Product application
In a sealing application, backup rings provide added extrusion resistance and prevent damage to o-rings and seals when subjected to high pressures, larger extrusion gaps, and/or high temperatures.
In today's global economic integration, in order to adapt to the increasingly fierce market competition, we always take "innovation, quality, service" as the purpose, and constantly improve production technology and develop new PTFE Oil and Gas Back up Rings Seal Spiral Backing Rings. The company will continue to increase investment in product research and development, and continue to optimize the product structure. It is out of deep understanding and high attention to social responsibility that in recent years, through the joint efforts of all levels of the company, we have actively assumed responsibility.
