Manway Gasket -Find your Seals Aftermarket - MATCH BY SIZE

HD Process supplies hygienic manway seals and tank gaskets grouped by diameter, helping you quickly narrow down the correct replacement seal for your tank or process vessel. Sorting by diameter is often the fastest starting point before confirming the seal profile, material and compatibility with the existing manway design.

We can assist with seal identification for common inward-opening, outward-opening and pressure manways. Final selection should consider the measured diameter, cross-section profile and elastomer compatibility with the product, cleaning chemicals and operating temperature.

Find Manway Seals by Diameter

• Manway seals grouped by measured mid-range diameter
• Standard diameters to suit common stainless steel tank manways
• Quick identification of potential replacement gasket sizes
• Support for confirming dimensions from drawings, measurements or photos

Manway Gasket Materials and Seal Profiles

• Food-grade elastomer options including EPDM, silicone, NBR and Viton
• Material selection based on temperature, product and chemical exposure
• Cross-section and profile matching to suit the existing manway design
• Replacement options for common OEM and aftermarket manway seals

Confirming the Correct Replacement Seal

Diameter alone may not confirm compatibility because seals with similar overall dimensions can have different profiles or mounting arrangements. Check the existing seal diameter and cross-section wherever possible, or send HD Process a clear photo and measurements for assistance identifying the correct option.
