What is a gasket? A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. They allow for “less-than-perfect” mating surfaces on machine parts where they can fill irregularities. Given the potential cost and safety implications of faulty or leaking gaskets, it is critical that the correct gasket material is selected to fit the needs of the application.

Seal & Design can help with expert staff and a broad wide variety of gasketing products and gasket solutions. We fabricate hundreds of materials in different material styles. Capabilities include: Die cut, Water-jet cut, Beaded Gaskets, Pressure Sensitive Adhesive (PSA) laminated parts, Prototyping, Kiss Cut, custom packaging and kitting, and engineering assistance. 

InfoSeal & Design can work with customers’ specifications to develop specific tools and dies to fabricate custom gaskets with a high degree of precision and repeatability.




As an added service, Seal & Design offers technical support for any application where you are uncertain about which gasket material to use. Phone or e-mail us, and we will be pleased to make a recommendation.

Beater-addition gasket materials, or simply Beater Add for short, are made by proprietary manufacturing processes. Each Beater Add vendor has their own process but the general process is as follows: A select mixture of water, latex, fibers, fillers, and chemicals is formed into a slurry. The slurry is then run through specialized machinery that extracts the water, dries the mixture, compresses, and vulcanizes the material into a long continuous sheet.

Metallic Gaskets are used for sealing higher temperature and pressure applications, where non-asbestos materials will fail. Typical applications are for heat exchangers, compressors, condensers, pumps, and valves.

Grafoil flexible graphite is a superior performing packing and gasket material. It is the first fluid sealing material made exclusively from natural graphite flake. As a result, its resistance to corrosion, aggressive chemicals, heat and fire make it a critical sealing solution for a variety of applications. 

Its high degree of chemical compatibility makes Grafoil inert to most chemicals and gases. It provides an excellent seal even after continuous exposure to the elements.

Viton® gaskets have excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals.

We sell rubber gasketing material in sheets, rolls, or fabricated to specs. Our knowledgeable sales staff will provide you with fast, personal service. Elastomeric rubber compounds can be used for both o-rings and gasketing products.

Sponge gaskets vary widely in material composition and thickness. Typical applications include packaging and vibration reduction solutions for the transportation industry.

Foam gaskets vary widely in material composition and thickness. Typical applications include vibration reduction solutions for the transportation industry and noise reduction products.

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is also known by the common trade name TEFLON™, trademark owned by The Chemours Company. PTFE can be modified for use as a gasketing material with strong chemical resistance properties.
