The 8 inch quartz caps are precision-engineered components designed to seal and protect quartz tubes, reactors, and boats during high-temperature semiconductor and photovoltaic processes. Made from high-purity fused quartz, these caps provide excellent thermal stability, chemical resistance, and a tight, contamination-free seal.

Their durable construction withstands repeated thermal cycling, supporting consistent process performance and extended equipment lifespan. Compatible with standard 8 inch quartz process tubes and reactors, these caps are essential for maintaining cleanroom-grade conditions and process reliability in advanced wafer fabrication.
