PTFE BACKUP RING
Industrial PTFE Back-up rings come with several applicable benefits when it comes to using them for relevant requirements under suitable conditions. As the name suggests, PTFE backup rings are designed in a way that makes the products usable in preventing the extrusion in rubber O-ring sealing systems.
Hydraulic and pneumatic systems deal with certain dynamic and static applications where in O-rings provide effective sealing solutions. However, O-rings have one disadvantage of extruding into the clearance of mating surfaces when exposed to increased temperatures and pressures. Elevation in atmospheric pressure or temperature poses a great burden and effect on the physical and chemical properties of the rubber O-rings, and this causes the rings to extrude further until failure and eventual leakage.
What are PTFE Backup Rings and How do They Help?
In order to avoid the extrusion in o-ring rubber sealing systems, experts have fabricated the specially-engineered PTFE back-up rings. PTFE backup rings make the usage of o-rings for static and dynamic applications in hydraulic and pneumatic systems more efficient. The PTFE backup rings are not as succeptable to the effects of high pressure , and hence offer extended protection to the o-rings.
The typical applications of PTFE backup rings are:
- Hydraulic cylinders
- High pressure valves
- High-pressure hydraulic and
- Pneumatic systems
- Aerospace sector
