What are some considerations in varying the base (carrier) for specific applications?
Since requirements such as flange stiffness, bolt loading and internal pressure vary from application to application, Select-a-Seal applications engineers examine the specific characteristics of a joint while choosing a base carrier. For example, a carrier can be selected that optimizes the required physical properties (compression, tensile strength, surface friction, etc.) while taking into consideration specific conditions that the joint may experience (shear forces, low temperatures, etc.). It’s easier to vary the mechanical characteristics of Select-a-Seal base composites than it is to vary the bases of other kinds of gaskets, because in an REC gasket, the edge, not the carrier, forms the seal.
