Vulcan Mechanical Seals - American Coding System

While Vulcan operates its own global Mechanical Seal coding system, it also incorporates common American coding systems for all standard American Mechanical Seals to ensure it maintains the simplicity of business.

Seal numbers follow the standard “PS” American coding system format, as is common in the North American market, except a "VS" prefix is used instead (e.g. VS185 = PS185).


Please use the document downloads, tables and diagrams on this page for guidance.
