Featured O-ring Material: Kalrez®

Working with really high temperatures and extremely caustic substances makes Kalrez® o-rings an option when no other o-ring will do the job.  Kalrez®, known to be expensive throughout the marketplace, is an o-ring material that is still worth consideration if your application requires the use of harsh chemicals.  Because Kalrez® works so well in extreme environments, cost can be justified with savings in other areas such as ensuring a device will run smoothly and efficiently because the o-ring seal is capable of resisting particularly rigid substances.  
 
Kalrez® is available in all of our Series 300 Modular Check Valves, as well as Model #150 Standard Cartridge Valve, Model #157 Manual Relief Bleed Valve, and Model #15b Flanged Outlet Valve.  It is important to note that we are not able to offer Kalrez® with a spring lower than 0.5 PSI.   

Kalrez® works especially well with:

• Low Out Gassing
• Chlorine Wet/Dry
• Petroleum Oil
• Chlorinated Hydrocarbons

Temperature ranges for Kalrez® are from -10°F to 615°F. This material is available in 80 or 90 durometer (hardness of the o-ring) sizes.
 
As you will see in the chart below, Kalrez® has a “good” rating for wear, compression set, and permeation resistance.  It is rated “moderate” for short-term resilience.
