National Instrument / Filamatic

Overlook National Instrument style and Filamatic style filler needles are a direct replacement for any size standard needle on a National Instrument / Filamatic liquid filling machine. Overlook filler needles are superior to the OEM design in the following ways:

  • Superior hose barb design ensures secure tube connection to filler needle.
  • Electropolished surface finish for ease of cleanability.
  • Laser marking / engraving of custom identification.
  • Laser welding of Overlook needles leaves no weld witness on ID of fluid path.
  • Co-ax (gas purge + fill) filler needles utilize simple, two-piece design for ease of cleanability.
  • Wide range of custom tip geometries / coatings to enhance dispense characteristics.
  • Single-use filler needles only available from Overlook.

    National Instrument uses a threaded design to attach the downstream portion of their OEM filler needle to the mounting hub. Threaded designs can cause huge problems with cleaning validation.

    Notice Overlook's advanced hose barb design on our National Instrument style filler needle. This provides a significantly improved silicone tubing connection compared to the smooth hose barb on an OEM National Instrument filler needle.

    The overwhelmingly complex design of an OEM National Instrument co-ax filler needle is unnecessary, extremely difficult to properly clean and also very costly.

    Overlook relies on a simple silicone o-ring to maintain proper fitment of the fluid portion into the gassing portion of our co-ax filler needle.

    Notice the Teflon coating on the inner fluid portion. Teflon reduces the chance of fluid collection on the OD and end of the filler needle.
