18/410 lotion pump

The 18/410 lotion pump is a compact dispensing component defined by its 18mm neck diameter and 410 thread specification. This neck finish is designed to fit bottles with a matching 18/410 opening, commonly used for small to medium skincare and cosmetic containers. Selection considerations include pump dosage, actuator type, material such as PP, and decoration options. The 18/410 specification helps ensure a secure thread engagement, but compatibility should always be confirmed with the actual bottle and physical samples. Buyers should also assess seal integrity, actuation smoothness, and suitability for the intended formula viscosity.
