Viton® P-Profile Seal (FKM)
Key Features
P-Profile Structure (Hollow Bulb Design)
Engineered with a hollow bulb to distribute compression force evenly, ensuring tight sealing even on uneven surfaces or high tolerances.
Effective Sealing with Low Compression Force
Requires less compression than solid profiles, reducing structural stress and extending service life.
High Temperature Resistance up to 260°C
Suitable for continuous high-temperature applications such as ovens, thermal machinery, and energy systems.
Excellent Oil & Fuel Resistance
Resistant to swelling and degradation, ideal for lubrication systems, fuels, and heavy machinery.
Superior Chemical Resistance
Withstands acids, solvents, and aggressive industrial chemicals.
Low Compression Set
Maintains elasticity and sealing performance over time, reducing leakage risks.
UV & Ozone Resistance
Suitable for outdoor applications without cracking or degradation.
Silicone Free
Minimizes contamination risk, ideal for painting processes, electronics, and cleanroom environments.
Long Service Life
Reduces replacement frequency, downtime, and overall maintenance costs.
Fully Customizable (Bespoke Manufacturing)
Available for custom production based on drawings or samples, including hardness (Shore A) and compound formulation.
Product Description
At PTI Global Products, we specialize in Viton® P-Profile (FKM Extrusion Seals), offering both manufacturing and supply of high-performance rubber sealing profiles for industrial applications requiring maximum durability and precision.
The P-Profile design features a hollow bulb structure that enhances compression distribution, allowing effective sealing even in applications with dimensional tolerances or uneven pressure. This makes it particularly suitable for door seals, panel seals, and long-term sealing systems.
We utilize high-quality Fluorocarbon Rubber (Viton® / FKM) and develop customized rubber compounds tailored to specific industrial requirements, including:
High-temperature systems and ovens
Automotive and aerospace industries
Oil and fuel systems
Chemical processing
Utilities and energy sectors
Harsh chemical environments
We also offer specialized grades such as Viton Extreme for aggressive chemical exposure and Viton Food Grade for food and hygienic applications.
Viton® P-Profile seals deliver exceptional performance in heat resistance, oil and fuel resistance, and chemical durability, making them the preferred choice where conventional materials like EPDM or NBR are insufficient.
All products are manufactured using a controlled extrusion process, ensuring precise profile geometry and consistent quality throughout the entire length.
This results in:
Uniform cross-section accuracy
Stable sealing performance
Extended service life
Viton® P-Profile is not just a seal — it is a long-term solution to reduce leakage, minimize downtime, and enhance process reliability.
