Grooved ductile iron pipe fittings 

Grooved ductile iron pipe fittings and flanges are commonly used in rigid pipe systems, above-ground pipe installations, and in tight spaces including subfloors, crawl spaces, trenches, and tunnels. Grooved ductile iron is lighter, stronger, and more durable than cast iron. This resilient iron absorbs vibration, handles stress without breaking, and works with water, diluted acids, alkali solutions, oil-free air, and other chemicals. Grooved fittings combine roll-grooving and two-bolt coupling designs in a reliable joint that resists external forces without special supports or expansion joints. Clamps help maintain secure seals under both positive pressure and vacuum conditions. Grooved ductile iron fittings, flanges, and clamps come in a variety of sizes and shapes.
