• Gauge (20G): A 20-gauge needle has a standard inner diameter of 0.60mm and an outer diameter of 0.91mm, and is color-coded pink. It is suitable for high-viscosity liquids like oil-based suspensions, adhesives, and sealants.
• Needle type: For industrial applications, blunt-tip needles are used to apply liquids precisely without scratching or puncturing a surface. Some needles may have angled or folded tips for specific applications.
• Luer lock hub: Needles with a Luer lock hub have a threaded connector that provides a secure, leak-proof connection to a syringe or dispensing barrel, preventing the tip from popping off under pressure.
• Applications: Industrial dispensing needles are used for applying lubricants, sealants, and inks in electronics manufacturing, jewelry making, and other precise craft or repair work.
