The Yellow Square 15G dispensing needle screws onto a syringe or dispenser with a Luer Lock interface and applies glue, flux, paste, lubricant or sealant of medium viscosity. Its stainless steel tube is 13 mm long, with a 1.8 mm outer and 1.50 mm inner diameter, on a dark blue thermoplastic base. Overall length is 30 mm.

What you get
- Even flow of paste-like materials — the 1.50 mm inner diameter suits glues and pastes of medium viscosity.
- A threaded fit — the Luer Lock interface means the needle screws on instead of pushing on.
- A stiff steel tube — stainless steel, 13 mm long, 1.8 mm outer diameter.
- A base that is easy to grip — thermoplastic, 17 mm high.
- A color you can spot — the dark blue base stands out among other tips.
- A compact size — 30 mm overall, 0.25 g.
Who it suits
Electronics repair and soldering work, modellers and 3D printing users, jewelers doing small repairs, and household jobs where glue, flux, paste, lubricant or sealant has to go exactly where it is needed.
Who should skip it
For very thin liquids and drop-sized micro doses the 1.50 mm channel may be too wide; a finer gauge is the better fit there. There is no compatibility data for syringes and dispensers without a Luer Lock interface.
Use and compatibility
Compatibility: syringes and dispensers with a standard Luer Lock interface. Use: applying glues, soldering fluxes and pastes, dispensing lubricants and sealants, electronics repair and soldering, 3D printing and modelling, small jewelry repairs, household repairs.
