A TT-18 needle is a green, 18-gauge tapered dispensing tip used for industrial applications, particularly for controlling the flow of high-viscosity materials like adhesives and sealants. The "TT" stands for tapered tip, and "18" refers to its 18-gauge size.

Key features

• Design: The tapered shape prevents blockage and minimizes "back pressure," ensuring a consistent and smooth material flow.
• Gauge: At 18 gauge, the tip is wider, which is ideal for dispensing thick liquids. For industrial dispensing tips, a lower gauge number indicates a larger internal diameter.
• Material: The tips are often made of polyethylene and sometimes include a UV-blocking additive for light-sensitive fluids.
• Color-coding: The green color is a standard industry indicator for an 18-gauge tip.
• Hub: These tips feature a Luer Lock hub, which provides a secure, universal connection to industrial syringes and dispensing valves.

Applications

TT-18 dispensing needles are widely used in manufacturing and assembly processes for precise and consistent application of various materials, such as:

• Adhesives and sealants
• UV-curing compounds
• Flux
• Gels and potting materials
• Greases and epoxiestape
