Tips for Best Results
✓ Use the shortest needle suitable for your job — shorter length reduces pressure drop and improves flow control
✓ Always cap needles when not in use to prevent tip clogging and material waste
✓ Inspect before each use — replace bent or clogged needles immediately to maintain dispensing accuracy
✓ 18 GA works best with low-to-medium viscosity adhesives and sealants requiring fine, controlled dispensing
✓ Confirm Luer Lock or Luer Slip compatibility with your dispensing equipment before use
