Component Specifications

Definition
A Luer Lock Connector is a standardized medical-grade component designed to provide a secure, leak-proof connection between syringes, needles, catheters, and other medical devices. It features a threaded locking mechanism that prevents accidental disconnection during fluid transfer, ensuring safety and reliability in medical applications. The connector conforms to ISO 80369 standards for small-bore connectors to prevent misconnections.
Working Principle
The Luer Lock operates on a screw-thread locking principle. The male connector (typically on the syringe) has external threads, while the female connector has internal threads. When connected, the threads engage and are tightened to create a secure mechanical lock. This prevents accidental disconnection due to pressure or movement, while maintaining a fluid-tight seal through the tapered Luer slip interface.
Materials
Medical-grade polypropylene (PP), complying with USP Class VI, ISO 10993 biocompatibility standards. May include additives for color coding, radiopacity, or enhanced chemical resistance.
Technical Parameters
  • Taper 6% Luer taper (ISO 594-1)
  • Leakage Zero leakage at rated pressure
  • Thread Size 6% Luer Lock thread (ISO 594-2)
  • Sterilization Autoclavable (121°C, 15 psi), Gamma radiation, EtO compatible
  • Pressure Rating Up to 400 kPa (58 psi)
Standards
ISO 80369-7, ISO 594-1, ISO 594-2, USP <381>, ANSI/HIMA MD70.1

Frequently Asked Questions

What is the difference between Luer Lock and Luer Slip connectors?

Luer Lock connectors have a threaded locking mechanism for secure connections, while Luer Slip connectors rely on friction fit without threads. Luer Lock is preferred for high-pressure or critical applications to prevent accidental disconnection.

Are Luer Lock connectors standardized globally?

Yes, Luer Lock connectors follow ISO 80369-7 standards to ensure global compatibility and prevent misconnections with other medical device connectors.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
