Detailed Product Description:
Specifically sized for Pall’s Megaplast™ In-Line PFA Filter Housings,
when maximum chemical resistance is required, Kalrez® perfluoroelastomer
O-Rings last longer and seal more effectively than any other elastomer
in even the most hostile environments.
Kalrez® O-Rings have virtually universal chemical resistance. They
will withstand attack by more than 1,800 chemicals including solvents,
acids, bases, and oxidizers.
For long-term exposure to temperatures up to 327°F, Kalrez® retains its
elasticity and recovery properties better than other high temperature
elastomers. It resists hardening and embrittlement, the principal heat-
related cause of seal degradation and failure.
Retention of Sealing Force:
As proven in ISO 334 tests, Kalrez® outperforms other elastomers
when it comes to sealing force retention, a measure of seal life. Even
under harsh and aggressive conditions, Kalrez® will retain its sealing
force longer in both short and long-term service. And due to its true
rubber resiliency, Kalrez® prevents leaks caused by creep, a major
problem with PTFE and other plastic materials.
Kalrez® parts also exhibit low compression set, maintaining their elastic
recovery to maintain tight seals over the long haul. Because Kalrez®
parts recover better under compression than other perfluoroelastomers,
they maintain their shape better under prolonged stress.
These rings are fabricated of DuPont Kalrez type 6375.
