28/410 black trigger spray pump

The 28/410 black trigger spray pump is a dispensing component identified by its 28mm neck finish and 410 thread profile, commonly used for household, personal care and industrial liquid products. It combines a trigger actuator, a shrouded head and a dip tube to draw product from the bottle and deliver a spray or stream. Buyers should confirm the output per stroke, spray pattern and chemical compatibility with the intended formula, as well as the dip tube length to reach the bottom of the chosen bottle. The closure must match the bottle’s neck thread, and physical samples are advised to verify fit, leakage resistance and actuation feel before bulk sourcing.
