Designed with a standard 28mm neck size, this trigger spray pump is universally compatible with most 28mm-mouth plastic spray bottles (e.g., 500ml, 1L, 2L bottles commonly used for cleaners, disinfectants, or plant nutrients). Its all-plastic construction—crafted from high-quality, BPA-free plastic—ensures safety for both household use (e.g., kitchen degreasers, bathroom cleaners) and commercial applications (e.g., industrial cleaning solutions, agricultural plant sprays), eliminating risks of metal corrosion or harmful substance leaching.
