Features:
The organic combination of PTFE double coated PTFE coated O type sealing ring ring by / Silicone and FEP / PFA two rubber materials, with conventional aprons and pure PTFE O type sealing ring There is nothing comparable to this and long life, especially in the harsh medium. Material and use temperature range: shell: PTFE FEP (FEP) -60 ~205 DEG C at 260 Deg. C for a short time using PFA shell: PTFE (poly perfluoro alkoxy) -60 ~260 DEG C at 300 Deg. C for a short period of time using the core: fluorine rubber E-60C core: Silicon silicone rubber ZZR 765B advantages: chemical resistance of L outstanding, suitable for almost all l chemical medium corrosion is excellent l wide temperature range l withstand performance l l good anti friction anti swelling l high voltage l with excellent sealing durability, long service life.

Advantage:
Compare with other O-rings: higher pressure, better flexibility, easier to install etc.
1. Resistance and extremely versatile, suitable for almost all chemical media under normal use, PTFE only by a few small chemical erosion.
2. Applicable to a wide temperature range of -60 ℃ ~ 260 ℃, can be used in a short time high temperature 300 ℃.
3. Good compression resistance PTFE outer coating makes the existence of good hardening properties and resistance to brittle, while silicone rubber or fluoro rubber inner core at a high temperature of 205 ℃ can still maintain good flexibility.
4. Test results show that the physical properties of silicone rubber or fluoro rubber and chemical properties of PTFE combine O-ring is formed, while maintaining the properties of other rubber O-qing, but also has good resistance to compression.
5. The anti-friction PTFE low coefficient of friction, making it be the O-ring family friction force smallest species, to reduce equipment wear and improve equipment efficiency power and a great help and support.
6. High pressure resistance up to 35Mpa, 5 Mpa or more is recommended to use a pressure type ring.
7. Excellent sealing durability, long life compared to any other made of rubber or pure PTFE O-ring seal and has an unparalleled long-life, especially in demanding media applications.
8. Non-toxic, clean and temperature resistance make it be essential accessories in food, fine chemicals, bio-industry and other scientific research field.
Application:
Used in erospace, automotive, chemical, petrochemical, chemical, food industry, biotechnology, clean water, machinery industry, sewage treatment etc.
