Inquiry (采购产品): EPDM or Viton Gasket We are trying to determine whether an old gasket is EPDM or Viton for replacement, and are wondering how we determine the differences. If you could let me know whether we need to do a chemical test or if there is an easier way to determine which is which, that would be great. **** Hidden Message ***** Ryan White 66201 Company: Water District #1 of Johnson Country KS E-mail: rwhite@waterone.org **** Hidden Message ***** rwhite@waterone.org
