Product Description
Part size Introduction
PTFE BACK-UP RING has the same faction of rubber back-up ring,but its application range is wide, have much stock can mail ask the stock list ,and can produce as custimer size.




1. Excellent corrosion resistance
It can resist the erosion of most chemicals, including strong acids, strong alkalis, organic solvents, etc. It can maintain stable performance in various harsh chemical environments and extend the service life of the equipment.
2. Extremely low friction coefficient
This makes it play a good role in reducing friction between moving parts, reducing energy loss and wear. Whether on a high-speed rotating shaft or in a reciprocating mechanism, PTFE retaining rings can provide smooth operation.
3. Good high temperature resistance
It can be used in a wide temperature range and can generally remain stable between -180ºC and +260ºC. This makes it suitable for various high and low temperature working occasions.
4. Self-lubrication
No need to add additional lubricant, it can maintain good lubrication. This not only reduces maintenance costs, but also avoids the impact on the working environment caused by lubricant contamination.
5. Good sealing
PTFE retaining rings can effectively prevent the leakage of fluids or gases and ensure the sealing of the system. It can be used in conjunction with other sealing elements to form a reliable sealing structure.
In practical applications, PTFE retaining rings are widely used in chemical, mechanical, electronic, aerospace and other fields. For example, in valves, pumps, compressors and other equipment, PTFE retaining rings can play a role in sealing, supporting and guiding to ensure the normal operation of the equipment.
