Ductile Iron Pipe Gaskets & Joints

Ductile iron pipe has a wider variety of joints available than any other piping material, giving it greater versatility and flexibility in pipeline design and installation to accommodate various applications. These joints are time proven to be strong, dependable, and bottle-tight.

Both push-on joints and mechanical joints are used with Ductile iron pipe installation. Push-on joints are comprised of a special bell with an internal groove, a plain end, and rubber gasket which is seated into the bell’s groove. This joint forms a watertight seal.

Mechanical joints most typically are used for Ductile iron pipe fittings and have four parts.

1. A flange cast with the bell;
2. A rubber gasket that fits into the bell recess;
3. A gland, or follower ring; and
4. Tee head nuts and bolts for tightening
