O-Ring Material Identifiers, Installation & Extraction Tools

TESTER O-Ring Material Identifier

Global Rubber Products Ltd.’s O-Ring Material Identifier is a handy way to identify the composition of four O-Ring types. The wedge-shaped metal weight slides down the tube and onto the O-Ring. As it bounces up, quickly watch which material range to which it bounces.


This tester identifies:

  • EP - Ethylene Propylene
  • N – Nitrile
  • P - Perfluorolastomer (Kalrez®)
  • F - Fluoroelastomer
