The High-Temperature Series seals have successfully sealed
high-temperature fluids in the chemical and hydrocarbon
processing industries for over 30 years. Supplied with GrafoilŪ
secondary packings, the Type 604, 606, and 609 seals are able to
withstand up to 425°C/800°F process temperature without the
need for expensive cooling flushes. Mean-Time-Between-Planned
Maintenance (MTBPM) is extended due to the elimination of
unreliable ancillary support systems.
