Understanding How Gaskets Work

Understanding how gaskets and seals work is the backbone to any engineered part
at Magnum Diesel Parts, Inc. The load-bearing and environmental properties of a
gasket, or elastomeric seal is given careful consideration during the design process
in order to assure a robust, long-lived sealed assembly. Due to the wide variety of
sealing conditions encountered in the Diesel Industry, it is necessary to be able to
provide gasket and sealing materials with varying physical properties to meet these
individual demands.
With an extensive background in sealing systems and the Diesel Industry, Engineers
at Magnum choose from the highest grade gasket materials and Polymers for sealing
today’s diesel engines. Domestic Polymer compounds for Fluoroelastomers, HNBR,
and used oil resistant Silicones have become common choices with Magnum to seal
the most demanding applications. Experience in the compounding, molding and
curing of these elastomers is what makes the difference in Magnum Diesel sealing
products.

Magnum Selects the Right Materials

In product development, careful consideration is given to the sealing environment
for each application throughout the material selection process. The gasket materials
and sealing compounds are selected based on the specific material properties
required to meet the critical sealing requirements of the assembly.

These properties include:
Compressibility,
Recovery,
Low Creep Relaxation,
Tensile Strength,
Compression Set,
and Chemical Compatibility, just to name a few.
