exhaustHot, Hot, HOT!! If you’re well-versed in combustion engines, you likely associate exhaust systems with extreme heat. If you’re also well-versed in gasket materials and how they perform in heat, you likely know that it takes a special material to withstand the conditions present in an exhaust system.

If you aren’t sure about what to look for in an exhaust gasket material, read on to learn how to identify a material that will survive in the exhaust environment.

Ideal Exhaust Gasket Material Characteristics

The harsh environments of exhaust systems can present a challenge if you don’t use acceptable gasket materials. Finding something to withstand the hot gases requires materials specifically designed to survive such conditions. What characteristics should you look for when selecting a gasket material?

1. Metal reinforcement

This provides strength and durability to maintain position in the face of the extreme conditions.

2. Heat-tolerant facing material

Facing material must withstand heat of exhaust without disintegration over the life of the seal. Materials behave differently over time, be sure to choose what is best for you.

3. Abrasion resistance

This might be a factor in joints with high thermal motion, such as joints of dissimilar metals that expand and contract at different rates. In these cases, often a clad-style material is chosen. MTI offers the AR 400 for situations such as this.

4. Low creep relaxation

Graphite products are a good example of a facing with low creep relaxation. This means it will not continue to lose thickness with the heat and time exposure, thus maintaining good flange loading to maintain the seal.

Making Your Decision

As we’ve said before, there is no one perfect gasket material out there for any application. There are a handful of materials that will meet the requirements of an application and it is up to you to decide which one performs best. In order to better educate yourself, you may need to talk to your trusted gasket material supplier and see what they say about a specific material and how it performs in applications similar to yours.

3 Things You Should Look for When Selecting a Gasket to go from Cylinder Head to Exhaust Manifold
Every seal point is unique in its gasketing needs. Exhaust manifold gaskets are no exception. Having an understanding of the conditions that this gasket is exposed to makes it much easier to decide on a gasket material. In the absence of you knowing exhaust manifolds inside and out, we are happy to get you pointed in the right direction.
What Is Creep Relaxation, and Why Do I Care?
This week we’re going to talk about creep relaxation in gaskets and gasket material. This is something that will happen to some extent in most gasket materials. How much or how little of this you see depends on your gasket material selection and the application itself. It is important to have an understanding of creep relaxation and how it relates to a particular material.
Exhaust Leak? Here Are Some Things To Investigate.
When you’re dealing with an exhaust leak, the issue could be a number of things, and it isn’t necessarily the fault of your gasket or gasket material. Keep on reading for things to investigate during your troubleshooting.
3 Things You Need to Consider When Deciding on EGR Gasket Material
EGR (exhaust gas recirculation) valves serve a specific purpose in engines. They recirculate exhaust gases from the exhaust stream, sending some back into the engine to be burned again. If you are involved with making the decision on EGR gasket material, there are 3 main items of consideration.
Armor (AR)
The Metal Tech Armor series of products consist of perforated metal outer layers applied mechanically to one or both sides of a compressible center layer material. Available with carbon or stainless steel, the high strength steel outer layer protects the inner sealing layer for long term performance...
