Replacement intervals depend on service conditions: typically 3-5 years for continuous high-pressure service, or when leakage exceeds 0.1% of rated flow. Regular inspection every 6-12 months is recommended.
Minor damage can sometimes be repaired by precision lapping, but replacement is generally required for significant wear, corrosion, or deformation to maintain sealing performance.
