Back-up Ring-BRT*3/NY/ABA

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.

Nylon back-up ring have excellent insulation properties, are non-magnetic, heat-insulating and light weight. Plastic gaskets made of certain materials also have high temperature resistance, high strength and corrosion resistance. Some products have anti-fall functions and are widely used in various industrial fields.
