Our Medical Check Valves

Our medical check valves are manufactured on high speed automated equipment and each valve is 100% function tested as part of the assembly process. These assembly methods and robust valve design result in the highest quality product with defect levels below 1 part per million.

PVC Valves

Our PVC medical check valves are incorporated into critical airway management devices such as endotracheal tubes, tracheostomy tubes, laryngeal mask airways (LMA’s), Simplastics- post TURP Catheters, Occlusion Catheter, Ureter catheter, embolectomy catheter and disposable facemasks. They are typically glued into a pilot line or device.
