Every market has its own set of preferences and needs as it applies to gaskets and the materials they are made from. High-performance applications are no exception. Obviously, everyone needs gaskets that meet the requirements of the application, effectively seal and have value. However, there are some different considerations that you will need to pay attention to if you work or desire to work in high-performance applications.
Below you will find four things that you should be aware of when dealing with gaskets in high-performance applications.
What You Should Know
1. Machining makes a difference in the gaskets used.
This is true in any application, but you do see a wide spectrum of machining in high performance. The time (and money) spent on flange surfaces has a direct correlation with your gasket choice. On rough and uneven flanges, composite materials are the best choice. They can fill in surface imperfections and achieve a seal where other materials will not. Other types of gasket designs require costly machining to achieve the smooth finishes that are necessary.
2. Clean teardown is important.
When you think of high performance, you think of quick and efficient turnovers. Gaskets that come apart cleanly without sticking are desired. What should you look for in gaskets to achieve this? First, an anti-stick coating gives you the ability to remove your gaskets without much scraping or peeling. Second, utilizing “armor” type materials (metal on the outside) provides the same benefit in exhaust applications.
With the clean teardown comes the expectation to reuse a gasket. This is especially true in high-performance applications. While it isn’t recommended to even reuse a gasket, you can get away with it under certain conditions. Review our blog post The Great Gasket Debate: To Reuse or Not To Reuse.
4. Material Quality
Generally, materials used in “high-performance” applications are a better grade than the standard product. It might be a better polymer system, a higher grade of graphite for longer life, an aramid fiber vs a cellulose fiber, etc. Also, gaskets may feature higher density materials for better recovery properties and low creep. A simple change such as using a better base material for a gasket might offer significant benefits to a part and elevate it to “high-performance” status.
Find What Works for You
If you are unsure whether or not a specific material will meet the needs of your high-performance application, don’t hesitate to talk to your trusted gasket material supplier. Identifying the right materials to meet the requirements of your application can sometimes be difficult.

The Great Gasket Debate: To Reuse or Not To Reuse
As an expert resource that knows gasket material inside and out, we’re going to break down some of the arguments for and against reusing, and what you need to consider when making that decision for your application. And maybe…there is a time or two that it really might be ok to reuse one.
What Qualifies as 'High Temperature' When Talking About Gaskets?
If you ask half a dozen application engineers and gasket fabricators what they consider to be ‘high temperature’ in regards to their selection of a gasket material, you’re likely to get a range of answers. You’ll also find that none of them are really wrong, since ‘high temperature’ is a relative term. So, how does one navigate the world of high temperature gasket materials when the terminology is so ambiguous?
6 Ways To Make Life Easier If You Work In High Temp Applications
Once you really understand how to deal with high temperature applications and what you need to know to start the process of selecting the right material for these applications, you’ve won half the battle. Here are a few tips and items of note that will get you moving in the right direction.
The Top 6 Applications Where Composite Gaskets Excel
As an experienced materials manufacturer, when we hear a customer or potential customer start talking about gasketing needs, there are certain applications where we know immediately that metal reinforced composite laminates are a great option. To help you in your planning process, we decided to put together a list of the top applications where these types of gaskets excel (in no particular order).
The Top 5 Things to Remember When Working with Gaskets for Service Applications
Not all gaskets go into brand new applications straight off the production line. There are many gaskets used across the aftermarket, in service operations and in engine rebuilding. Do the same rules and considerations apply to the seal points and gaskets in service applications as they do in OEM manufacturing? We have put together a list of considerations for those working with gaskets in situations where a gasket is being replaced.
