What Is a Seal Cross Reference Chart?
A seal cross reference chart is a comprehensive reference table that maps different seal part numbers across various manufacturers, models, or product lines. Its primary purpose is to help users identify equivalent or compatible seals from different brands or series, enabling easier substitution without the need for extensive research or trial-and-error testing.
Key features of a seal cross reference chart:
- Manufacturer-specific mappings: Shows equivalent seals across different brands
- Model-specific references: Links seals suitable for various machinery or equipment models
- Material and size details: Provides crucial specifications for proper fit and performance
- Compatibility information: Indicates which seals can be interchanged safely

Components of a Seal Cross Reference Chart
A typical seal cross reference chart includes several critical pieces of information:
1. Original Seal Part Number
The manufacturer’s unique identifier for the seal.
2. Alternative or Cross-Referenced Part Numbers
Equivalent or compatible part numbers from different manufacturers.
3. Seal Dimensions
Details such as inner diameter (ID), outer diameter (OD), and cross-sectional thickness, which are vital for proper fit.
4. Material Specifications
Information about the seal material (e.g., Nitrile, Viton, Silicone), indicating suitability for different fluids and temperatures.
5. Application or Equipment Compatibility
Details about which machinery, pumps, or systems the seal is designed for.
6. Additional Notes or Special Features
Any relevant information like pressure ratings, chemical resistance, or installation tips.
