Chemical resistance information
(couplings/KAMLOK/gaskets) 　

Chemical resistance information is created based on immersion tests of press sheets and references for the flow passages (inner surfaces) of couplings, and is not data for actual product use. When using chemicals, we ask that users check usability for the actual devices and usage conditions before use.

* Chemical resistance information may change due to changes in product specifications or new information.

Reference operating pressure range 　

Temperature condition: 23°C
Gasket: Reference operating pressure range when using Buna-N (NBR)

* Contact Toyox for information on other gasket materials.
