Dispensing Needles TT16G (ø1.25) Dark Gray Opaque are heavy-duty dispensing tips engineered for high-viscosity fluids and large-volume applications in industrial manufacturing, automotive assembly, and potting processes. With a generous 1.25mm inner diameter, these robust needles handle thick adhesives, sealants, greases, and potting compounds with exceptional flow control and minimal pressure buildup.

Constructed from premium dark gray opaque polymer, these needles offer superior structural integrity and chemical resistance, making them ideal for demanding environments. The opaque dark gray material provides excellent durability while preventing UV degradation, ensuring consistent performance even with light-sensitive materials. Their reinforced wall design resists deformation under high pressure, maintaining precise dispensing patterns in both automated and manual applications.

Key Features & Benefits:
✔ 1.25mm large bore – Optimized for high-viscosity fluids and rapid dispensing
✔ Dark gray opaque construction – Enhanced durability with UV protection
✔ High-pressure resistant – Maintains shape under demanding dispensing conditions
✔ Chemical-resistant material – Compatible with solvents and aggressive compounds
✔ Anti-clogging design – Smooth material flow for filled and abrasive media

Ideal for automotive sealants, electronic potting, and industrial bonding applications, the TT16G series delivers reliable, high-volume dispensing performance where standard needles fall short.

Built for heavy flows. Engineered to last.
