PTFE back up rings are a sealing element used to enhance and protect the main seal in the system. They are used together with O-rings to achieve an anti-extrusion effect when the system is in a high-temperature and high-pressure environment, thereby protecting and extending the service life of the seal in the system.
With our advantages in PTFE material research and development and production technology, we manufacture and supply PTFE back up rings with outstanding competitive advantages, providing standard and customized sizes according to your needs, including open and non-open PTFE back up rings.
