Techcon 20 Gauge Plastic Dispensing Needle, 1-1/2 in, Yellow (Qty 500)

Description

The Techcon TS20P is a rigid plastic dispensing needle in 20 gauge with a color-coded yellow Luer lock hub and a 1-1/2 inch working length. The all-polypropylene fluid path suits shops that dispense adhesives, inks, primers, and light oils where a metal cannula could scratch a delicate surface or react with the fluid, sold here in a bulk box of 500.

Where the dispensing needle fits

This needle threads onto any Luer lock syringe barrel or dispense valve used in benchtop and automated fluid dispensing. The 20 gauge bore is a general-purpose middle ground, well matched to low and medium viscosity fluids like cyanoacrylates, solvent inks, conformal coatings, primers, and light lubricants. The extra 1-1/2 inch reach helps place a bead down inside a recess, a bore, or a fixtured assembly on electronics, medical device, and light industrial lines.

How it performs in service

The molded polypropylene body carries the industry-standard color code for its gauge, so operators can grab the right size at a glance across a mixed tip kit. Because there is no stainless cannula, the tip is a good pick for soft substrates and for fluids best kept away from metal. As a rule, the tip inner diameter should be at least five times the largest particle in a filled fluid to keep flow steady and avoid clogging, which makes a 20 gauge bore best for clean, unfilled liquids rather than heavy pastes.

Dispensing needle specifications

Order the 500-count box when a line runs a steady volume of 20 gauge tips and wants a per-piece cost break. For finer or coarser beads, step the gauge up or down within the same TS family so operators keep one hub and color system.
