  • Compressed air
  • Compressor lubricant

between the airend, separator system, and cooling system.

Why is the 5.1391.0 gasket important?

A properly sealing 5.1391.0 helps prevent:

Maintaining these connections helps support efficient and reliable compressor operation.

How difficult is it to install?

Replacing the 5.1391.0 is generally a moderate mechanical compressor repair.

The gasket itself is simple, but it is installed in the compressor’s pressurized air/oil piping system.

Before replacement:

  • Shut the compressor down completely
  • Disconnect and lock out electrical power
  • Prevent automatic restart
  • Allow the compressor and lubricant to cool
  • Fully depressurize the compressor
  • Verify the separator vessel and connected piping are at zero pressure
  • Remove the applicable clamp and piping connection

During installation:

  • Remove the old 5.1391.0
  • Clean the mating surfaces
  • Inspect the pipe, sleeve, gasket support, and clamp
  • Position the replacement sealing ring correctly
  • Reassemble the joint without pinching or distorting the gasket
  • Tighten the connection according to the Kaeser service procedure

Someone familiar with rotary screw compressor air/oil piping should generally perform this repair.
