FEY Labyrinth Sealing Rings

Protect components in dirty and abrasive environments up to 700oC

fk5-hfl single & double laminar sealing rings

For the sealing of axial compensators in exhaust pipes of internal combustion engines, manifold sheet metal pipe connections, exhaust gas recirculation systems and turbochargers

"FK5-HFL" application single and double laminar sealing rings

Single and double wound laminar sealing rings with the identification "FK5-HFL" are made from high-temperature chrome-nickel steels and are designed for the sealing for axial and radial compensators at exhaust pipes of internal combustion engines, exhaust gas recirculation systems, exhaust valves, turbochargers, mobile and stationary power units. Especially for applications that deal with high operating temperatures and high axial and radial movements due to thermal expansions.

Ordering Information

The ring diameter information must match the housing or shaft diameter dimensions ‘D1’ for all enquiries and/or orders. The rings can be ordered individually or in sets. 

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.
