Weller 22G Threaded Needle

The Weller KDS2212P is a blunt-tip stainless-steel needle with a Luer-Lock hub. It is supplied in a pack of 50 for use with KDS808 and KDS824A dispensing systems. The 22-gauge needle has an inner diameter of 0.028 in and a length of 1/2 in. The plastic hub provides a secure connection for fluid dispensing applications.

Installation and common issues

The needle threads onto compatible dispensing valves with a standard Luer-Lock connection. No tools are required for fitting or removal. The most common issue is cross-threading the plastic hub if the needle is forced onto the valve. Users should ensure the blunt tip is clear of dried material before each use to maintain flow consistency.

Gauge and compatibility

The 22-gauge size determines the fluid viscosity and deposit volume the needle can handle. It is designed specifically for KDS808 and KDS824A systems. Buyers needing a different gauge or a non-Luer-Lock hub connection will require a different needle specification.

Questions about this item

How can I verify the 22 ga blunt-tip needle is flowing correctly after attaching it to my KDS808 dispenser?

Attach the Luer-Lock hub to the dispenser, dispense a small amount of fluid, and confirm a steady, consistent stream exits the 0.028 in inner diameter without dripping or splattering.

What does the package contain and is anything else required for use with a KDS824A system?

The box includes 50 stainless-steel needles with plastic Luer-Lock hubs; no extra parts are needed — they thread directly onto compatible KDS808 or KDS824A dispensers.

Which gauge and length should I select for a 1/2 in deposition depth with a 0.028 in inner diameter?

Choose the 22 ga, 1/2 in blunt-tip version — it matches the required deposition depth and inner diameter for precise fluid placement.
