Suction roll seals
Metso's suction roll seals are marketed under the brand name
FlexSeal. FlexSeal is used as the standard seal material for all new suction rolls, and as a replacement for conventional seal strip materials in the case of older rolls.
FlexSeal is a rubber-graphite based material that also includes some special components for such beneficial seal strip properties as flexibility, excellent wear resistance and low noise.
Metso manufactures FlexSeal strips completely in-house, all the way from the mixing of rubber to vulcanization and machining. This facilitates continuous related research and product development.
FlexSeal can be used on all paper, board and tissue machines and drying lines, and at all suction roll sealing positions.

The properties of FlexSeal provide superior performance over traditional rubber-graphite seals.
- The FlexSeal formulation is substantially better in the areas of wet and dry wear. Customers have even doubled the life of seals with FlexSeal and thus significantly reduced their maintenance and roll change needs.
- The flexible material conforms to the shell surface better and faster, and the desired vacuum level is achieved quicker.
- The superior handling characteristics of FlexSeal reduce the risk of damage during handling and mounting.
