FEP/PFA Encapsulated O-Rings
FEP / PFA Encapsulated O-ring
An encapsulated O-ring is a rubber O-ring that’s completely covered by a smooth, seamless layer of FEP or PFA. The plastic coating surrounds and protects the rubber core from liquids, chemicals and other surroundings. This gives you the soft, springy sealing action of rubber plus the tough temperature and chemical resistance of FEP/PFA.
Technical
Benefits of Encapsulated 'O'-Rings and Seals
Very tough against strong chemicals and doesn’t let gases pass through easily.
Low friction, so equipment parts wear out less.
Keeps the stretchy, sealing action of a rubber O-ring.
Uses a single, standard material (MOC), so you don’t need different parts for different jobs.
Doesn’t get permanently squashed or slowly flow like some solid O-rings do.
Can handle heavy cleaning and sterilizing cycles (CIP = clean-in-place, SIP = sterilize-in-place).
The surface won’t corrode.
Meets common sanitary and safety rules (3-A Sanitary, USP Class VI, FDA 21 CFR 177.1550, BSE/TSE animal-safety, and EU Regulation 1935/2004).

Encapsulated O-Rings | FEP & PFA Encapsulated O-Rings Supplier in Dubai, UAE
Premium Encapsulated O-Rings Supplier in Dubai – FITCO Orings Trading LLC
At FITCO Orings Trading LLC, we provide high-performance FEP and PFA encapsulated O-rings designed for applications where standard elastomer seals fail. Our encapsulated O-rings combine the elasticity of rubber cores with the superior chemical and temperature resistance of fluoropolymer coatings — making them the perfect sealing choice for harsh industrial environments.
Serving industries across oil & gas, chemical processing, food, and pharmaceutical sectors, FITCO delivers reliable and durable sealing solutions across Dubai, UAE, and the Middle East.
What Are Encapsulated O-Rings?
An encapsulated O-ring consists of an inner elastomer core (typically Silicone or Viton®) enclosed within a seamless jacket of FEP (Fluorinated Ethylene Propylene) or PFA (Perfluoroalkoxy).
This unique construction ensures:
- Excellent chemical resistance like PTFE
- Elastic memory of rubber
- High-temperature performance
- Low friction sealing
Encapsulated O-rings are ideal when standard O-rings swell, degrade, or lose elasticity in aggressive chemical or high-temperature environments.
Types of Encapsulated O-Rings We Offer
At FITCO, we supply two primary types of encapsulated O-rings:
🔹 FEP Encapsulated O-Rings
- Excellent chemical resistance
- Temperature range: -60°C to +205°C
- Non-stick and low-friction surface
- Ideal for most chemical and food applications
🔹 PFA Encapsulated O-Rings
- Higher temperature resistance: up to +260°C
- Greater mechanical strength than FEP
- Suitable for dynamic sealing and aggressive environments
Both options are available with Silicone or Viton® cores, depending on flexibility and temperature requirements.
Key Benefits of Encapsulated O-Rings
✔️ Outstanding resistance to acids, solvents, and hydrocarbons
✔️ Performs under extreme temperature ranges
✔️ Non-stick and low coefficient of friction
✔️ Excellent compression set resistance
✔️ FDA-approved materials available
✔️ Long service life in harsh environments
Encapsulated O-rings offer exceptional performance where traditional rubber or PTFE O-rings fail.
Applications of Encapsulated O-Rings
FITCO’s FEP and PFA encapsulated O-rings are widely used in:
- Chemical & petrochemical industries
- Food & beverage processing equipment
- Pharmaceutical machinery
- Semiconductor manufacturing
- Marine and oilfield applications
- Cryogenic sealing
Their ability to withstand aggressive fluids, steam, and cleaning agents makes them an indispensable component for reliable sealing.
