These handsome Charcoal Black finish soap dispenser pumps will complement any bathroom or kitchen! Rust proof – the pump is made from 304 stainless steel. Lid materials vary. Use them to dispense hand soap, dish soap, lotion, hand sanitizer, or liquid hair care products. We offer threaded and our classic stainless steel soap pump adapter which attaches with a plastic knut. Included is a 4 1/2″ tube, which is the right length for a quart jar. For a pint jar, cut the tube to fit with a scissors. If you are using a half gallon jar or using the pump with a taller container, we also have 6 3/4″ tubes (8 3/4″ with the pump) available. Be sure to cut the tube short enough that it does not touch the bottom of your jar for proper suction. They are made of stainless steel and plastic, painted black. The threading is 28/400.
