Mar

Overlook Mar style filler needles are a direct replacement for any size standard needle on a Mar 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.

    Mar uses a threaded design to attach the fluid portion to the gassing portion in their OEM co-ax filler needle. Threaded designs can cause huge problems with cleaning validation.

    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.

    Upchurch compression fittings are used to secure Overlook filler needles to semi-rigid Teflon supply tubing. Teflon tubing is useful for high pressure applications and for products that are sensitive to platinum-cured silicone.
