Kalsi Seal Material Options
Standard Elastomeric Materials*
</table border=”1px”>*For elastomer selection considerations, see the Kalsi Seals Handbook.
Special Purpose / Special Order Seal Materials†† The molding shrink rates of the FKM and TFEP materials differ from the shrink rate of the standard seal materials, and shaft and groove dimensions may require adjustment accordingly. Call for details.
HNBR Material Combinations for Dual Durometer Seals
FEPM/FKM Material Combinations for Composite High Temperature SealsThe molding shrink rate of certain composite high temperature material combinations differs from the shrink rate of the standard seal materials. Shaft and groove dimensions may require adjustment if the seals are made from tooling that is based on the shrink rate of typical HNBR seal materials, particularly with larger seal diameters. Due to shrink rate and lubrication considerations, it is recommended that dedicated tooling should be used for High Temperature Seals. Call for additional information.
