Techcon TE718050PK 18 Gauge Green Dispense Needle, 1/2 Inch, 50 Pack

Description

TE718050PK Needle is a Techcon TE Series premier dispense tip for controlled adhesive, sealant, solvent, and assembly-fluid placement. This pack includes 50 green 18 gauge tips with a 1/2 inch stainless cannula and luer lock hub. Use it when a bench or production cell needs a repeatable medium-flow tip for hand syringes, valves, or compatible dispensing equipment.

TE718050PK Needle Fit

The manufacturer lists this item as a TE needle with 18 gauge size, 1/2 inch length, green color, 100 psi maximum operating pressure, and 50 count quantity. The published TE tip guide also maps green TE tips to 18 gauge with a 0.033 inch, 0.838 mm inside diameter. That geometry makes the tip useful for materials that need more flow than fine-gauge precision needles while still keeping bead placement tighter than a cut nozzle.

TE718050PK Needle Use Cases

Choose this tip for short-reach dispensing where the operator needs visibility close to the part. Typical uses include adhesive dots, primer placement, small bead work, potting touch-ups, and controlled fluid transfer in maintenance or production cells. The 1/2 inch cannula keeps the tip compact, which helps when parts are close to a fixture or when a longer needle would bend.

Selection Notes

Confirm the luer connection, material viscosity, pressure setting, and shot size before release to production. Higher-viscosity fluids may need a larger gauge, higher pressure, or a tapered tip. Thin fluids may require lower pressure and shorter dispense time to prevent excess flow. Always test on scrap or a representative part before setting work instructions.

Ordering Guidance

The 50 pack helps tool cribs stock enough tips for changeovers and cured-material replacements. Keep tips covered and clean until use, then replace them when the bead shape changes or cured material appears inside the cannula.
