NEW
VR pneumatic seal
Low Friction
The proven design is now also available in a low-friction version. By vulcanizing a special film onto the sealing lip, the seal can operate without lubrication – making it ideal for applications with strict requirements for cleanliness, low friction, and minimal maintenance.
This innovation builds on our extensive experience in elastomer processing and offers a smart solution for modern machine designs in pharmaceutical, food processing, and automation technology.
Advantages
Lubrication-free operation – ideal for hygiene-sensitive or cleanroom environments
Reduced friction – lower wear and extended service life
No metal insert – easy snap-fit installation without additional hardware
Combined function – sealing and wiping in a single component
Cost-efficient – reduced lubrication effort, less maintenance required
Retrofittable – available as a custom version for other designs on request
Applications
- pneumatic cylinders
- Compact presses for the pharmaceutical industry
- Food processing equipment
- …and possibly your application too – feel free to contact us!
