FFKM 7075 Characteristics

Black perfluoroethers rubber compound, hardness Shore A 60~90.

FFKM 7075 has excellent chemical resistance, good mechanical properties, and excellent heat and chemical resistance.

It is widely used in various acids, alkalis, amines, steam, ethylene oxide, and other media.

It incorporates a new patented curing chemistry with mechanical properties designed to improve sealing performance in high-temperature environments and temperature cycling situations.

The superior heat and oil resistance of FFKM 7075 minimizes the risk of premature seal failure and significantly reduces costly downtime.

FFKM 7075 temperature range

The temperature range is from -15 °C to +327 °C.

What is the difference between FFKM 4079 and FFKM 7075?

FFKM 7075 is designed to set a new industry standard for harsh chemical processing industry (CPI) sealing applications.

It has a longer seal life than FFKM 4079 because of its stronger seal retention and higher heat resistance up to 327°C.

FFKM 7075 also has broader chemical resistance and better cooling set recovery than FFKM 4079. These improvements combine to give you reduced downtime, lower maintenance costs, increased productivity, and higher yields.


Advantages of the FFKM 7075 O rings

  • Enhanced physical properties
  • Enhanced temperature cycling capability
  • Excellent compressibility
  • Low expansion in a variety of chemicals
  • Highly reliable performance
  • Outstanding thermal stability up to 327 °C (620 F)
  • Excellent force retention performance
  • Increased productivity
  • Reduced maintenance costs
  • Maintains process purity
  • Improves safety

Disadvantages of the FFKM 7075 O rings

FFKM 7075 is not recommended for severe water and amine applications.

This is because FFKM 6375 is the compound of choice for amine applications.

We recommend recommending specific chemicals based on your working conditions. For example review the specific chemical, service temperature, and pressure to determine the best FFKM O ring to select for each application

FFKM 7075 O-Rings Manufacturing Method

FFKM 7075 O rings Application

To provide higher sealing performance in dynamic applications requiring low friction, FFKM 7075 O-Rings have a brighter surface than other FFKM parts.

FFKM 7075 was developed specifically for O-rings or custom sealing components for the chemical and hydrocarbon industries with an improved thermal resistance that extends the maximum service temperature to 327°C (620°F).

FFKM 7075 O-rings perform under industrial solvents and aggressive chemicals and electronic grade operating conditions.

FFKM 7075 is also used in quick connector fittings because of its excellent enhanced temperature cycling capability and low expansion in a variety of chemicals.
