The DP847WH is a white PP plastic 28-410 smooth skirt up-lock saddle head dispensing pump with a 9.25 inch dip tube (2.2 cc output). This pump can be locked in the up position, preventing accidental discharge. This pump is ideal for lotions, soaps, and other products. This closure fits containers with a 28-410 neck finish. The first number is the diameter of the container's opening (in mm). The second number refers to the thread/style/depth of the closure's skirt. 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.
