DLSEALS PTFE + bronze back-up rings for cylinders COMPRESSOR RING

Product description

Back-up Rings have no intended sealing function.

They are protective and supporting elements made from extrusion-resistant materials which generally have a rectangular cross section. They are installed in a groove together with an elastomeric sealing element preferably with a corresponding O-Ring in static applications.Due to the tight fit of the Back-up Ring in the housing, they prevent extrusion of the pressurised elastomeric sealing element into the sealing gap.

Advantages

● Low friction resistance, no creeping phenomenon ● The dynamic and static sealing effects are quite good ● no viscous phenomenon ● Good performance when there is lubrication and no lubrication ● The groove structure is simple ● High-pressure resistance and adaptability to working conditions ● Multiple choices of specifications
