The Haskel MS28774-024 Back-Up Ring Pack of 10 is a support sealing component used in combination with O-rings to prevent seal extrusion under pressure. It is designed to reinforce O-ring performance in high-pressure industrial applications, such as pumps, valves, and fluid systems where sealing integrity is critical. The ring fits into the seal groove alongside the primary O-ring, ensuring that gaps do not open up and the main seal is protected from deformation or damage. Made to standards compatible with MS28774 ring specifications, it helps extend seal life and improve reliability. This backup ring is ideal for maintenance and preventive replacements to reduce system failures.
