Description
The Techcon 18 gauge pink plastic dispensing needle is a 1-1/2 inch luer-style tip for adhesive, sealant, primer, and shop-fluid placement where a flexible outlet is better than a rigid metal cannula. The 50-count pack fits bench work, prototype stations, and production cells that replace tips during changeovers to keep bead size and flow behavior consistent.
Where this dispensing needle is used
An 18 gauge plastic tip gives more flow than fine 22, 25, or 28 gauge needles, so it is useful when the material has more body or the dispense amount is larger than a tiny dot. The pink color helps operators separate the gauge from other tips at the workstation. The 1-1/2 inch length adds reach into corners, shallow housings, fixture pockets, and recessed bond lines while still giving the operator enough control to follow an edge or place a short bead.
Plastic tips are often selected around finished parts because the tube can flex if it touches the surface. That helps reduce scratching on molded plastic, painted parts, coated panels, and delicate assemblies. Use a fresh tip when moving between fluids, after long pauses, or whenever cured material changes the outlet shape. A partially blocked tip can make a stable process look like a pressure problem, so replace the tip before changing controller settings.
How this dispensing needle supports process control
Match the gauge to the actual fluid viscosity, shot volume, and desired bead width. Larger bores reduce back pressure, while smaller bores give finer placement. Keep the same gauge, length, and color in the work instruction after process approval so the line does not drift across shifts. For manual syringe work, level the plunger and test the first bead away from the finished part. For pneumatic dispensing, confirm the tip is seated before applying pressure.
