Teflon is generally unaffected by fuels and most products. It has a wide temp range and when there is a properly designed seal/seat arrangement, it will seal well in a PV vent application. It is more resistant to the seat freezing in cold weather. Not being an elastomer, it is not as flexible as an elastomer, such as Viton.
Encapsulated o-rings are o-rings consisting of a seamless and uniform PTFE encapsulation which completely encloses a rubber core material. Elastomer/rubber core material are a choice of Silicone or FKM. The …

Ventajas y desventajas del vitón. El vitón o caucho fluorado es resistente a una amplia gama de aceites minerales e incluso a un gran número de aditivos presentes en los aceites. Sin embargo, ciertas aminas que se encuentran en …
PTFE is a synthetic polymer derived from chemical bonding between carbon and fluorine, taking advantage of free radicals' tendency to polymerize with tetrafluoroethylene. This material was accidentally discovered in 1938, when DuPont chemist Roy J. Plunkett attempted to create a new type of refrigerant, and mixed these materials together ...

PTFE = Polytetrafluorethylen für O-Ringe in den Einsatzbereichen zwischen - 200°C bis 260°C. Die Gleiteigenschaften von PTFE sind die besten aller Kunststoffe. Statischer und dynamischer Reibungskoeffizient sind gleich, was das Material zu einem stick-slip freien Gleitwerkstoff macht. Handelsnamen für O-Ringe aus PTFE: z.B. Dyneon ...
Spring Energized Teflon Seals provide the best chemical resistance, widest temperature and pressure performance ranges of any plastic or elastomeric seal. Spring Energized Teflon Seals can perform in Cryogenic Sealing temperatures of nearly absolute zero -420 o F to 600 o F. Pressures up to 3,000 psi and custom designs allow up to 60,000 psi.
Applications of Viton® O-ring. The fluorcarbon Viton® O-ring can be used in mechinical devices such as aircrafts and automobiles, which require maximum resistance to high temperatures and several different fluids such as oils and fuels. It is suitable for high vacuum applications, because the Viton® O-ring has a high shrinking rate.

Virtually Chemically Inert. PTFE Encapsulated Viton® o-rings are o-rings consisting of a seamless and uniform PTFE FEP/PFA encapsulation/jacket which completely encloses a core material Viton® fluoroelastomer (also available in silicone). The combination of these components creates an o-ring that is virtually chemically inert and compression set resistant for use in harsh …
Optimal Viton Temperature Ranges. For general-type seals, the optimal viton o-ring temperature range is between -15°F and 450°F in static applications, though it can withstand service temperatures up to 527°F for a short time. Full operation at 450°F will shorten parts' lifetime more than full operation at -15°F.

Viton vs Teflon (PTFE) - Viton offers a greater temperature resistance but falls short of Teflons (PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties. And lastly due to the rigidness of the plastic on teflon, Viton offers a much more capable sealing ability.
Teflon O-Rings,Polytetrafluoroethylene (PTFE) is used wherever the chemical and thermal resistance of the elastomer O-Rings is no longer sufficient. These are primarily applications in the chemical, food, pharmaceuticals and medical …

The full ones have all carbon atoms surrounded by fluorine and the partial ones have some besides fluorine. PTFE is the original DuPont Teflon fully fluorinated material. PFA is basically also pure Teflon but is injection moldable. Viton and EPDM are partially fluorinated elastomers but much less expensive than PTFE.
Viton® temperature rating Depending on the grade the working temperature range is considered to be -26°C to +205°/230°C (-15°F to +400°/440°F). But for short working periods it will take even higher temperatures.
