Piston-Seals

Piston-Seals are responsible for the mechanical functioning of the sealing system. They provide sealing as the cylinder extends and retracts.

ttv Piston-Seals fully meet your requirements: a very long service life, excellent friction properties, the most modern seal geometry and straightforward assembly. They are extremely wear-resistant, even when exposed to very high or very low temperatures. They are resistant to high extrusion forces and materials can be selected individually according to different specific conditions.

Road-Seals

Rod-Seals are the most important seals within a sealing system as they have to bear complete operating pressure. They seal the system on the rod and are hence indispensable for the efficient functioning of a hydraulic or pneumatic system.

ttv Rod-Seals fully meet your requirements: low friction, very compact form and straightforward assembly. They are very resistant to wear, even if exposed to extremely high or extremely low temperatures. They are very resistant to high extrusion forces and are apt for a wide variety of mediums.

Wipers

Wipers prevent contamination caused when the piston rod retracts into the system as dirt, foreign particles, chips and moisture are stripped before entering.

ttv Wipers fully meet your requirements: with excellent friction properties and exceptionally good wear resistance.

Guide-Rings

 

Guide-Rings provide the piston rod with the support and the stability needed for the successful functioning of the sealing. Their usage results in extended primary sealing life. Furthermore, Guide-Rings prevent the direct contact of movable metal parts and hence limit a complete collapse of the system.

ttv Guide-Rings fully meet your requirements: With outstanding friction properties and exceptionally high wear resistance.
