FEP encapsulated O-Ring with VIton or Silicone

All-inclusive fluoride plastic O-ring fluorine plastic as a cladding material, rubber O-rings and O-ring as an

elastic spring core manufacturing all standard and non-standard series Series O-ring. The product is the use

of special high temperature fluorine rubber and plastics, a special process composite made of seal products, it has a rubber O-ring has a low compression set properties, but also has a fluorine resin specific heat, cold,

oil, abrasion, weathering resistance, chemical corrosion. Fan can be widely used in various static and dynamic seal occasions, it can replace all conventional rubber O-ring.

All-inclusive fluoride plastic O-rings are widely used in aerospace, automotive, chemical, petrochemical,

chemical, pharmaceutical industry, medical equipment, food industry, biotechnology, clean water, machinery industry, sewage treatment.

Perfluoro O-ring perfluoroelastomer seals capability more than 1600 kinds

Chemical corrosion, temperature up to 315 , called Kalrez, Japan's Daikin Corporation and the former Soviet Union also developed such products, the rubber has a PTFE heat resistance, chemical stability, the ability of the fluorine solvent everything other than the solvent, the Kalrez seal products processed long-term use at 260-290 . Intermittent use

temperature can reach 315 . It is currently the best thermal performance fluorine rubber.

Coated cam lock fittings for rectangle ring, suitable for almost all chemical media, even in the harshest corrosive environments can also be used.

Excellent chemical resistance: FEP / PFA almost all industrial chemicals and solvents are chemically inert, even under high temperature and pressure conditions as well.

Wide temperature range:

FEP package silicon continuous use temperature range: from -75 degrees Fahrenheit (-60 ° C) to +400 degrees F (+ 205 ° C)

FEP package fluorine continuous use temperature range: from -15 degrees Fahrenheit (-26 ° C) to +400 degrees F (+ 205 ° C)

Low friction coefficient: smooth FEP / PFA easier to insert the gasket surface.

Non-stick surface: almost all substances are easy to loose off, easy to clean.

Universal Seal: it can be used to handle almost all the liquid.

Cleaning of: eliminating pollution associated with spring washers.

Available at both ends "open" or "closed" coated strip.

PFA (perfluoroalkoxy)

The upper temperature limit: 500 ° F (260 ° C)

Excellent resistance to heat and chemical resistance

FEP has a relatively stronger resistance to cracking and resistance

Very smooth surface

Low vapor permeability

FDA compliant


General Temperature range: -15 degrees F to +400 degrees Fahrenheit (-26 ° C to + 205 ° C)

Low compression set at high temperatures

Good resistance to ozone, weathering, aging resistance

High heat resistance

It can be used for a wide range of oils or solvents such as: aliphatic, aromatic or halogenated hydrocarbons, and vegetable oils


FEP coated Viton O-ring rubber elasticity and tightness and Teflon chemical resistance combined with organic, which consists of a silicone or Viton core and relatively thin colored plastic Teflon FEP or Teflon PFA overcoat combination, the rubber Teflon seal has excellent sealing performance.

Rubber O-ring wear, chemical resistance and anti-poor gas permeability, pure Telfon O-ring high hardness resistant to compression but less flexible.

Covered with Teflon FEP / Teflon PFA O-ring has a good anti-swelling properties and chemical stability (unless by alkali metals, fluorine and some of the halide erosion at high temperatures) in the vicinity of the rubber O-ring has good elasticity , Telfon FEP / Teflon PFA friction coefficient is very small (only 0.1 to 0.2), and has excellent gas permeation resistance, these properties make FEP coated Viton O-ring can really use in harsh environments.

The main advantages are:

1, outstanding chemical resistance, suitable for almost all chemical media

2, excellent corrosion resistance

3, the wide range of temperatures applicable

4, good resistance to compression

5, anti-friction

6, good anti-swelling properties

7, high pressure

8. excellent sealing durability, long life

Temperature range

Teflon FEP housing: -60 ℃ ~ 180 ℃ can use a short time at high temperature 200 ℃

Teflon PFA housing: -60 ℃ ~ 230 ℃ can use a short time at high temperature 250 ℃
