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.
back-up ring is usually used with O-ring in order to bear greaterpressure. Customer can order according to the size ofo-ring for convenience.(Rubber back-up ring &PTFE back-up Ring).
Rubber back-up ring: the material always is NBR90,and our stock more is NBR90.*Usually,In the table,the dimension we have some stock,other dimension all can custom-make.
We have thePTFE Back-up ring more is cave rings no split.it has the same function ofrubber back-up ring, but its application range is wide.the dimension we have some stock, other dimension all can custom-make.
PTFE is a high-performance engineering plastic with many excellent properties. PTFE retaining rings have the following characteristics:
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.
