This guide explains why Terumo needles are colour-coded, what the "G" gauge number means, and how to choose the right size — written for buyers across the UK, EU, USA, Canada, Middle East, Asia-Pacific, and Africa.

Why Terumo Needles Are Colour-Coded (Global Standard)

Terumo follows the ISO-standard colour system, recognised worldwide. This means the same colour represents the same gauge (G) in every major region.

Why Colour Coding Matters Globally

  • Fast visual identification
  • Universal sizing across brands
  • Reduced selection errors
  • Easier stock management for international teams
  • Consistent workflow across borders

Common Global Colour Codes

  • Pink = 18G
  • Yellow = 20G
  • Green = 21G
  • Blue = 23G
  • Orange = 25G

These colours are not regional — they are internationally standardised.

What "G" Means: Understanding Needle Gauge Worldwide

The "G" stands for Gauge, which measures the outer diameter of the needle.

Global Rule: Higher Gauge = Thinner Needle

  • 18G = thick
  • 21G = medium
  • 25G = thin
  • 30G = ultra-thin

This rule applies universally, regardless of country or brand.

How Gauge Affects Performance (Global Use Cases)

Gauge size influences flow rate, pressure required, liquid viscosity compatibility, and precision of transfer.

  • Lower gauge (bigger) = faster flow, thicker liquids
  • Higher gauge (smaller) = slower flow, thinner liquids

This applies whether you're in London, Dubai, Singapore, New York, or Johannesburg.

Colour / Color Gauge (G) Notes
Pink 18G Wide diameter, fast flow
Yellow 20G Medium-wide, versatile
Green 21G Standard general-use size
Black 22G Slightly finer than 21G
Blue 23G Controlled flow, widely used
Orange 25G Fine, precise
Brown 26G Extra-fine
Grey 27G Very fine
Light Blue 30G Ultra-fine

  • Individually sterile-packed

Choosing the Right Gauge for Global Applications

Different gauges are selected based on the viscosity of the liquid being handled.

  • Thicker liquids = lower gauge (bigger diameter)
  • Thinner liquids = higher gauge (smaller diameter)

This ensures smooth, controlled transfer in any region or workflow.
