Luer Check Valves

Our Luer check valves offer a variety of inlet and outlet configurations to suit your fluid control needs. Choose from male Luer lock, female Luer lock, female Luer thread, male slip Luer, and 3mm ID tube inserts for easy integration into medical and lab systems. These valves are compact and lightweight, featuring a latex-free silicone diaphragm and body materials such as MABS, acrylic, or polycarbonate.

With cracking pressures as low as 0.11 psi, these valves are ideal for low-pressure, medical-grade applications including IV lines, sampling systems, and diagnostic devices. Whether you're connecting to a threaded Luer port or pushing into flexible tubing, we offer precision-fit options.
