Fluororubber O-Ring Sealing Gasket

No.LL-REG-01
Fluororubber O-Ring Sealing Gasket (also known as FKM or Viton gasket) is a high-performance sealing material composed primarily of fluorinated polymer elastomers. The fluorine atoms in its molecular structure endow it with exceptional properties unmatched by ordinary rubber.

Description

Core Features

  • Exceptional Thermal Stability: Operates reliably in continuous temperatures ranging from -20℃ to 200℃, and can withstand intermittent spikes up to 250℃.

  • Superior Chemical Resistance: Offers unmatched resistance to oils, fuels, lubricants, and most mineral acids. It is the material of choice for environments where standard rubber (like NBR) would degrade.

  • Excellent Compression Set: Maintains its original shape and sealing force over long periods, even under high-temperature and high-pressure conditions, ensuring a leak-free lifecycle.

  • Weathering & Ozone Resistance: Highly immune to atmospheric aging, UV radiation, and ozone, making it ideal for critical outdoor or aerospace applications.



Technical Advantages

  • Low Gas Permeability: Provides an outstanding barrier against gas diffusion, which is critical for high-vacuum applications and fuel system containment.

  • High Precision Tolerances: Manufactured using precision molding technology to meet international standards such as AS/BS (AS568), JIS, and DIN, ensuring a perfect fit in standard grooves.

  • Flame Retardant Properties: Naturally self-extinguishing and highly resistant to ignition, adding an extra layer of safety in high-heat industrial environments.

  • Versatile Hardness Options: Available in various Shore A hardness levels (typically 70, 75, or 90 Shore A) to match specific pressure and gap requirements.


Applications
Fluororubber gaskets are widely used across key industries for their high-temperature, chemical-resistant, and reliable sealing performance:

  • Petrochemical: Seals for pipelines, valves, reactors, refinery equipment, and storage tanks (resisting corrosive media, high temperatures, crude oil, and chemical additives).
  • Automotive & Aerospace: Engine (crankshaft, valve stem), fuel system, aircraft engine, and hydraulic system seals (withstanding oils, extreme temperatures/pressures).
  • Electronics & Semiconductor: High-purity chemical delivery system and electrical insulation seals (preventing contamination).
  • Pharmaceutical & Food Processing: Bioreactor, pharmaceutical, and food machinery seals (complying with FDA/3A standards, resisting CIP/SIP cleaning, hot water, steam, and disinfectants).
  • Other Industries: Hydraulic systems, analytical instruments, separation equipment, high-pressure pipelines, and pressure vessel seals (ensuring pressure resistance, measurement accuracy, and leak-free operation).


Customization Options
Available in standard shapes (round, square, rectangular) or custom designs according to customer drawings, suitable for sealing applications ranging from miniature precision instruments to large industrial equipment.
