4.Frequently Asked Questions

Q1: What bottle neck size does an 18/415 sprayer fit?

A: An 18/415 sprayer is engineered for bottles with an 18mm outer neck finish and a 415 thread height specification. It is commonly found on 10ml, 15ml, 20ml, 30ml, and 50ml cosmetic glass bottles.

Q2: Can this sprayer handle viscous liquids like lotions or heavy oils?

A: No. Fine mist sprayers are engineered specifically for low-viscosity, water-thin or alcohol-based liquids such as toners, perfumes, and hydrosols. For thicker emulsions or oils, we recommend our specialized treatment pumps or lotion dispensers.

Q3: How do I determine the correct dip tube length?

A: Provide us with your bottle technical drawings or send us a sample bottle. Our engineering team will calculate the exact bottom clearance (typically 1.5–2.0 mm from the base) and cut the dip tube accordingly.
