Viton^® / FKM Rubber Seal (Extrusion Profile)

Key Features

Product Description

At PTI Global Products, we specialize in Viton^® / FKM rubber extrusion seals, engineered for industries that demand maximum durability, chemical resistance, and long-term sealing reliability.

Our FKM seals are manufactured from high-grade fluorocarbon rubber compounds, carefully formulated to meet the specific performance requirements of each application. We offer a wide range of material grades, including:

  Viton^® Extreme — for aggressive chemical environments
  Viton^® Food Grade — for food & processing industries

These seals are designed to perform in harsh industrial conditions where standard materials like EPDM or NBR are not sufficient.

Bespoke Manufacturing (Made-to-Order Solutions)

At PTI Global Products, we provide both standard profiles and custom-engineered sealing solutions to meet precise industrial requirements. 

For custom projects, customers can submit:
  Technical drawings (2D / 3D)
  CAD files
  Physical samples

Our engineering team will support you in:
  Profile design optimization
  Tolerance control
  Material selection (compound formulation)
  Hardness & performance tuning

Production depends on tooling requirements and MOQ, based on design complexity.

FAQ — Viton^® / FKM Rubber Seal

1. What is a Viton^® (FKM) rubber seal?
Viton^® (FKM) is a fluorocarbon elastomer engineered for high-performance industrial applications. It provides exceptional resistance to heat, oil, fuel, and aggressive chemicals, making it ideal for environments where standard materials like EPDM or NBR cannot perform effectively.

2. What temperature can FKM rubber seals withstand?
FKM rubber seals can operate continuously at temperatures up to 260°C, with higher peak resistance depending on the specific compound grade. They are widely used in ovens, high-temperature machinery, and energy systems.

3. How does FKM compare to EPDM and NBR?
FKM offers superior performance in:
  High temperature resistance
  Oil and fuel resistance
  Chemical resistance

In comparison:
  EPDM is ideal for water, steam, and weathering
  NBR is suitable for general oil applications

4. What applications are suitable for Viton^® rubber seals?
FKM seals are commonly used in:
  Oil & Gas
  Chemical Processing
  Automotive & Aerospace
  Industrial Machinery
  Power Plants
  Cleanroom & Electronics (Silicone-Free applications)

5. Are FKM seals resistant to oil and fuel?
Yes. FKM provides excellent oil and fuel resistance, maintaining stability without swelling or degradation even under continuous exposure.

6. What chemicals can FKM resist?
FKM is resistant to:
  Many types of acids
  Industrial solvents
  Harsh processing chemicals
However, chemical compatibility should be verified case-by-case for critical applications.

7. What does low compression set mean, and why is it important?
A low compression set means the rubber can recover its original shape after being compressed, which ensures:
  Consistent sealing performance
  Reduced leakage risk
  Longer service life

8. Can Viton^® (FKM) seals be used outdoors?
Yes. FKM offers strong resistance to UV and ozone, making it suitable for outdoor environments without cracking or degradation.

9. What is the service life of FKM rubber seals?
The service life depends on operating conditions, but FKM seals typically last significantly longer than conventional rubber materials, helping reduce maintenance frequency and downtime.

10. Can you manufacture custom FKM rubber seals?
Yes. We provide custom (Bespoke / Made-to-Order) manufacturing, and customers can submit:
  Drawings
  2D / 3D CAD files
  Physical samples
Our engineering team will evaluate and propose the optimal solution.

11. Is there a minimum order quantity (MOQ)?
Yes. MOQ depends on:
  Product type
  Tooling requirements
Our team will recommend the most suitable MOQ based on your project.

12. Are certifications and technical documents available?
Yes. We can provide:
  COA (Certificate of Analysis)
  Technical Data Sheets
These documents support factory audits and quality assurance requirements.

13. What is the production lead time?
For custom orders, the typical lead time is 15–30 days, depending on:
  Profile complexity
  Order quantity

14. How do I select the right FKM seal for my application?
Key factors to consider:
  Operating temperature
  Chemical exposure
  Profile design (installation type)
  Compression requirements
