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. 

Chemical Resistance:

Kalrez® O-Rings have virtually universal chemical resistance.  They

will withstand attack by more than 1,800 chemicals including solvents,

acids, bases, and oxidizers.

Thermal Stability:

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.
