Techcon TS-SS Metal Dispensing Needle, 18 Gauge x 1/2 Inch

Description

The Techcon 18 gauge by 1/2 inch metal dispensing needle is a precision tip for placing adhesives, sealants, oils, solvents, and other controlled fluids from syringe barrels or compatible Luer lock setups. The 18 gauge size gives a larger opening than fine electronics needles while still keeping the bead or dot narrow enough for accurate bench and automated dispensing work.

Where This Dispensing Needle Fits

Use this needle when a process needs a short, rigid metal outlet rather than a flexible plastic tip or tapered nozzle. The 1/2 inch length keeps the dispense point close to the barrel, which helps operators work near fixtures, corners, and component edges without the tip bending under normal contact. It is a good fit for repeat dots, short beads, potting touch-up, low-volume repairs, and automated stations that need a consistent outlet geometry.

Techcon TS-SS precision metal tips are sold in 12 packs and use stainless steel cannula construction with a nickel plated brass hub. Published catalog data show the 18 gauge, 1/2 inch version with a 0.033 inch inner diameter. The all-metal build suits higher-precision work where a molded hub needle may not hold the same tolerance at the outlet.

Dispensing Needle Selection Notes

Select tip gauge by fluid viscosity, desired deposit size, line pressure, and required flow rate. A larger gauge number means a smaller opening, so moving from an 18 gauge tip to a 20 or 22 gauge tip will usually reduce flow and increase pressure demand. If the material strings, pulses, or requires too much force, confirm both the gauge and the needle length before changing the dispenser settings.

Replace the tip when cured material, metal burrs, or accidental bends affect the shot. Keep clean spares near the work cell so a plugged outlet does not turn into a process adjustment. Browse related dispensers, mixers, and nozzles, or visit Techcon for manufacturer background.
