Product Description
Encapsulated o-rings are o-rings consisting of a seamless and uniform Teflon® FEP/PFA encapsulation/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.
Economical: Encapsulated o-rings economically and effectively replace Kalrez 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/-75° F to +205° C/400° F. (See General Specifications)
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. FDA compliant, USP Class VI compliant, compliance available for specific applications.
Unlimited Sizes: Available in standard and metric sizes from. 059" cross section X ½ " I. D. To virtually unlimited larger sizes.
Low Compression Set: Encapsulated o-rings consist of either a solid silicone or Viton® Core encapsulated in Teflon® * FEP/PFA resin (with. 010 to. 045 wall depending cross section) which meets or exceeds requirements of L-P389A and ASTM-D-2166. (see technical bulletin)
