Product Summary

pdfpdfpdfpdf

Back-up ring is combination of high pressures and high temperatures,which 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. Back-up rings are used with a primary seal such as an o-ring in both dynamic and static applications to prevent extrusion of the o-ring when it is subject to high pressures, there are excessive extrusion gaps present in the application, or the o-ring is exposed to elevated temperatures. Elevated temperatures (160°F and higher) impose a severe burden on the physical and mechanical properties of rubber O Rings which further increases their tendency to extrude. Two back-up rings should be used with one on each side of the primary seal.
