FEY Labyrinth Sealing Rings

Protect components in dirty and abrasive environments up to 700oC

fk2 laminar piston rings


Laminar sealing rings "FK2" can be used for previously used and new internal combustion engines in connection with cast iron piston rings. Cast iron piston rings are not required for pistons of hydraulic and pneumatic
equipment, compressors and shock absorbers.

Please contact our technical office for information about ring dimensions, ring materials and groove geometries.

Ordering Information

The ring diameter information must match the housing or shaft diameter dimensions exactly for enquiries and/or orders for all ring types. 
Run and Installation Tests

Run and installation tests under operating conditions must be performed in each case before standard production of FEY laminar sealing rings can begin to determine whether the desired sealing effects can be achieved.
