For lower viscosity liquids and pastes such as glue, flux, lubricant and sealant, Yellow Square offers a 16G dispensing needle. It attaches to a syringe or dispenser through a threaded Luer Lock interface. The stainless steel tube is 13 mm long, with a 1.6 mm outer diameter and a 1.37 mm inner channel, on a plastic base.

What you get
- A threaded seat — the Luer Lock interface is threaded, so the needle screws onto the syringe.
- A channel for thinner materials — 1.37 mm inner diameter.
- A slim steel tube — 1.6 mm outer diameter, stainless steel.
- Precise placement — the 13 mm tube lets you bring the tip right to the spot.
- One needle for several jobs — flux, glue, paste, lubricant, sealant.
Who it suits
People who solder and repair electronics, modellers and 3D printer owners who need to dispense flux, glue or lubricant of lower viscosity from a Luer Lock syringe.
Who should skip it
For thick pastes and sealants that are hard to push through, the 1.37 mm channel may be too narrow. There is no compatibility data for syringes without a Luer Lock interface.
Use and compatibility
Compatibility: syringes and dispensers with a standard Luer Lock interface. Use: dispensing flux from a syringe; applying glues, pastes, lubricants and sealants; electronics repair and soldering; 3D printing and modelling.
What's in the box
A 16G Luer Lock dispensing needle. The listing does not state how many pieces are in the pack.
Questions and answers
What viscosity is the 16G needle designed for?
Lower viscosity liquids and pastes. For thicker pastes the line has a wider gauge, and for the smallest doses a finer one.
Can I dispense flux with it?
Yes, dispensing flux from a syringe is one of this needle's main uses.
What are its dimensions?
Outer diameter 1.6 mm, inner diameter 1.37 mm, steel tube length 13 mm. The maker does not give the overall length or base height for this gauge.
Which syringes does it screw onto?
Syringes and dispensers with a standard Luer Lock interface.
