At NES, we offer a specialist service to produce and supply PFA encapsulated O-rings for a wide range of applications and industries.  Our PFA O-rings can be used in any cross-section, diameter, or size to fit your specific needs.  We take pride in our capacity and specialist service to provide high-quality PFA encapsulated O-rings to our customers. 

Applications and Industries 

Our PFA encapsulated O-rings have been used with great success in a variety of industries, including the food industry, chemical and petrochemical industries, and pharmaceutical companies.  These O-rings can be used in a range of applications, making them a versatile and valuable solution for many issues. 

High-Quality Production and Supply 

We are committed to providing our customers with only the highest quality and most reliable PFA encapsulated O-rings.  Each of our products is carefully monitored and inspected to ensure their quality and reliability. 

Benefits of PFA Encapsulated O-Rings 

Our PFA encapsulated o-rings offer several benefits, including: 

• Cost-effectiveness: PFA O-rings are a cost-effective alternative to traditional PTFE O-rings. 
• Resistance to gas permeability: Our O-rings are highly resistant to gas permeability, making them ideal for applications that require tight seals. 
• Resistance to aggressive chemicals: Our O-rings have been tested to keep out potentially aggressive chemicals, ensuring long-lasting performance. 
• Low friction levels: Our O-rings have low friction levels, which reduces wear and tear on equipment and promotes longer-term use of applications. 
• Resistance to cold flow and compression: Our O-rings are resistant to issues such as cold flow and compression that can occur with solid O-rings. 
• Adaptive force of sealing applications: Our O-rings have an adaptive force of sealing application, ensuring reliable performance in a range of applications. 

Advanced Properties of PFA Encapsulated O-rings 

Our PFA encapsulated O-rings have the same properties as FEP, but with some notable differences.  PFA O-rings have greater heat resistance properties of -60°C to +204°C (with an FKM core) and -60°C to +260°C (with a Silicone core).  They also offer greater resistance to chemicals due to a seamless join that is completed through an advanced heat moulding process.
