The pumps come with the plastic collar that attaches them to one of our soap pump adapter lids and a 4 1/2″ tube (6 1/2″ protrusion into the jar including the part of the pump that sticks into the jar), 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 here.
Be sure to cut the tube short enough that it does not touch the bottom of your jar. If the tube is touching the bottom, the plastic collar will work its way off the bottom much more quickly. You can use a drop of super glue between the plastic collar and pump if you find the collar comes loose too often.
They are made of stainless steel and plastic. The satin finish looks like a natural or brushed stainless steel. The threading is 28/400.
In addition to Mason jars, these soap pumps will fit on any standard 1″ threaded bottle, or in any hole that is 27mm or about 1 1/8″. Many liquor and beverage bottles can be upcycled as soap pumps! A few that work are Jack Daniels, Crown Royal, and Jägermeister.
If the lid from a 2 liter bottle of Coke will screw onto your dispenser, then so will these pumps.
