FEP PTFE Encapsulated O-Rings

Encapsulated O-Ring with PTFE FEP or FPA Encapsulated o-rings are o-rings consisting of a seamless and uniform PTFE FEP/FPA encapsulation which completely encloses a rubber core material. Elastomer/rubber core materials are a choice of Silicone or Viton. Features: High Chemical Resistance:...

  FEP PTFE Encapsulated O-Rings



Elastomeric, Rubber O-rings suffer from high friction and limited resistance to aggressive chemicals and gas permeation. Solid Teflon O-rings are rigid with no effective memory and high compression set.


SVKS Teflon Encapsulated O-rings combine the resilience and sealing force of an elastomer with the chemical resistance of Teflon. This is accomplished by the use of an elastomeric core of silicone or Viton, with a relatively thin encapsulation of Teflon FEP or PFA polymer. This produces an elastomeric PTFE seal with maximum sealing capability.


FEP Encapsulated O-rings are solvent resistant and chemically inert (except for attack by alkaline metals, fluorine and some halogenated compounds at high temperatures) yet have an elastomeric memory near that of rubber O-rings. FEP polymer, also, has an extremely low coefficient of friction (.1 to .2) and very low permeability to gases, making our Encapsulated O-rings virtually universal seal for use in hostile environments.



Broad Size Range:

Vinyl Dip Molding PVC Dip Molding, Plastic Dip Molding, Dip Moulding Available in standard and metric sizes from .059” cross section x ½” I.D. to virtually unlimited larger sizes.


Outperforms solid PTFE O-Rings:

Vinyl Dip Molding PVC Dip Molding, Plastic Dip Molding, Dip Moulding Our Encapsulated O-rings match the chemical and temperature resistance of solid PTFE O-rings.

Vinyl Dip Molding PVC Dip Molding, Plastic Dip Molding, Dip Moulding Encapsulated O-rings possess properties of elasticity and recovery which are crucial in many sealing applications.

Economical:

Vinyl Dip Molding PVC Dip Molding, Plastic Dip Molding, Dip Moulding Encapsulated O-rings economically, and may effectively, replace exotic compounds wherever corrosive fluids and gases cause premature seal failure.

Non-Stick Surface :

Vinyl Dip Molding PVC Dip Molding, Plastic Dip Molding, Dip Moulding Provides easy cleanup of viscous materials.


Sanitary:

Vinyl Dip Molding PVC Dip Molding, Plastic Dip Molding, Dip Moulding Eliminates contamination of fluids by elastomers. Sterilizable and autoclavable.

Outstanding Chemical Resistance :

Vinyl Dip Molding PVC Dip Molding, Plastic Dip Molding, Dip Moulding Chemical attack,and swelling are primary causes of O-ring failure. Encapsulated O-rings are virtually chemically inert.

Minimum compression set:

Vinyl Dip Molding PVC Dip Molding, Plastic Dip Molding, Dip Moulding Core materials (Silicone or Viton) provide optimum resilience vs. compatibility.
