Black PPSU Medical Connector | 15mm Miniature CNC Machined Fluid Path Component

We successfully delivered a precision machined black PPSU (polyphenylsulfone) connector component for a medical device manufacturer specializing in surgical fluid management systems. Machined from medical-grade black PPSU, this compact connector measures approximately 15mm in length and functions as a critical fluid path junction within a disposable surgical instrument. The component features precision-milled connection ports and sealing surfaces, combining exceptional chemical resistance with the aesthetic and functional requirements of modern medical devices.

Project Overview

Key Technical Highlights

• Miniature 15mm Design: Precision-machined compact geometry enables integration into space-constrained surgical instruments while maintaining full fluid path functionality.
• Black PPSU Material Excellence: Medical-grade black PPSU offers superior chemical resistance, hydrolytic stability, and the ability to withstand thousands of autoclave cycles without degradation.
• Precision Sealing Surfaces: Machined to ±0.02mm tolerance with Ra ≤ 0.4μm finish, ensuring leak-proof connections with mating luer fittings or tubing interfaces.
• Sterilization Versatility: PPSU withstands all common medical sterilization methods including steam autoclave (134°C), ethylene oxide, gamma radiation, and electron beam.
• Chemical Resistance: Excellent resistance to surgical disinfectants, iodine-based solutions, cleaning agents, and bodily fluids encountered in medical procedures.
• Black Color for Application Specificity: Opaque black provides visual contrast in surgical environments and can indicate specific fluid paths or connector types in complex medical systems.
