The ULTRASITE® valve allows for universal compatibility with both Luer slip and Luer lock connectors. The needle-free valve can simplify the handling and safety of virtually any intravenous procedure. The valve remains closed until a syringe or IV line is attached, eliminating the need for caps or cannulas. Its uniquely designed opening provides rapid, easy access while reducing the chance of accidental touch contamination. The valve also incorporates a positive displacement design that reduces catheter occlusions by preventing blood backflow during Luer removal.
