Description
The Techcon 406L-9 syringe barrel piston is a white air-operated wiper piston for 6 cc 400 Series dispensing setups. It sits behind the material in the barrel and helps transfer air pressure evenly across the fluid surface, so dots, beads, and small deposits stay more consistent during bench or automated dispensing work.
Where This syringe barrel Piston Fits
This piston belongs with Techcon 400 Series disposable dispensing components used for adhesives, sealants, coatings, lubricants, and other assembly fluids. The white wiper style is chosen when the process needs a tighter seal between piston and barrel wall. That seal helps limit bypass, reduces material left behind at the end of a shot cycle, and gives operators better control when low to medium viscosity fluids need a steady push from a pressure dispenser.
Use it with the matching 6 cc barrel size and a compatible receiver head, tip cap, dispensing tip, or valve feed setup. It is a consumable fluid-handling part, not a mixer, controller, or valve repair component. Keeping pistons matched by size and style prevents wrong-fit parts from entering a production cell during a refill.
How This syringe barrel Piston Helps Dispensing
Air-powered pistons spread pressure across the material rather than letting air tunnel through the fluid. That matters for repeatable deposits, especially when the operator is chasing clean cutoff, steady flow, or less trapped air in the barrel. For maintenance teams, a fresh piston can also help separate a feed problem from a valve, tip, or controller problem during troubleshooting.
