Syrup Pump Adapter for Wide Mouth Mason Jars

A friend of mine runs a coffee shop and has started making her own flavor syrups. Rather than having to carefully funnel syrup into old Torani bottles, she wanted to use wide-mouth canning jars - they're easier to fill, and they self-seal as the syrup cools. Then, when they're ready to be used, she can just replace the canning lid with this part, attach the pump, and it's ready to go.

I hacked this adapter together using the threads from kebes22's Syrup Pump Adapter (thing 403831) and coal16
