Product Description

Bronze Filled PTFE Big Size Guide Ring


Teflon back-up rings are designed to prevent extrusion in rubber o-ring sealing systems.
Big PTFE Seal generally serve as effective seals for dynamic and static applications in hydraulic and pneumatic systems equipment. One big drawback of such o-rings is their tendency to extrude into the clearance of mating surfaces when subjected to increasing pressures.

The degree of extrusion is a function of o-ring hardness, clearance of mating parts and fluid pressure.

Another variable that must be considered in determining the need for back-up rings is the operating temperature. Elevated temperatures (160 degrees F and higher) impose a severe burden on the physical and mechanical properties of rubber o-rings which further increases their tendency to extrude.

The combination of high pressures and high temperatures is a common occurrence in present day fluid systems. Moreover, the trend is toward still higher pressures and longer resident times at elevated temperatures. This places more emphasis on the role of the back-up ring in preventing o-ring extrusion.
