Airtight Leak Prevention
The primary role of these port caps is to safeguard your therapy pressure. The Quattro FX frame features ports that allow for oxygen enrichment, but if left open or loosely capped, they become a major source of air leakage. These precision-molded silicone caps provide a high-friction wedge fit that remains secure even under high BiLevel or CPAP pressures, preventing leaks that could otherwise wake you up or compromise your results.
