LOCTITE^® High Precision HDPE Dispense Needles, Tapered Tip

FAQ

What are dispensing tips and needles and what are they used for?

Tip and needles are designed for precision dispensing of adhesives and fluids in both manual and automated systems. We offer a comprehensive line of LOCTITE^® brand dispense tips and needles, from stainless steel (solid metal or with plastic hub), to tapered polyethylene and flexible polypropylene. All feature a positive locking, helical thread design, which ensures the tip stays put during the toughest applications.

When should I use a tapered tip for fluid dispensing?

The cone shape of tapered dispensing tips helps reduce backpressure, meaning you’ll get a more seamless flow rate and consistent dispensing. Tapered tips are more forgiving to different viscosities, provide a smoother flow of materials, decreased resistance and decreased friction. They’re made of polyethylene (HDPE) so they won't scratch when dispensing on sensitive surfaces. These are the recommended dispense tip style for CAs in nearly all situations.

What does the color coding of the dispense tips refer to?

Tip hubs are color coded by size to help identify the gauge or internal diameter. It’s an industry standard code, so you can always be sure you’re choosing correctly.

How do I select the right dispensing tip or needle?

Dispense needles and tips are selected based on adhesive technology and application. Tapered tips are the most commonly used as they are compatible with a broad range of applications and chemistries, and also do not scratch sensitive surfaces/parts. Stainless steel needles are most commonly used when dispensing in hard-to-reach areas. Needle gauge is selected based on viscosity and the size of the bead or drop.
