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
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
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.
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
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
2, excellent corrosion resistance
3, the wide range of temperatures applicable
4, good resistance to compression
6, good anti-swelling properties
7, high pressure
8. excellent sealing durability, long life
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 ℃
