Key Features & Benefits
🩷 Pink Color-Coded Hub
Instantly identify the correct gauge in busy work environments — the pink hub is the universal color code for 18 GA dispensing needles, eliminating mix-ups and saving critical production time.
|
💧 Fine Precision Flow Control
The 0.038" inner diameter delivers consistent, controlled fine-gauge material flow with repeatable results — ideal for low-to-medium viscosity adhesives and sealants requiring precise, accurate placement.
|
🔒 Secure Sem-Luer Lock Connection
The Sem-Luer Lock fitting provides a secure, leak-free connection to Semco® cartridges and dispensing equipment — no slippage, no material loss, no interruptions to your workflow.
|
🔩 Industrial-Grade Stainless Steel
Robust stainless steel construction resists corrosion and chemical exposure — guaranteeing longevity, consistent performance, and extended use in demanding industrial and aerospace environments.
|
📏 Compact 1/2" Length
The short 1/2-inch length minimizes pressure drop across the fine 18 GA bore — engineered for tight spaces, confined assemblies, and applications where compact needle geometry is essential for precise material placement.
|
⚙️ Manual & Automated Compatible
Optimized for both manual and automated dispensing systems — delivering reliable, consistent fine-gauge performance across hand-operated guns and high-volume production environments alike.

Tips for Best Results
✓ Choose the 1/2" length when working in tight, confined spaces where minimal needle profile is critical
✓ Always cap needles when not in use to prevent tip clogging and material waste
✓ Inspect before each use — replace bent or clogged needles immediately to maintain fine-gauge dispensing accuracy
✓ 18 GA is best suited for low-to-medium viscosity adhesives and sealants for optimal fine-gauge flow performance
✓ Confirm Sem-Luer Lock compatibility with your dispensing equipment and cartridge system before use
