FEP/PFA-encapsulated O-rings
FEP/PFA-encapsulated O-rings combine the elastic properties of the core material with the high chemical resistance of an FEP or PFA encapsulation. They are particularly suitable for aggressive media, demanding chemicals and extreme ambient conditions.
These O-rings offer high chemical resistance, a wide temperature range, low friction and good non-stick properties.
Temperature Ranges
FEP encapsulation: -60 °C to +205 °C, briefly up to +260 °C
PFA encapsulation: -60 °C to +260 °C, briefly up to +300 °C
Advantages
- Excellent chemical resistance
- Wide temperature range
- High pressure resistance
- Non-stick properties
- Low friction
- Self-lubricating surface
- Low gas permeation
- Cost-effective and reliable sealing solution
Available Cross-Sections
FEP silicone and FEP Viton are available in all common standard cross-sections:
1.78 | 1.80 | 2.00 | 2.40 | 2.50 | 2.62 | 3.00 | 3.50 | 3.53 | 4.00 | 5.00 | 5.33 | 5.70 | 6.00 | 6.99 | 7.00 mm
Custom dimensions can also be produced at short notice. In addition, FEP silicone Camlock gaskets from ½” to 3″ are available.
FFKM O-rings and FFKM seals
FFKM seals are designed for particularly demanding applications. They offer very high resistance to aggressive liquids and gases and are suitable for application areas with high thermal and chemical loads.
Depending on the design, temperature ranges from -40 °C to +320 °C are possible.
Typical Application Areas
- Aggressive chemicals
- High temperatures
- Demanding process media
- High requirements for resistance and service life
- Sensitive industrial and process applications
Coated O-rings
Coatings can specifically improve the function of an O-ring. They reduce friction, facilitate installation, support lubrication or increase resistance to certain operating conditions.
INNSEALS offers various coating options matched to the application, material, medium and installation situation.
Possible Coatings
- Molykote
- Talcing
- Silicone coating
- PTFE
- PTFE-FDA
- PTFE-TR

Your FAQs Answered
Frequently Asked Questions:
An O-ring is a ring-shaped seal made of elastic material. It is used to reliably seal two components and prevent the escape of liquids or gases.
O-Ringe kommen in vielen Bereichen zum Einsatz, z. B. in Hydrauliksystemen, Pneumatik, Maschinenbau und Automobilindustrie. Sie dichten statische und dynamische Verbindungen ab.
O-rings are manufactured from various elastomers, such as NBR, FKM (Viton), EPDM or silicone. The material choice depends on temperature, medium and operating conditions.
Inner diameter, cord diameter, material and operating conditions such as temperature, pressure and media resistance are important. Precise matching prevents premature wear.
Service life depends on material, load and environmental conditions. With correct selection and application, O-rings can be very long-lasting, but wear faster under extreme conditions.
