O-rings FEP

These o-rings consisting of a seamless and uniform Teflon®, FEP jacket 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.

Features

• High Chemical Resistance: chemical attack and swelling are the primary causes of o-ring failure. Encapsulated o-rings are virtually chemically inert 
• Outperforms solid PTFE o-rings: encapsulated o-rings match the chemical and temperature resistance of solid PTFE O-Rings. Encapsulated o-rings possess properties of elasticity and recovery which are crucial  in many sealing applications 
• All sizes: available in standard and metric sizes from  .059" cross section x ½" I.D. to virtually unlimited larger sizes 
• Economical: encapsulated o-rings economically and effectively replace Kalrez (FFKM) and other exotic O-Ring compounds. Encapsulated o-rings will decrease downtime and hence increase profitability wherever corrosive fluids and gases cause premature seal failure 
• Wide Temperature Range: encapsulated o-rings withstand breakdown caused by industrial solvents and corrosive materials at elevated temperatures from -60° C to +205° C
• Non Stick Surface: provides easy cleanup of viscous materials
• Low Coefficient of Friction: .2 on metal. Self lubricating surface
• Sanitary: eliminates contamination of fluids by elastomers. Sterilizable and autoclavable
• Low Compression Set:  these o-rings consist of either a solid silicone or Viton core encapsulated in FEP resin (with .010 to .045 wall depending cross section) which meets or exceeds requirements of L-P389A and ASTM-D-2166
• Certificates: FDA compliant, USP Class VI compliant, NSF compliance available for specific application
