The 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.
