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.
