Thanks for the info link, the kit comes with spares and they don't look like standard (compound) o rings but most likely in the near future I'll need to replace them.If the syringes use standard o-rings on the plunger, get epdm orings off eBay out of Europe. I paid 4-6 bucks with postage for a half dozen. EPDM is dot fluid safe.
