Techcon 400 Series 3cc Wiper Piston, White

Description

The Techcon 400 Series 3cc wiper piston is a white polyethylene piston built to seal and dispense low-viscosity fluid from a 3cc syringe barrel without drip or waste between shots.

Where a 3cc Syringe Barrel Wiper Piston Gets Used

This piston fits Techcon’s 3cc air-powered barrels in the 400 Series line (barrel family 403LL), the smallest air-operated size in the range and a common pick for precision dispensing of flux, UV adhesive, or light lubricant onto boards and small assemblies. Electronics lines favor the 3cc size when the dose per part is tiny and precision matters more than volume, since a smaller barrel keeps less fluid sitting in the line between refills. Rework benches running several fluid types through the day often keep a handful of 3cc syringe barrel setups loaded side by side so an operator can switch jobs without cleaning out a larger barrel first.

How the 3cc Syringe Barrel Piston Holds Up

The polyethylene body is silicone-free, so it will not contaminate sensitive electronic or medical-adjacent fluids, and the wiping edge keeps the bore clean on every stroke. Being air-operated rather than manual, the piston is driven by the controller at a repeatable rate, so shot size holds steady from the first dispense of the shift to the last instead of drifting with hand pressure the way a manual plunger can. That repeatability is exactly what a precision, small-dose job needs.
