Black iron: This type is uncoated malleable iron and is best suited to create strong and seamless piping in natural gas, propane and oil supply line applications.
• Galvanized iron: These components are malleable iron coated in a layer of zinc to prevent rust. This coating makes them ideal for water, drainage and outdoor applications.
• Cast iron: This iron type is a strong, versatile alloy that provides excellent heat retention, used for low-pressure applications like drainage, waste and vent (DWV).

Find Your Required Size, Schedule and Type

Matching the correct fitting schedule to your pipe system's pressure requirements is crucial for a safe, reliable and durable system design. It ensures the pipe wall will be strong enough to handle the forces for its application during its service life.

Our fittings feature standard National Pipe Taper (NPT) threads with a 60° angle and a gradual diameter decrease. These features help ensure secure connections with leak-tight seals in piping systems. You can use the filters on our product page to sort options by diameter, material and fitting or contact our team online for support to find the right component for you.
