FAQ
How do gauge numbers relate to diameter and color?
The larger the gauge number, the finer the diameter. Jensen Global follows the industry standard of color-coding gauge numbers, so you can identify the right needle by color at a glance when switching or restocking — see the specification table on each needle's page for details.
How do I choose between stainless steel, PTFE and tapered needles?
Standard stainless steel works for most fluids; PTFE is better for adhesives that stick easily, such as cyanoacrylate or UV-cure adhesives; tapered needles reduce flow resistance for medium-to-high viscosity fluids.
