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. Due to this, special attention should be paid to the type of gasket material that is selected for use in the various seal points. What you are sealing, as well as temperature, pressure, flange conditions, and available load are all factors that matter.

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.

Things to Look For

Here is a list of some of the more ideal characteristics of a gasket material used in the exhaust manifold.

1. Heat tolerance

The gasket material should be able to withstand the temperature of the application without oxidizing, burning, or otherwise disintegrating. MTI offers the Hi-Tex line of products for high temperature applications.

2. Conformance

The gasket should compress or conform to flange conditions and irregularities to make a good seal. Is the joint designed for a precision steel gasket, or can a cost savings be found by utilizing a proven, composite style design? MTI’s Hi-Tex line of laminates also performs very well in the exhaust manifold.

3. Flange conditions

Is there thermal motion and scrubbing present? Sometimes gaskets must be very robust to resist or tolerate thermal motion and still maintain a seal. MTI’s Armor products address this issue with metal-clad construction.

Deciding on a Material

Once you understand what is necessary to have in an exhaust manifold gasket, it becomes pretty easy to narrow down your material choices. If you still aren’t sure about the material that will best meet your needs, talk to your trusted gasket material supplier. They should be able to recommend a material that is a known performer in this seal point.
