Viton® Solid Round Cord (FKM)
Key Features
Solid Round Design
Uniform circular cross-section ensures even compression in all directions, ideal for groove sealing and O-ring applications.
High Compression Capability
Excellent resistance to compression forces, suitable for high-pressure and tight sealing applications.
High Temperature Resistance up to 260°C
Performs reliably in continuous high-temperature environments such as ovens, machinery, and energy systems.
Excellent Oil & Fuel Resistance
Resistant to swelling and degradation, ideal for oil systems, fuels, and hydraulic applications.
Superior Chemical Resistance
Withstands acids, solvents, and aggressive industrial chemicals.
Low Compression Set
Maintains elasticity over time, ensuring long-term sealing performance and reduced leakage.
UV & Ozone Resistance
Suitable for outdoor applications without cracking or degradation.
Silicone Free
Ideal for contamination-sensitive industries such as paint lines, electronics, and cleanrooms.
Long Service Life
Reduces replacement frequency, minimizes downtime, and lowers maintenance costs.
Custom O-Ring Capability (Cut & Splicing)
Can be supplied as continuous cord or fabricated into custom O-rings.
Product Description
At PTI Global Products, we specialize in Viton® Solid Round Cord (FKM Round Cord Seal) designed for industrial applications requiring maximum durability and long-term reliability.
The round cord profile is engineered to provide uniform compression distribution, making it ideal for use in:
Groove sealing
O-ring applications
Static seals
Selected dynamic sealing applications
Manufactured from high-quality Fluorocarbon Rubber (Viton® / FKM), this material offers outstanding performance in:
High-temperature environments
Oil and fuel exposure
Harsh chemical conditions
This makes it the preferred choice where conventional elastomers such as EPDM or NBR cannot perform effectively.
All products are produced using a controlled extrusion process, ensuring precise diameter tolerance and consistent quality throughout the entire length.
This results in:
Uniform dimensional accuracy
Stable sealing performance
Extended service life
Viton® Round Cord is not just a seal — it is a high-reliability solution for critical industrial applications.
