The Best Sheet & Die-Cut Gaskets

Understanding Gasket Types

• Sheet Gaskets: These are large sheets of gasket material that are cut to size on-site or by a gasket fabrication service. They are ideal for creating custom-shaped gaskets or for applications where a large number of gaskets are needed from a single material. Common materials include rubber, cork, PTFE, and compressed non-asbestos fiber (CNAF).
• Die-Cut Gaskets: These are pre-formed gaskets cut precisely using a die, ensuring consistent dimensions and shapes. They are convenient for standard flange sizes and specific equipment, offering a ready-to-use solution. Die-cutting allows for intricate designs and tight tolerances.

Key Material Considerations

• Chemical Resistance: The gasket material must be compatible with the fluids or gases it will encounter to prevent degradation.
• Temperature Range: Ensure the material can withstand the operating temperatures without becoming brittle or deforming.
• Pressure Rating: The gasket needs to handle the system's operating pressure without failing or extruding.
• Flexibility and Compressibility: Some applications require a gasket that can conform to irregular surfaces, while others need a more rigid material.

Installation and Maintenance

• Always ensure flange surfaces are clean and free of debris before installing a gasket.
• Tighten bolts evenly and in a star pattern to ensure uniform compression of the gasket.
• Regularly inspect seals for signs of wear, cracking, or leakage and replace as needed.
