Tapered Tips

A straight blunt tip keeps a constant inner diameter from hub to outlet, which works well for low- to medium-viscosity fluids and simple bead patterns. A tapered tip narrows gradually toward the outlet, which lowers the pressure needed to keep thicker or filled materials flowing. As viscosity or filler content increases, a straight bore is more likely to clog or require higher dispensing pressure than a tapered one at the same gauge.

Yes. UV-blocking tapered tips are widely used for UV-curable adhesives that are sensitive to ambient light. When material sits in the tip near the outlet, even indirect light exposure can begin the curing process and gradually reduce flow consistency or cause blockage. Black tapered tips reduce that exposure. It also helps to minimize idle time between shots and verify residence time during process development.

Tapered tips can be used with some cyanoacrylate adhesives, but suitability depends on the formulation, viscosity, selected gauge, and allowable material residence time. Higher gauge numbers have smaller inner diameters and greater flow resistance, which can increase the risk of partial curing or blockage when CA remains in the outlet between dispensing cycles. Minimize idle time, replace tips as needed, and confirm compatibility with the specific adhesive under actual process conditions before production use.

Standard PP tapered tips are the default choice for most epoxies, silicones, and general adhesive dispensing. Switch to a UV-blocking version when the material is UV-curable or otherwise light-sensitive, since even brief light exposure at the outlet can start premature curing. Choose an anti-static version when dispensing near ESD-sensitive components, such as populated PCBs, where static discharge from the tip itself is a risk. Confirm gauge availability for your chosen material with the sales team, since not every gauge is necessarily stocked in every material option.

Use the bent version when the dispense point sits behind a housing wall, under a fixture edge, or anywhere a straight approach would compromise control. The 35° bend helps maintain a more natural dispensing angle. For open-surface applications, the straight version is usually the simpler choice.

Yes. Btektech tapered tips use a double-helix, Luer lock–compatible thread designed to fit standard Luer lock syringe barrels and dispensing valves. For critical processes or less common valve interfaces, confirming fit with a sample is recommended before switching over a production line.

Higher gauge numbers correspond to a smaller inner diameter and a finer bead, but they also increase flow resistance. Start from your target bead width, then check that the material’s viscosity and filler content can still flow at that gauge without excessive pressure. When in doubt, testing one gauge finer and one gauge coarser than your initial estimate is the fastest way to confirm the right fit.

Yes. Length, bend angle, orifice size, color, and material type can all be customized when the standard range does not fit the process. It is best to define viscosity range, bead width, pressure limit, filler profile, and access geometry before requesting a custom version.
