The nozzle is suitable for a standard 2.5cm bottle mouth (such as plastic bottles with the same mouth as , Cola, Kangshifu Green Tea, Uni Green Tea, etc.) (Although many mineral water bottles have a diameter of 2.5, the mouth may not be the same and may not be usable) All nozzles are equipped with straws (tube length is about 23cm, with an error of 1-3cm) Strong acid and alkali, spray water after use. Do not let strong acid and alkali soak the plastic parts inside the nozzle all the time. Otherwise, the life of the nozzle will not be too long Regarding acid and alkali resistance, it is possible, but some solvents that can dissolve and corrode plastic parts are not durable. For example, machine head water can directly corrode plastic parts. If used, the residual solvent inside the nozzle should also be cleaned, and the solvent should not be kept soaking in the nozzle. This greatly shortens the service life of the nozzle Designed with a comfortable trigger handle for extended use, this hand pump sprayer provides a secure grip during long detailing or janitorial tasks.
