To understand what qualities are most important, we must first answer the questions what is a gasket and how does a gasket work. Gasket is a very broad term. It covers a range of seals made from a variety of materials. Gaskets are used in manufacturing equipment, engines, and many other applications. Their purpose is to prevent any substance from escaping or entering a joining. Gaskets are used in both static and moving parts, and generally must withstand pressure without compromising the seal.

A gasket’s more important quality isn’t universal. It’s really how suitable that particular gasket is for the job at hand. Some gaskets, vibration dampening is critical, while for others being able to endure changing temperatures without compromise is the most important quality. A gasket designed for a static joint in a cool, dry environment won’t function well in moving parts used in a hot or damp environment even it if physically fits the pieces. This is why it is important to source gaskets from a supplier who can provide a diverse range of seals to suit various applications and environments. Many industries also benefit from working with a gasket supplier that can make custom gaskets to fit their unique needs.

Different Gaskets for Different Jobs

When choosing, it is important to ask what is a gasket’s main function in this application? Obviously, to seal a joint, but beyond that is it to keep a liquid in or out? To withstand vibration? To joint moving parts or static ones? What environment does it function in? These questions can help you choose the best material for your gasket. Another way to look at it is to ask what is a gasket’s greatest challenge in this application?

Rubber gaskets can withstand temperature extremes while providing flexible sealing, excellent recovery, effective vibration dampening and good durability. Sponge gaskets are ideal for stopping water, gas and sound. They are often used where moisture or dust is an issue. Metallic gaskets include a soft filler and are used for joining flanges or metal pipes. Polytetrafluorethylene (PTFE) gaskets provide an excellent seal for caustic and acid substances. The question what is a gasket is answered by exploring the function, not the material, of the gasket.

Sometimes a gasket is needed to fit an unusual shape or where it requires specific qualities. In those instances, a custom made gasket is the answer.
