Ductile Iron Pipe Fittings

Ductile Iron Pipe Fittings

Also known as ductile cast iron and nodular cast iron, these ductile iron fittings are more impact- and fatigue-resistant than cast iron and PVC fittings. The addition of graphite in ductile iron pipe fittings improves the material's strength and durability. These fittings are commonly used to connect pipe in sewer lines and some water systems.

90° Elbows

Use 90° elbow fittings to make a sharp, perpendicular change in the direction of flow in your system where a small loss of flow pressure is not a problem. They have two female ends to connect to male pipe ends or fittings.

45° Elbows

Add a 45° elbow fitting to your pipe ends for a more gradual flow direction change in your system than with a 90° elbow fitting. These fittings also restrict pipe flow less than 90° elbows and have two female ends for connection to male pipe ends and fittings.

Tees

Combine, change, or divide the flow of materials through pipes with the same diameter using these equal tee fittings. The middle port is set at a 90° angle to the connections on either end. They have three female ports that accept male pipe ends and fittings.

Couplings

Join pipes of the same diameter with couplings to create longer pipe or extend your pipe run. Slide the coupling on a pipe end and tighten the nuts on each side to create a secure connection. They feature two female ends for connecting with two male pipe ends or fittings.

AWWA Couplings

These couplings meet AWWA (American Water Works Association) specification C219 for water pipe systems, which provides guidelines on fitting dimensions, materials, testing, and inspection. These couplings are adjustable to join pipe of the same or slightly different diameters together to create longer lengths of pipe. They can also be used when replacing split or heavily damaged pipes. Slide the coupling on a pipe end and tighten the nuts on each side to create a secure connection.

Side-Install Couplings

Quicker to install than standard couplings, these rigid couplings are installed by loosening the nuts and bolts on their sides and sliding the coupling over compatible pipes with grooved ends. Once the pipe ends are lined up, center the coupling over the pipe ends and tighten the nuts for a secure fit. They have a self-centering joint and a gasket to keep a tight seal in pressure and vacuum applications.

Reducing Couplings

Connect pipe with a larger diameter to a pipe with a smaller diameter to reduce the size of the pipeline using these reducing couplings. They have two female ends for connecting with two male pipe ends or fittings.

Unions

Unscrew the hex-shaped nut on these union fittings with a standard wrench to install, remove, clean, or maintain pipe sections with less disruption to your system than threaded fittings that require full pipe rotation to remove. They have two female-threaded ends for connection to male-threaded pipe ends and fittings.

Caps

Stop or direct the flow of material in your pipe system using these caps. Install them on the outside of a pipe end.
