How Much Does Applied Materials 0021-40940 Cost in 2026?
Used units for 0021-40940 (Centura DPS Alumina Ring) range from $12,000 to $18,000 in 2026, depending on erosion depth and service history. Refurbished variants (with <0.2mm material loss and full RF recalibration) cost $8,500 to $14,000. This represents 40–60% savings vs. Applied Materials’ 2026 new pricing ($22,000–$30,000). Critical caveat: rings with >0.3mm erosion near the RF coupling slot will fail oxide etch uniformity specs (<±3% required), even after resurfacing. Always verify service logs for plasma arcing incidents in the prior 12 months.
