Rubber gaskets are mechanical seals placed between the mating surfaces of components to prevent process fluids from escaping or contaminants from entering the system.
While the terms “gasket” and “seal” are often used interchangeably, they are distinct products. Seals are a broad product category that encompasses a wide range of sealing components, including gaskets. While other seals can be used in static or dynamic applications with flat or rounded components, gaskets are generally only used for static applications involving flat flanges.
Gaskets are available in several designs, varying in size, shape, and material, to suit different needs. The three most commonly employed types are:
- Chloroprene gaskets. Chloroprene—better known by its brand name, Neoprene®—is the first synthetic rubber developed. It is extremely durable and highly versatile, enabling gaskets made out of it to withstand harsh environmental conditions (such as sunlight and extreme temperatures) and resist damage from oils and other petroleum solvents.
- EPDM gaskets. Ethylene propylene diene monomer (EPDM) rubber is highly durable and extremely resistant to sunlight and heat. As gaskets manufactured from it are able to withstand harsh weather conditions without losing their structural integrity or color, they are often used in outdoor environments.
- Silicone gaskets. Silicone is a high-performance rubber often used to produce gaskets that are exposed to extremely high or low temperatures. It can remain flexible at temperatures as low as -75° F, a quality that makes it ideal for applications in extreme southern or northern locations.

Industrial Cutting and Forming Techniques for Rubber Gaskets
Once we identify what rubber to use, we employ a variety of cutting and forming techniques to produce the gasket. The methods we use include:
Hand cutting operations are generally used to make prototypes to test out different gasket designs and produce production-quality gaskets for use in less critical applications. Equipped with years of gasket cutting experience, our craftsman can create specialized items for highly unique applications, as well as bond rubber and other materials to metal, fabricate sleeves, and process difficult-to-cut gasketing materials.
Die cutting operations enable us to produce gaskets that are custom-tailored to a specific application. Using a wide range of gasket cutting equipment, we manufacture small to large quantities of gaskets to exact specifications.
Strip cutting operations involve cutting rubber and other materials from sheet or roll goods into sizes based on the customer specifications. We employ a zinc strip cutting table to process a broad selection of materials, including rubber, non-asbestos, neoprene sponge, silicone sponge, Poron, Viton®, vegetable fiber, and more.
Molding and extrusion operations allow us to produce custom precision gaskets in high volumes. The process is ideal for critical applications that require unique rubber extrusions and rubber molded parts.
