Description
The Techcon TS20 dispensing needle delivers precise, low to medium viscosity fluid control in a color coded 20 gauge format built for repeatable production dispensing. Each needle is cut from stainless steel tubing, ground burr free, then crimped into an aluminum locking insert and molded into a yellow polyethylene hub, so gauge identification stays fast on a busy bench or automated dispensing station.
Where This Dispensing Needle Fits
This tip mounts to any Techcon syringe barrel through a standard luer lock connection, making it a common choice for adhesive bonding, potting, conformal coating, epoxy dot placement, flux application, and general fluid metering across electronics assembly, medical device manufacturing, and light industrial bonding lines. The 0.5 inch length keeps the needle short and rigid for straight line dot and bead work, and the burr free stainless tube protects fine pitch components and delicate substrates from scratching during close tolerance placement. Assemblers running mixed gauge stations rely on the yellow hub to grab the right size without stopping to check a label, which matters when a line switches between adhesive viscosities several times a shift.
How It Performs
Internal diameter runs 0.024 inches (0.61 mm), a size that balances flow rate against bead control for adhesives and epoxies in the low to mid viscosity range. The needle is rated to a maximum operating pressure of 100 psi (6.9 bar), enough headroom for most pneumatic dispensing setups without deformation or seal failure at the luer connection. Because the tube is precision cut and deburred rather than sheared, dot placement stays consistent from the first unit in a production run to the last, cutting the touch up work that comes from ragged or inconsistent tip openings. The rigid straight profile also holds its shape under repeated cycling, so bead width does not drift as a shift wears on.
