Description
The Techcon 0.028 inch fan air cap assembly is a replacement set of dispensing valve parts for spray valve setups that need a controlled fan pattern. It supports coating, lubricant, and low-viscosity fluid applications where a flat spray shape covers more width than a round nozzle at the same pass speed.
Where These dispensing valve parts Fit
A fan air cap shapes atomized material at the front of a spray valve. The 0.028 inch orifice is a middle size in many spray setups, giving more output than a fine 0.014 inch cap while keeping better control than a larger 0.046 inch option. It is a useful replacement when a valve begins to spray unevenly, when an orifice edge is worn, or when a process moves from spot coating to a wider band.
Production teams use this style of cap on conformal coating benches, light adhesive spray stations, lubricant application, and sealant passes over small parts. The fan pattern helps operators cover flat areas with fewer overlaps, which can reduce puddling at the edges of a board, bracket, or fixture. The part should be installed with the matching nozzle and valve hardware so the air path and fluid path stay aligned.
How These dispensing valve parts Control Spray
Before installation, clean the valve nose and confirm the old cap did not leave cured material on the seat. After installation, purge into a test area and check both pattern width and edge quality. A streaked fan can point to a blocked or damaged orifice, while a heavy center band can mean air pressure, fluid pressure, or viscosity has drifted from the setup sheet.
For stations using two-part material, keep this component separate from disposable outlet hardware. It is not a mixing nozzle, 2 part mixing nozzle, or jb weld mixing nozzle. It sits in the valve hardware path, where fit, clean threads, and correct port size matter before any material reaches the final dispense tip.
