Techcon TS21-1 Green 21 Gauge Dispensing Needle, 1 Inch, 1000 Pack

Description

TS21-1 needle is a green 21 gauge dispensing needle for controlled fluid placement from syringes, valves, and luer lock dispense setups. The 1 inch length gives operators reach into fixtures and housings while the 21 gauge bore supports medium-flow adhesive, sealant, ink, oil, and process-fluid work.

TS21-1 needle Benefits

• 21 gauge size balances fine bead control with enough flow for many shop fluids.
• Green hub follows common international color coding for easier bench identification.
• 1 inch length reaches into assemblies where a shorter tip cannot place material cleanly.
• Stainless steel tube and molded hub format support repeatable dispensing setup.
• 1000 pack supply fits production benches, kit building, and maintenance stocking.

This needle is useful when a bottle tip is too broad or a shorter dispensing tip cannot reach the bond line. It helps technicians place repeatable dots and short beads with less cleanup around the part.

TS21-1 needle Applications

• Adhesive dots and beads in electronics, signs, fixtures, and small assemblies.
• Sealant, grease, ink, and oil placement in production or repair stations.
• Fluid dispensing through compatible syringe barrels and dispense valves.
• Prototype and test work where a standard luer lock needle is easy to change.
• Bench stock for teams that use several needle gauges by color.

Surface Preparation And Use

Confirm material viscosity, bead size, and dispense pressure before running production parts. Start with low pressure and increase in small steps until the bead is stable. If pressure climbs or dots become uneven, change the needle rather than forcing material through a partially blocked tip.

Keep needles clean and capped until use. For reactive adhesives, discard the needle after the material starts curing inside the tube. For automated dispensing, verify fixture clearance, needle length, and luer engagement before cycling at speed.
