The kit comes with the plastic collar that attaches the lid to the pump 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 (most are wide mouth) or using the pump with a taller container, we also have 6 3/4″ tubes (8 3/4″ with the pump). Just leave us a note at checkout or send an email and we will send the longer tube instead.
To assemble, listed from top to bottom: Pump, lid, plastic “nut” screws in under lid, foam liner covers inner lid and nut, then plastic tube. Cut tube to correct length, fill jar with soap, and screw onto jar.
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 finish is dark with copper highlighting at the edges. 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.
