Techcon 20 Gauge Stainless Steel Dispensing Needle, 1/2 in (Qty 12)

Description

The Techcon TS20SS is a stainless steel dispensing needle in 20 gauge with a 1/2 inch cannula and a Luer lock hub, supplied in a box of 12. The precision-ground stainless tube gives a clean, burr-free cut that lays down a consistent bead of medium viscosity fluids in electronics and precision assembly work.

Where the dispensing needle fits

This needle fits Luer lock syringe barrels and dispense valves on manual, semi-automatic, and robotic fluid dispensing stations. A 20 gauge bore handles medium viscosity adhesives, epoxies, cyanoacrylates, UV cures, and RTV in controlled dot and line deposits. The short 1/2 inch length keeps the tip rigid and accurate for close-in work where a longer needle would flex, common on PCB assembly, sensor bonding, and small potting jobs.

How it performs in service

Techcon grinds the stainless tubing to a burr-free edge and crimps it into a locking insert molded into the hub, so the cannula stays put under dispense pressure and does not spin loose from the barrel. Stainless resists most solvents and cleans up for reuse. Match the gauge to the fluid: a 20 gauge bore suits unfilled or lightly filled liquids, while thicker greases and filled pastes want a larger bore to hold flow steady.

Dispensing needle specifications

Order the 12-count box for a workstation that changes tips often or runs several gauges side by side. Step to a finer gauge for smaller dots or a larger gauge for thicker material while keeping the same Luer lock system.
