Engineered for superior performance, our Ductile Iron (DI) Universal Adaptor and Coupling provide the ultimate solution for connecting DI to PVC pipes and other pipe materials. Their key features include:
Robust Durability: Manufactured from high-strength ductile iron, these fittings offer exceptional impact and load resistance, far exceeding the capabilities of standard PVC fittings. They are corrosion-resistant, ensuring a long service life even in demanding environments.
Versatile Compatibility: The true "universal" design seamlessly connects pipes of different materials (DI to PVC, CIP, PE) and sizes, while also accommodating minor misalignments and dimensional variations. This eliminates the need for multiple, specialized transition fittings.
Leak-Free Security: Featuring a precision-machined groove for a firm, self-restraining grip and a high-quality EPDM gasket, these couplings guarantee a permanent, pressure-tight seal. This reliable joint integrity prevents separation and protects against water loss or infiltration.
Easy & Cost-Effective Installation: The single-unit, bolted design allows for quick assembly without specialized tools, welding, or flanging. This drastically reduces labor time and installation costs, making it an economical and efficient choice for repairs, tie-ins, and new construction projects.
The Ductile Iron (DI) Universal Adaptor and Coupling are engineered for maximum versatility in a wide range of piping scenarios. Their primary application is creating secure, leak-tight transitions between DI pipes and PVC pipes, effectively bridging the performance characteristics of both materials.
These fittings are indispensable in municipal water and sewer systems for repair, maintenance, and new construction projects. They are perfect for emergency repairs, allowing for the swift replacement of a damaged pipe section with a new DI or PVC pipe without the need for exact matching fittings. Furthermore, they are extensively used in pipeline extensions and tie-ins, seamlessly connecting existing pipelines to new ones, even when material types differ. Their ability to accommodate minor misalignments and absorb some vibration and ground movement makes them an excellent choice for areas with unstable soils or for crossing expansion joints. From industrial process lines to irrigation systems, these universal connectors provide a reliable, cost-effective, and labor-saving solution for virtually any transition or connection challenge.
The Ductile Iron (DI) Universal Adaptor and Coupling are engineered as a superior, all-in-one solution for creating robust and reliable connections in pipeline systems. Specifically designed to bridge different pipe materials, these fittings excel in joining Ductile Iron pipe to PVC, as well as other materials such as steel, HDPE, and concrete. This versatility eliminates the need for multiple, specialized transition fittings, streamlining inventory and installation.
Manufactured from high-grade ductile iron, the product boasts exceptional strength, impact resistance, and durability, far surpassing the performance of standard PVC fittings. Its fundamental design consists of a single, compact housing that incorporates a precision-machined groove to securely grip the pipe's outside diameter. This is complemented by a high-quality, pressure-rated EPDM gasket which ensures a permanent, leak-free seal under varying pressure conditions.
A key feature of this universal coupling is its ability to accommodate minor misalignments, dimensional variations, and even absorb limited ground movement or vibration. The self-restraining groove mechanism prevents joint separation, providing long-term system integrity. Installation is remarkably straightforward and cost-effective. The bolted design allows for quick assembly using standard tools, without the need for welding, flanging, or specialized equipment. This drastically reduces labor time and total installation costs.
Ideal for municipal water and sewer projects, industrial applications, and emergency repairs, the Ductile Iron Universal Adaptor and Coupling offer the perfect blend of rugged durability, exceptional versatility, and installation efficiency for both new construction and rehabilitation projects.
