Lock Rings for Luers

These threaded lock rings attach over the tapered end of a male slip luer fitting to provide a more secure luer lock connection. Instead of relying on the friction-fit of the male slip, the lock rings provide a twist-and-lock mechanism to prevent accidental disconnection of tubing, syringes, or other components, especially in pressurized or high-vibration systems. They can also be used as a replacement part for existing locking male luer fittings. Engineered to ISO standards, the precision-molded rings deliver secure, leak-resistant performance across medical, laboratory, and industrial fluid systems. Their universal design ensures seamless compatibility with any compliant components, regardless of the manufacturer, eliminating compatibility issues, reducing the risk of leaks, and simplifying the design and assembly process for critical fluid systems.
