Teflon Backup Rings
Seal Dynamics offers all industry standard as well as special configuration backup rings for use in all industries. Backup rings are typically made of PTFE (Polytetrafluoroethylene). Back-up rings are intended for use in high pressure hydraulic and pneumatic systems as anti-extrusion devices in conjunction with rubber O-rings.

The most common industry standards for PTFE backup rings are:

Teflon O-rings
Seal Dynamics offers high quality Teflon® O-rings made out of PTFE. We offer them in all standard AS568 O-ring sizes as well as many non-standard sizes. Teflon® O-rings are used in high pressure applications and extreme temperature range applications where a rubber O-rings will not perform.

Special Machine and Molded Teflon Parts
Seal Dynamics offers high quality machined and molded Teflon® parts for many applications and industries. Some common types of TeflonĘ parts available are:

Additional Teflon Information by Industry

Aerospace: Teflon® is widely used in the form of military specification back-up rings.

General Fluid Power Industry: Teflon® is widely used in applications with high pressure and temperature ranges where O-ring do not perform. Teflon also offers an extremely low coefficient of friction and is used where dry lubricity and reduced friction is required in dynamic applications.

Food and Beverage Industry Equipment: Teflon® O-rings are widely used in Food and Beverage processing equipment due to it's inert nature. Teflon is available in various FDA Grade materials that make it acceptable for use in applications that include contact with food and beverages.

Medical: Machine molded Teflon® is also widely used in the pharmaceutical and medical equipment applications due to its inert nature.
