Dispensing

Nordson EFD dispensing needles are the final element of the dispensing system and determine drop size, flow rate and application precision. The range covers straight, bent (45°), tapered, flexible and oval versions in gauge sizes from 14 to 20 (inner diameter 0.48 to 1.60 mm) and lengths from 0.25" to 1.5". Each gauge size is identified by a standardised colour: olive (gauge 14), amber (gauge 15), grey (gauge 16), green (gauge 18) and pink (gauge 20).

⚙ Gauge 14-20, ID 0.48-1.60 mm - higher gauge number gives smaller inner diameter and finer drops

✓ Colour coding by gauge - olive=14, amber=15, grey=16, green=18, pink=20 - immediate identification

⚡ Straight / bent / tapered / flexible versions - straight for standard access, 45° bent for lateral access, tapered for broad coverage

🛡 Lengths 0.25"-1.5" - short needles for tight access, longer for deeper application points

Gauge	Colour	ID (mm)	Available versions
14	Olive	1.54-1.60	Straight 0.5"/1"/1.5", 45° bent, standard tapered
15	Amber	1.25-1.36	Straight 0.5"/1"/1.5", oval, flexible 0.5"/1.5"
16	Grey	1.19	Standard tapered
18	Green	0.84	Straight 0.25"/0.5"/1"/1.5", 45° bent, flexible, tapered
20	Pink	0.48-0.61	Straight 0.25"/0.5"/1"/1.5", 45° bent, flexible, tapered

Typical applications: Precision application of adhesives and solder pastes to SMD components and connectors, applying lubricants and fluxes at contact points in electronics manufacturing, dispensing UV adhesives into small cavities and tight access points (bent needles), broad application of paste-form materials (tapered needles), and use in medical technology and laboratory automation.
