Detailed Product Description
|
PTFE Bronze Filled BRT Nylon Back-up Ring PTFE U Cup Seal Description Back-up Rings are protective and supporting elements with no
sealing function. Made from extrusion-resistant materials ,and
they usually have a rectangular cross section and are installed in a
groove with an elastomer O-Ring. Due to their tight fit in
the housing, Back-up Rings prevent extrusion of the
pressurized elastomer sealing element into the clearance or
extrusion gap.Using Back-up Rings allows O-Rings to be utilized in
higher pressure applications, where larger extrusion gaps are
required and where there are reciprocating or rotating
movements. They also compensate for large temperature fluctuations. Porduct Display Dimensions
