Characteristics Of An Efficient Gasket

A gasket has one basic function -  to create a positive seal between two relatively stationary parts.  The thinnest gasket that will create this seal is the most efficient and will last the longest.  It is also the most economical.  To achieve a "tight joint" that will survive the rigors of service, these nine criteria must be met:

Selecting the Right Gasket Material

Every gasket material available to the industry has certain inherent advantages that should be utilized to extend its range of applications.  Limitations in a material can frequently be partly or wholly eliminated by using reinforcing inserts, combining with other materials, and varying the construction or type of joint the material must seal.  Although mechanical factors are important to the design of the complete joint, primary selection of a gasket material is greatly influenced by two factors:  temperature and type of substance to be contained.
