Emerson 11A3404X022 Back-Up Ring Seal Protection

The Emerson Fisher Back-Up Ring with part number 11A3404X022 serves as an important component to protect O-rings and other seals in valve systems. Its main function is to preserve the seal from extrusion under high pressure, thereby extending the lifespan of the seal and the integrity of the system. This back-up ring is typically used in applications where pressures can exceed 70 bar. Made from a durable material, it prevents the seal from entering gaps or spaces in the housing, which can lead to leaks or premature wear. The 11A3404X022 is compatible with various Emerson valve types and ensures that the seal operates reliably even under demanding operating conditions. An essential item for maintaining sealing performance and avoiding downtime. Request replacement part now.
