accordingly. Call for details.

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. |
