These are precision-engineered ventilator pressure pump fittings, machined from medical-grade 316L stainless steel. Manufactured in compliance with ISO 13485 medical standards, they are designed for critical medical applications where material purity, reliability, and biocompatibility are paramount. The components feature an ultra-smooth, mirror-like surface finish achieved through advanced polishing techniques, significantly reducing the risk of bacterial colonization. This makes them ideal for ensuring the high integrity and long-term sterility of ventilator gas delivery systems.

These fittings are core components within ventilator pressure pump systems. Their primary purpose is to ensure a secure, leak-proof, and low-friction connection for the precise regulation and delivery of medical-grade air/gases. They are engineered to withstand the high-frequency operation and stringent pressure control demands of critical care ventilators, contributing directly to patient safety and device performance.

Our manufacturing process ensures the highest level of precision and quality:

• CNC Machining: Components are produced using state-of-the-art CNC turning centers, guaranteeing exceptional dimensional accuracy, repeatability, and adherence to tight tolerances required for perfect sealing.

• Mirror-Electrolytic Polishing: This specialized post-machining process eliminates microscopic surface imperfections and creates a flawless, mirror-like finish. This ultra-smooth surface is crucial for minimizing areas where bacteria can adhere and thrive, while also ensuring the low friction needed for optimal system performance.

• Quality Assurance: The entire process, from raw material certification to final inspection, is controlled under a quality management system certified to ISO 13485, ensuring traceability and compliance for medical device applications.
