Synerings®

HOW DOES THE SYNERING® WORK?
The Synering® is an advanced seal designed for extreme environments where conventional seals fail. Its unique design combines a PTFE element with exceptional chemical and thermal resistance with a booster spring for consistent sealing force.

How it Works
- Installation: The Synering® is radially or axially mounted.
- Initial Sealing: The spring activates the sealing lips for a positive seal, even without system pressure.
- Pressure Increase: System pressure further activates the seal, increasing sealing force.
- Dynamic Applications: During movement, the spring compensates for wear and maintains a tight seal.
- Thermal Cycling: The spring retains its force and continuously activates the seal under temperature fluctuations.
Benefits
- Excellent chemical and thermal resistance
- High and consistent sealing force
- Reduced wear and extended service life
- Accommodates slight alignment and tolerance variations

Alternatives

Back-up Rings
Back-up rings are used for static and dynamic applications in connection with O-rings, to prevent extrusion of the O-ring into the diametrical clearance.

Rotary Seals
Rotary seals are used in applications with oscillating or rotating movements in order to retain liquid lubricants and to prevent the penetration of dirt and water.

Rod Seals
The Rod Seal consists of a single-acting PTFE rod sealing ring and an O-ring. They are combined as a single unit and are appropriate for rods and plungers in hydraulic cylinders.
