For enhanced pressure control and protection

Back-up rings play a crucial role in minimizing extrusion gaps within an O-ring groove, allowing the system pressure to be increased without the risk of leakage.

By providing essential support to elastomeric O-rings under demanding operating conditions, back-up rings extend the life of sealing systems, making them ideal for high-pressure and high-temperature applications. From hydraulic systems to complex industrial setups, our back-up rings ensure effective sealing in even the most challenging environments.

We supply back-up rings in a variety of configurations, including solid, split, and spiral-wound designs, to meet specific application requirements.

Available in robust materials such as PTFE and PEEK, our back-up rings offer exceptional resistance to chemicals and high temperatures. If a standard-size back-up ring isn’t suitable, we also provide custom-designed solutions, including options for high-pressure applications where conventional back-up rings may not support the required system pressure.
