Machinery Repair Shops Hot Seal Brown Color Bronze Filled Ptfe Back Up Ring Brt 40*50*3

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.
