It's a hand-actuated spray pump that fits onto a bottle with a 28mm neck finish. The user pulls a trigger to create a manual piston action, drawing liquid up through a dip tube and expelling it as a spray through a nozzle. The "28mm" refers to the outer diameter of the bottle's neck thread.
Common Notation: 28-410. The "410" denotes the specific thread profile and cap style.
Spray Pattern: Primarily produces a stream or a fine-to-medium mist, depending on the nozzle insert (actuator).
Closure Size: 28mm. This is a medium-sized neck, extremely common for bottles ranging from 8oz (240ml) to 32oz (1L), such as standard spray cleaner bottles.
Output: Varies by design, but typically dispenses 2ml to 5ml per full trigger pull.
Materials:
Body/Trigger/Closure: Polypropylene (PP) or Polyethylene (PE).
Internal Components: Stainless steel spring, glass or plastic bead for the valve, various gaskets.
Dip Tube: Flexible polyethylene, cut to length.

| Industrial: Light-duty lubricants, release agents. |
Confirm Neck Size: Ensure your bottle is truly 28-410.
Specify Chemical Compatibility: Declare your full formula to your supplier. "Chemical-resistant" is not a generic term; specify the chemicals.
Request Spray Nozzle Type: Mist, stream, or adjustable?
Ask About Locking: Do you need a twist-lock feature?
Get Samples: Always test a sample with your actual product for:
Spray pattern consistency.
Trigger feel and durability.
Leakage from the collar or nozzle after use.
Chemical compatibility over time (run a stability test).
In summary, the 28mm trigger sprayer is a versatile, cost-effective dispensing solution for a massive range of liquid products. Its success hinges on correctly matching it to your bottle and, most importantly, ensuring full compatibility with the chemical properties of your formula.
