Back-Up Rings
Precision Engineered Anti-Extrusion Solutions for High-Pressure Sealing Applications
Rubberatkins Back-Up Rings are engineered to support and protect elastomeric sealing elements in demanding high-pressure environments. Also known as anti-extrusion rings, they are designed to work alongside O-rings and other seal configurations, preventing extrusion into clearance gaps and ensuring reliable sealing performance under extreme operating conditions.
Manufactured from a range of high-performance thermoplastic materials, our back-up rings enhance the pressure capability, longevity and reliability of sealing systems across a wide range of industrial applications. Available in solid, split and spiral wound configurations, they can be supplied as standard components or customised to meet specific application requirements.
