Vulcan Seals

United States

While Vulcan operates its own global Mechanical Seal coding system, we also incorporate common American coding systems for all standard American Mechanical Seals to ensure we maintain simplicity of business. For order enquiries, simply advise of your requirements using common American part and material codes. Vulcan Seal Numbers follow the same standard "PS" number format, as is common in the North American market, except a "VS" prefix is used instead (e.g. VS185 = PS185).
