Techcon TE7 Dispensing Needle, 23 GA Bent 45 Deg, Pack of 50

Description

This Techcon TE7 series dispensing needle pairs a precision-bent 45 degree stainless steel cannula with a double-helix polypropylene hub that locks onto standard syringe barrel threads. Each needle in the pack is electro-polished and burr-free inside the bore, which keeps material flow unobstructed instead of catching on rough edges as it exits the tip.

Where This Dispensing Needle Fits

The 45 degree bend angle reaches into recessed features, tight corners, and angled joints where a straight tip cannot get square to the target surface. Assemblers reach for a bent tip like this for underfill, potting into confined housings, and bead placement along vertical or angled seams on populated boards and enclosures. The bend also keeps the operator’s hand and the barrel clear of the work surface during placement.

How the Dispensing Needle Performs

The 23 gauge bore measures 0.013 in ID, sized for moderate-viscosity adhesives, conformal coatings, and thermal compounds that need a controlled bead width. Silicone-free and chloride-free construction keeps the tip compatible with sensitive electronic assembly work. Maximum operating pressure is 100 psi (6.9 bar) at the hub connection, and the polypropylene hub seats securely on a standard barrel without tools. Technicians working mixed production runs keep a few bend angles on the bench so the tip matches the joint geometry without repositioning the whole syringe barrel for every part.

TE7 Bent Needle Specs

Order this pack when the application angle rules out a straight tip. Pair it with our dispensing valves and mixers for compatible pens and cartridges. For gauge selection guidance by fluid viscosity, see Techcon.
