Dymax T20-125-TT-50 Free-Flow Taper Tips (Pink) (Sold In Packages Of 50)
Dymax T20-125-TT-50 Free-Flow Taper Tips (Pink), Pack of 50
The Dymax T20-125-TT-50 is a 20-gauge pink free-flow taper tip designed for precision dispensing of medium-to-high viscosity fluids, including UV-cure adhesives and light-curable materials. Molded from polyethylene with a UV-light block additive to protect photosensitive fluids from premature curing during dispensing. At 1.25 inches (31.75 mm) in length with a 0.023 inch (0.58 mm) inner diameter, these tips are suited for controlled, fine-deposit dispensing in electronics assembly, medical device manufacturing, and optical bonding. Lead time is 1–2 weeks. Sold in packages of 50.

Frequently Asked Questions
What is a free-flow taper tip and how does it differ from a needle tip?
Free-flow taper tips have a tapered, conical shape that gradually narrows to the dispensing orifice, allowing medium-to-high viscosity fluids to flow smoothly without the back-pressure buildup that can occur with straight needle tips. They are preferred for UV adhesives, epoxies, and other thicker materials where consistent flow and minimal clogging are important. Needle tips are better suited for very low viscosity fluids requiring fine, precise placement.
Why does the T20-125-TT-50 have a UV-light block additive?
UV-cure adhesives and light-curable coatings will begin to polymerize if exposed to ambient UV light during dispensing. The UV-light block additive in the polyethylene tip material prevents light from passing through the tip walls, protecting the fluid inside from premature curing. This is essential for maintaining consistent viscosity and flow during production runs with Dymax and other UV-cure adhesive systems.
What gauge tip should I use for my application?
Tip gauge selection depends on fluid viscosity and required deposit size. The T20-125-TT-50 (20 gauge, 0.023" ID) is suited for medium-to-high viscosity fluids requiring a fine deposit. For lower viscosity fluids or larger deposits, the T18-125-TT-50 (18 gauge, 0.033" ID) provides a larger orifice. Contact MTE Solutions or the Dymax Application Engineering team for assistance selecting the optimal tip for your specific fluid and application.
Are these tips compatible with the Dymax SD-200 dispenser?
Yes — Dymax free-flow taper tips are designed for use with Dymax syringe dispensers including the SD-200, and are compatible with standard Luer-lock syringe fittings. They work with 3cc, 5cc, 10cc, and 30cc syringes. Always verify tip-to-syringe compatibility based on the Luer fitting type before ordering in volume.
