A white PP 28-410 ribbed skirt down-lock wide head smooth dispensing pump with a choice of a 6.5" or 8.5" inch dip tube. Down-lock pumps, when fully depressed and twisted, can be locked to prevent accidental dispensing. This closure fits containers with a 28-410 neck finish. This pump is made of polypropylene (PP), which means it has a high heat tolerance level and an excellent resistance to fatigue. Dip tubes can be trimmed to fit smaller shorter containers.
