Our PTFE backup rings are engineered to withstand a wide range of chemicals, making them an ideal choice for applications involving harsh substances. Whether it’s oils, gases, or other aggressive media, these rings maintain integrity and performance, offering you peace of mind no matter the environment.

PTFE backup ring are high-performance sealing solutions that can be used in many industrial applications. Made from polytetrafluoroethylene (PTFE), these rings boast exceptional chemical resistance, can withstand extreme temperatures ranging from -200degC to +260degC, and exhibit minimal friction properties. These rings are ideal for environments in which other materials may degrade or fail. The inherent resilience in PTFE allows the backup rings to retain their structural integrity with time. This extends service life, reduces maintenance costs and increases reliability. PTFE back up ring are also capable of enduring high pressure situations without deforming. This ensures a reliable seal, and prevents system leaks. They improve the efficiency and reliability by adding an extra layer of protection to the gap between sealing elements. PTFE backup ring is an essential component for any sealing application. Customers benefit from increased safety, decreased downtime and lower operating costs.

Frequently Asked Questions

Of course, we can customize pfe products to your satisfaction according to your material, size and process

The maximum size of ptfe molded plate can reach 2000mm long * 2000mm wide * 390mm thick,
ptfe rods have a maximum length of 4000mm and a diameter of 500mm

PTFE is essentially chemically inert and is highly resistant to chemical attack up to its 500º F. maximum continuous operating temperature. As indicated in the referenced PTFE Handbook above, there are a few exceptions including molten alkali metals, turbulent liquid, or gaseous fluorine; and a few fluorochemicals, such as chlorine trifluoride, ClF3, or oxygen difluoride, OF2, which readily liberate free fluorine at elevated temperatures.  Several tables are available on the web supporting appropriate usage of PTFE with chemicals and various concentrations and temperatures. 

We have a set of strict quality testing system, never expected finished products, will be tested and registered, traceable

The general production cycle of ptfe products is about 15 days, and the delivery date can be agreed on for customized products
