Description
These are a white PP plastic 38-400 ribbed skirt down-lock dispensing pumps with 11 inch dip tubes (1 oz output). This closure fits containers with a 38-400 neck finish & work perfectly for our bulk 1/2 gallon & 1 gallon serums that we also sell on eBay (linked below). The first number (38) is the diameter of the container's opening (in mm). The second number (400) 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 & an excellent resistance to fatigue. Dip tubes can be trimmed to fit smaller shorter containers. These pumps will fit all of our 1/2 gallon & 1 gallon sized serums that we currently sell. 1 Gallon Pump Dispenser, 38-400 Fit Standard 1/2 & Gal Containers Lotion Serum
