What Materials Are Commonly Used for Making Custom Gaskets?

When considering custom gaskets, you need to match the correct material to the application to achieve maximum performance.Gaskets typically seal the connection betweentwo mechanical parts, such as two lengths of pipe, to typically seal in liquids or gases.  Custom gaskets come in nearly any shape imaginable, in sizes as small as a dime, or smaller, and as large as an SUV, or larger, and are be made from many different materials, depending on one’s application.

How do you know what material is best for your gasket application?  A good approach is to speak with the engineers at a gasket cutting service.  ThePrecision Cutting Service teamis always happy to provide guidancefor gasket materials and their uses.

Common Custom Gasket Materials and Their Usage

  1. Rubber (aka Elastomeric materials)

Rubber and various other elastomeric materials are probably the most common choice for gaskets, because most forms of rubber—both natural and artificial—are inexpensive, while still offering great impermeability.  Rubber, however, is not perfect.  Many variations react poorly to high heat, and various formulations are often susceptible to acids, bases, or even sunlight.

That said, with the wide range of elastomeric materials on the market today, you can usually find a rubber solution that will meet your gasket needs. Fluoroelastomer, for example, has strong acid resistance but is weak against heat.  Neoprene is the opposite.  Let the experts at Precision Cutting Service help you find the best material for your application.

  1. Compressed Fiber

Another popular gasket materialis compressed fiber, especially C4401, which is a good replacement for Asbestos. Compressed fiber gaskets are generally more resistant to heat than rubber, but, unlike rubber, they also tend to vibrate under stress.  In certain applications, this can weaken their effectiveness.

  1. Cork

Cork is widely used for gaskets. It’s high flexibility and resilience allow it to be substantially compressed, and it’s also quite resistant to oil and other substances that can compromise the integrity of rubber or compressed fiber.  Plus, cork is extremely affordable and easy to cut.
