M-COR Precision O-Rings


Encapsulated O-Rings

M-COR Precision O-Rings - Encapsulated O-Rings M-COR encapsulated O-rings consist of a seamless and uniform Teflon FEP / PFA encapsulation which completely encloses a core material of either silicone or Viton elastomers. The combination of these components creates an O-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments.

  • Chemical attack and swelling are the primary causes of O-ring failure. M-COR encapsulated O-rings are virtually chemically inert.
  • M-COR encapsulated O-rings match the chemical and temperature resistance of solid PTFE O-rings, M-COR encapsulated O-rings possess properties of elasticity and recovery which are crucial in many sealing applications.
  • M-COR encapsulated O-rings economically and effectively replace Kalrez and other exotic O-ring compounds. M-COR encapsulated O-rings will decrease downtime and hence increase profitability wherever corrosive fluids and gases cause premature seal failure.
  • M-COR encapsulated O-rings withstand breakdown caused by industrial solvents and corrosive materials at elevated temperatures from -60 C / -75 F to +205 C / 400 F.
  • M-COR's encapsulated O-rings have a non Stick surface, allowing for easy cleanup of viscous materials.
  • Low coefficient of friction (.2 on metal).
  • Eliminates contamination of fluids by elastomers. Sterilizable and autoclavable. FDA compliant, USP Class VI compliant, NSF compliance available for specific applications.
  • Available in standard and metric sizes from .059" cross section x " I.D. to virtually unlimited larger sizes.
