Techcon 21 Gauge Stainless Steel Dispensing Needle, 1/2 in (Qty 12)

Description

The Techcon TS21SS is a stainless steel dispensing needle in 21 gauge with a 1/2 inch cannula and a Luer lock hub, packed 12 to a box. The slightly finer 21 gauge bore places smaller, tighter dots and lines than a 20 gauge tip, which suits close-tolerance electronics and precision bonding.

Where the dispensing needle fits

This needle threads onto Luer lock syringe barrels and dispense valves across benchtop and automated fluid dispensing. The 21 gauge bore is a step finer than 20 gauge, good for low to medium viscosity adhesives, cyanoacrylates, UV cure resins, inks, and solvent fluids where a smaller deposit matters. The rigid 1/2 inch length holds its aim for accurate placement on tight PCB, sensor, and small-part assembly work.

How it performs in service

The stainless cannula is ground burr-free and crimped into a locking insert in the molded hub, so it resists spinning loose and delivers a repeatable bead from the first shot to the last. Stainless stands up to solvent flushing and reuse. Remember that a finer bore raises back pressure, so pair a 21 gauge needle with thinner fluids and step to a larger gauge for filled or high viscosity pastes.

Dispensing needle specifications

Order the 12-count box for stations that dispense fine dots and lines. Keep a 20 gauge on hand for slightly larger deposits, or move up in gauge number for the finest work, all on the same Luer lock hub.
