Resistance bands

Backup rings are key components of sealing systems that prevent the extrusion and deformation of O-ring seals under high pressure. They are used in hydraulics and pneumatics to reinforce seals in static and dynamic applications. Their main function is to stabilize the O-ring, increasing its durability and effectiveness, especially under high loads. These rings protect against mechanical damage, minimize the risk of leaks, and enable the system to operate in extreme temperatures and aggressive chemical environments.

Back-up Rings are used in hydraulic and pneumatic systems where seals operate under high pressure. They are used in hydraulic cylinders, pumps, and valves to prevent O-rings from deforming. In the aerospace industry, they protect control systems from leaks, while in automotive applications, they seal brake systems and gearboxes. They are also used in the energy sector to secure pipe connections in turbines and systems for transmitting fluids under heavy loads.

Back-up Rings significantly increase the effectiveness and durability of seals, preventing their deformation and extrusion under high pressure. They stabilize O-rings, reducing the risk of leaks and failures in hydraulic and pneumatic systems. Thanks to them, seals operate reliably even under dynamic loads and large temperature differences. They allow for the use of seals in more demanding applications, extending their lifespan and reducing the frequency of servicing, resulting in lower operating costs.
