WIPERS
WIPER RINGS
Impurities in hydraulic fluids can cause serious damages to the components of oleodynamic systems, especially to guide systems and seals.
The wipers rings, used in all kinds of cylinder (also in pneumatic ones), prevent dust and dirt to seep between the rod and the cylinder head.
Our range includes:
- SEALPUR 93 wiper rings extremely resistant to abrasion SA-SAG type.
- Nitrile rubber wiper rings also with an external cage or a elastomer coating.
- Wipers rings in two different versions, in bronze filled PTFE and energized by an O-RING.
- Bidirectional wipers SAB type .
All these types of seal elements are gradually replacing the nitrile rubber seals, since they are made of polyurethane, which is very wear-resistant also without lubrication.
