Weller KDS20TNP Dispensing Needle 20 Gauge 0.024 in Id 50-pack

Product Description

The WELLER KDS20TNP is a tapered tip dispensing needle designed for precision solder paste and adhesive application in electronics assembly and rework. Built from plastic with a pink color-coded body for quick gauge identification, this 20-gauge needle features a 0.024-inch inside diameter and a 1.25-inch tip length. It is suited for controlled, small-volume dispensing where consistent bead size and accurate placement are critical. Each package contains 50 needles, making it practical for bench-level technicians who cycle through tips regularly during production or repair work.

This dispensing needle is used in soldering stations, fluid dispensing systems, and manual syringe setups across electronics manufacturing, PCB rework, and surface-mount assembly environments. The tapered tip geometry helps reduce dripping and provides controlled flow of solder paste, flux, adhesive, or other low-to-medium viscosity fluids. The 20-gauge size is a common choice for fine-pitch work and tight component spacing. Packaging quantity of 50 per pack supports ongoing workflow without frequent reordering.

Key Features

• 20-gauge tapered tip needle for precision fluid dispensing
• 0.024-inch inside diameter for controlled, small-volume output
• 1.25-inch tip length for access in confined board areas
• Pink color coding for fast gauge identification at the bench
• Plastic construction — compatible with solder paste, flux, and adhesives
• Sold in a 50-count pack for continuous production use

Compatibility

Designed as a standard luer-lock style replacement needle compatible with manual and pneumatic dispensing syringes and dispensing systems that accept tapered tip dispensing needles in the 20-gauge size.

Installation Notes

Attach the needle to the syringe barrel using a luer-lock or slip-fit connection, ensuring a secure seal before pressurizing the dispensing system. Verify that the fluid viscosity is appropriate for the 20-gauge orifice to prevent clogging or excessive backpressure. Needles are typically single-use or short-term use items — replace when tip becomes obstructed or bent to maintain dispensing accuracy. Dispose of used needles in accordance with applicable shop safety procedures and local regulations.
