There appears to be a number of gasket materials which are similar. How do I choose between them?

It is helpful if some of the basic performance requirements are known, such as: temperature, media being sealed, location of sealing joint, and any specific requirements or call-outs which must be met. Our staff can help you sort through your requirements and provide additional information which will make the selection process easier.

What is a starburst core, and when would I use it?

The starburst core refers to the tang formation created when the metal core is pierced. The result is a column-shaped protrusion which is quite durable. This type of tang is ideally suited to withstand environments which are subject to scrubbing, vibration, or flange movement due to rapid heating cycles or dissimilar metals at the seal point. This core style makes up our HT (Hi-Tex) and AR (Armor) product lines. Starburst core is the preferred choice for hot gas (exhaust) and other heavy duty gasket applications. It provides the radial strength and durability needed for high and extreme applications.

What is Corseal core, and when would I use it?

Corseal is our smaller rectangular tang formation which provides nearly twice the number of bonding points per square inch as our starburst technology. This configuration allows for a softer crush at bolt up and is ideally suited for narrow wall and tight geometric configurations. Corseal technology is industry proven for gaskets such as cylinder head, intake and other lower load applications.

What is Surbond, and when would I use it?

Surbond is our solid core technology, which uses a proprietary adhesive system to bond the facing material to the steel. A solid steel core does not have any holes which could become leak paths, making this style well suited for fluid sealing applications. Surbond is often used in fuel, oil and water pump gaskets, and will service many other applications which are not exposed to higher temperatures.
