Description
A pneumatic dispensing valve setup only works if the air line between the controller and the syringe barrel seals cleanly at working pressure. This Techcon 400 Series receiver head is that connection for 3cc barrels, running a 3 ft hose back to the controller and locking on with a quick-connect fitting rated to 100 psi.
Where This Dispensing Valve Component Fits
Techcon’s 400 Series receiver heads pair with digital timed dispensers such as the TS250, TS255, and TS350 controllers, delivering metered air pulses through the hose to actuate the syringe barrel. Conformal coating, potting, and general adhesive metering on 3cc barrels route through a receiver head like this one, since the barrel itself has no air fitting molded in. The 3 ft hose length suits benchtop stations where the controller sits within easy reach of the work fixture.
How the Dispensing Valve Connection Holds Up
The head is a one-piece molded body with a fitted O-ring seal, built for repeated connect and disconnect cycles without leaking air past the fitting. Flexible clear PU tubing carries the pulse from controller to barrel, and the quick-connect end swaps onto a standard pneumatic dispenser without tools. Rated to 100 psi, it holds the pressures typical of syringe-barrel dispensing without ballooning or blowing off the barrel under normal duty.
A 3cc barrel, tip, and this receiver head form the wetted and pneumatic path of a complete dispensing station, and each piece wears or gets damaged independently. Barrels crack, tips clog or bend, and receiver heads eventually lose their seal after enough connect cycles, so most benchtop stations end up replacing these three items on separate schedules rather than all at once. Keeping a receiver head in stock as a spare means a seal failure costs a five-minute swap instead of a stalled station while a replacement ships.
