Permabond 25 Gauge Taper-Tip Dispensing Needles

Description

The Permabond 25 gauge taper-tip dispensing needle gives adhesive users a fine tapered outlet for controlled flow from compatible AA, CA, ET, MT, PT, TA, and UV packages. The tapered tip and hub fit the basic Permabond package nozzle, stepping the outlet down to a repeatable bead or dot without switching to a full valve system.

Where this dispensing needle fits

A 25 gauge tapered outlet is useful when the work needs small dots, short beads, or tight placement without the scratch risk of a metal tube. Assemblers use this size for cyanoacrylate, acrylic, epoxy, primer, and UV adhesive packages that already have a nozzle but need better reach or more accurate placement. The tapered plastic body is a good fit where the operator may touch the tip near delicate plastic, coated metal, or electronics work.

The needle is a simple consumable, but it affects dispense quality. A clean, straight outlet keeps the bead centered, reduces scrape marks from a damaged tip, and makes it easier to repeat the same application angle across a batch of parts. Keep fresh tips near the adhesive station so operators do not keep using a clogged or bent tip after the flow pattern changes.

Use notes for adhesive stations

Match the tip to both the package and the adhesive. A dispensing tip controls placement, while a mixing nozzle or 2 part mixing nozzle is used only when two components have to combine before the bead reaches the part. Requests for a jb weld mixing nozzle should be checked carefully because those buyers may need a cartridge mixer, not a single-component needle. Keep the package upright while installing the tip, purge a small amount onto scrap, and wipe the hub before storage. If the bead tails, pulses, or drips after pressure is released, change the tip before adjusting the adhesive process. Write the selected gauge on the job traveler when a repeat assembly depends on a specific bead width, because small changes in outlet size can change squeeze-out and cleanup time.

Choosing this dispensing needle for adhesive packages

Choose the 25 gauge taper tip when placement accuracy matters more than fast material flow. It suits small adhesive dots, edge touchups, and detail work where a coarse tip would flood the bond area. If the process uses a low-viscosity cyanoacrylate or primer, test the bead on scrap first because a fine outlet can raise pressure with thicker materials.

Treat taper tips as disposable process items and replace them when cured adhesive changes the outlet shape or raises dispense force. For adjacent tips, nozzles, syringes, and package accessories, browse dispensers, mixers, and nozzles. For manufacturer background on adhesive nozzles and applicator options, see Permabond.
