Single and double laminar sealing rings for sealing axial compensators in exhaust pipes of combustion engines, manifold metal pipe connections, exhaust gas recirculation systems and turbochargers
FK 5 HFL Single and double laminar sealing rings
The rings made of high-temperature resistant chromium-nickel steels are designed for sealing sliding pieces and axial and radial compensators on exhaust pipes of combustion engines, exhaust gas recirculation systems, exhaust gas flaps, turbochargers, mobile and stationary engines. They are used especially when high operating temperatures and high axial or radial displacements occur due to thermal expansion.
Ring materials
| STEEL GRADE | SPRING-RESISTANT UP TO | HARDNESS VALUE | SURFACE TREATMENT | SURFACE PROTECTION | SURFACE COLOUR |
|---|---|---|---|---|---|
| 1.4571 | max. +500°C | On request1) | Vibratory finishing | Dry | Varies 2) |
| 1.4980 | max. +700°C | On request1) | Vibratory finishing | Dry | Varies 2) |
1) Varies depending on the type of thermal treatment! Hardness values depending on ring cross-section, measured in Rockwell HRA or HRC.
2) The surface colour can vary depending on the type of thermal treatment from silber/bluish to brownish/black.

Run and installation tests:
Run and installation tests under operating conditions must be performed in each case before standard production of our laminar rings can begin to determine whether the desired sealing effects can be achieved.
Order information:
For enquiries and/or orders, the ring diameter specification must correspond to the bore diameter (nominal dimension) “D1” exactly. The rings can be ordered individually or in sets.
