Techcon RNC028 Round Spray Nozzle Cap, 0.028 Inch Orifice

Description

The Techcon RNC028 round nozzle cap gives a TS5540 spray-valve setup a 0.028 inch cone orifice for controlled spray application of low-viscosity fluids. It serves buyers searching for a dispensing needle option, but it is specifically a round spray cap—not a syringe-barrel needle or general-purpose Luer tip. Match it to the TS5540 round-cap configuration before ordering.

Where This dispensing needle Alternative Fits

RNC028 is the round-cap spare part used with the 0.028 inch TS5540 spray-valve configuration. Techcon lists the complete TS5540-028R valve with a round 0.028 inch spray cap and identifies RNC028 among its matching spare parts. This makes the cap appropriate for maintenance, replacement, and stocked-spare programs on production cells already using that valve family.

The TS5540 system is designed for precise spray application of low-viscosity materials. Its process combines adjustable fluid flow with controlled prespray, atomizing air, and post-spray timing through the compatible controller. The cap establishes the round outlet geometry; final coverage still depends on the installed valve, controller settings, fluid, pressure, and validated process parameters.

dispensing needle Selection Checklist

Confirm three details before ordering: the valve family is TS5540, the required spray pattern is round rather than fan, and the specified orifice is 0.028 inch. Do not substitute RNC028 for FNC028, which is the fan-pattern cap with the same nominal orifice. Also verify that the maintenance callout is for the nozzle cap rather than the complete nozzle assembly or complete spray valve.
