Features
Read full description

Hydravia CrosRef helps you find a CAST part from a full or partial part number of another manufacturer and explore related codes in either direction. Choose the source and comparison brands, then swap them with one tap. The app contains 26,369 CAST part numbers and cross-references from an approved workbook. Each CAST detail page can show a product name, DIN series, tube diameter, pressure rating, L1 length, dimensions, code variants and technical notes. Save frequently used parts to Favorites. Four catalogs are included: the Russian CAST catalog, the English CAST technical catalog, Rastelli Raccordi and Parker. All four PDFs are available offline. Where an exact source page is identified, the part page opens it directly. Otherwise, you can open the full catalog and search within the PDF. The interface supports Russian and English, as well as light, dark and system appearance. Part search and built-in catalogs work without an internet connection. A code cross-reference does not always confirm full interchangeability. Review the match status and technical notes. Before using a part, check pressure rating, dimensions, profile, seals and design against the manufacturers’ documentation.
