Product overviewThe Scraper A8 is a one-piece wiper designed for rod protection and sealing edge wiping. It is available in NBR, FKM or polyurethane (TPU) and incorporates an additional outer-diameter step to ensure a tighter fit and improved wiping effect.
Materials and suitability- NBR: suitable for hydraulic and pneumatic applications
- FKM: for environments requiring higher chemical and temperature resistance
- TPU: for mobile hydraulic applications with heavy contamination due to excellent abrasion resistance
Field of application- Static and dynamic sealing
- Single-acting and double-acting cylinders
- Linear motion
- Rotating shafts (inactive)
- Oscillating motion
Main useDesigned for wiping and contaminant exclusion on hydraulic and pneumatic cylinder rods to protect internal seals and extend component life.
MaterialsElastomers and polyurethane (TPU).
