Nordson EFD 7005004 Dispensing Needle Tip, PTFE-Lined, 25GA, 1" L, Pink, 50/Pkg, Optimum Series

Optimum® PTFE-Lined Dispense Tips – Clog-Free Precision for Low-Viscosity Fluids

Optimum® PTFE-lined dispense tips are engineered for accurate, clog-free dispensing of low-viscosity fluids, including cyanoacrylate adhesives and other assembly materials. The PTFE liner inside the stainless steel shaft prevents material buildup and ensures smooth, repeatable microdot deposits.

Why Choose PTFE-Lined Dispense Tips?

• Clog-Free Performance: PTFE lining reduces material buildup for consistent flow.

• Ideal for Cyanoacrylates: Perfect for fast-curing adhesives that often clog standard tips.

• Precision Control: Enables accurate microdot application for assembly processes.

• SafetyLok™ Hub Thread: Provides secure, leak-free attachment to syringe barrels.

• Smooth Fluid Flow: Flush hub design prevents trapped air, reducing dripping and drooling.

Key Features

• Free of flash, burrs, and contaminants for reliable performance.

• Color-coded hubs for easy gauge identification.

• Clear packaging with lot numbers for process control and traceability.

• 360° SafetyLok™ thread for safe, positive attachment.

• Engineered hub flats for quick twist-on/twist-off handling.

Frequently Asked Questions

What's the best dispense tip for syringe dispensing?

There is no one ideal dispense tip for syringe dispensing. The best dispense tip for fluid dispensing depends on several factors, including fluid viscosity, dispensing volume, dispensing speed, and cycle time. Making an informed choice of dispensing tip is a critical part of designing your syringe dispensing system.

What's the difference between a dispensing tip and a dispensing needle?

Dispensing tips are the components used at the end of an industrial dispensing head to apply fluids to coat, seal, bond, and fill parts of an assembly. There are as many shapes and sizes of dispense tips as there are industrial fluids and applications, but there are also some commonalities.

Can I reuse a dispense tip?

Like syringe barrels, precision dispensing tips are designed for single use only. The dimensions make them impossible to fully clean. Any attempted reuse can lead to cross-contamination between like fluids, dissimilar fluids, and even the cleaning material. Worse, particularly in the case of adhesives or high viscosity fluids, the tip could become blocked entirely.
