Corteco NBR vs FPM - understanding the differences

One of the most common questions in the sealing industry is:

  • Corteco NBR vs FPM
  • which oil seal material to choose
  • NBR or FPM Viton
  • differences between NBR and FPM
  • high temperature shaft seal

Choosing the correct sealing material has a major impact on:

  • equipment durability
  • leak protection
  • chemical resistance
  • temperature resistance
  • machine reliability

Incorrect material selection may lead to:

  • oil leakage
  • seal cracking
  • overheating
  • industrial equipment failure
  • costly production downtime

That is why the choice between Corteco NBR and FPM oil seals should always depend on the operating environment.


What are NBR oil seals?

NBR - the industrial standard

NBR is the most commonly used sealing material for standard industrial and automotive applications.

NBR oil seals are valued for:

  • good oil resistance
  • cost-effective pricing
  • wide availability
  • versatile applications

Typical applications include:

  • industrial gearboxes
  • pumps
  • motors
  • standard hydraulic systems
  • industrial machinery

  • Corteco NBR
  • NBR shaft seal
  • industrial NBR seal

Advantages of NBR oil seals

Why is NBR so popular?

Main advantages of NBR material:

  • economical solution
  • good resistance to mineral oils
  • good flexibility
  • broad industrial usage
  • excellent stock availability

For many standard industrial systems, NBR is fully sufficient.


Limitations of NBR material

Despite its popularity, NBR also has limitations.

The most important include:

  • limited high temperature resistance
  • lower chemical resistance
  • shorter lifespan in aggressive environments
  • limited compatibility with some industrial media

In demanding applications, FPM FKM Viton is often used instead.


What are FPM FKM Viton oil seals?

FPM - material for demanding applications

FPM FKM Viton is a sealing material designed for operation in extremely demanding industrial conditions.

Main advantages:

  • excellent temperature resistance
  • resistance to aggressive chemicals
  • resistance to synthetic oils
  • extended service life
  • highly stable operation

Typical applications include:

  • hydraulic systems
  • chemical industry
  • turbines
  • power generation
  • premium automotive systems

  • FPM oil seal
  • Corteco FPM
  • Viton shaft seal
  • high temperature oil seal

NBR vs FPM - key differences

Operating temperature

NBR

Best suited for standard operating temperatures.

FPM

Designed for very high temperatures and continuous operation.

In high-temperature applications, FPM significantly outperforms NBR.


Chemical resistance

NBR

Good resistance to standard oils and lubricants.

FPM

Much higher resistance to:

  • chemicals
  • fuels
  • synthetic oils
  • aggressive industrial media

Service life

NBR

Good durability in standard operating conditions.

FPM

Significantly longer service life in demanding environments.


Price comparison

NBR

Economical solution for most standard applications.

FPM

Higher cost due to advanced material properties.

However, in demanding industrial systems, the higher price often means:

  • fewer failures
  • less downtime
  • lower maintenance costs

When should you choose NBR?

NBR is the right choice when:

  • operating temperatures are standard
  • there are no aggressive chemicals
  • cost efficiency is important
  • the system uses standard oils

Most common applications:

  • standard industrial machinery
  • automotive systems
  • gearboxes
  • pumps
  • hydraulic equipment

When should you choose FPM FKM Viton?

FPM is the best choice when:

  • high temperatures are present
  • aggressive chemicals are used
  • long service life is required
  • the system operates continuously under heavy load

Typical applications:

  • chemical industry
  • power generation
  • high-pressure hydraulics
  • premium automotive systems
  • turbines and high-temperature equipment

Why correct material selection matters

Incorrect seal material selection may cause:

  • oil leakage
  • shaft damage
  • sealing failure
  • industrial breakdowns
  • expensive production downtime

That is why industrial users increasingly search for:

  • NBR vs FPM
  • which shaft seal to choose
  • high temperature oil seal
  • Corteco FPM or NBR
