Option 2. I know my syringe part number, but not the termination

If you know the syringe part number but do not know what termination it has, you can search for the part number by clicking on the magnifying glass at the top of any page on the Hamilton website and then entering the part number in the Search box. The product page will list the termination and the compatible needle hub. Once the termination is determined use Option 1 to find the page where the appropriate needles are listed.

Option 3. I have a plastic syringe and need a compatible needle

Many plastic syringes use an industry standard Luer or Luer Lock connector. For these syringes both the Hamilton Metal Hub and the Kel-F Hub needles are compatible.
