Material selection is the foundation of seal longevity. We offer this plunger seal in both high-grade NBR and Premium FKM configurations to match specific operational environments. For standard high-pressure water blasting and cleaning equipment, our specialized NBR compound offers exceptional mechanical toughness and wear resistance against abrasive particulates. For operations involving elevated temperatures or aggressive chemical additives, the FKM variant provides superior thermal stability and resists molecular degradation when exposed to hydraulic oils and synthetic lubricants, ensuring the seal profile remains unchanged over extended duty cycles.

Achieving the maximum service life from your 12225.5 seal depends heavily on correct installation and shaft preparation. Before fitting, the plunger surface must be inspected for scoring or pitting is recommended to prevent premature lip abrasion. Because this seal features an interference-fit design, it can be installed with standard pressing tools without requiring complex shaft disassembly. Ensuring the seal is pre-lubricated with a compatible grease prior to startup will prevent dry-running failures and establish a stable low-friction boundary layer for long-term operations.
