Replacement Gasket & O-Rings
Complete Viton Sealing Kit for DEAR-MPCVD Vacuum Integrity
The DEAR-MPCVD Replacement Gaskets and O-Rings set provides all sealing components needed to maintain vacuum integrity and reliable operation of the Blue Wave Semiconductor DEAR-MPCVD system. Periodic replacement prevents vacuum leaks and protects critical system components.
Each kit includes four Viton O-rings for quartz tube sealing and one Viton flat gasket for the bottom flange — selected for exceptional chemical resistance, high-temperature stability, and long-term durability in vacuum environments.
Contact us for pricing on single replacement kits or bulk orders. Each kit includes all necessary O-rings and flat gasket for one complete service.

Essential Maintenance for Reliable MPCVD Operation
Diamond CVD Growth
Maintains vacuum integrity during MPCVD diamond growth, ensuring stable plasma conditions and contamination-free deposition environments.
Routine Maintenance
Recommended replacement during scheduled system servicing, after multiple quartz tube changeouts, or when vacuum performance begins to decline.
High-Purity Thin Films
Proper sealing prevents atmospheric contamination and ensures the clean, stable vacuum needed for high-purity thin film deposition applications.
Process Changeovers
Replace seals during major process changeovers involving different dopant chemistries to prevent cross-contamination between experiments.
