What's a "Sun Tea" Jar? It's a sturdy 3 qt. or 1 gallon jar used to make tea in the summertime, by setting it out in the sun to brew. Sold at hardware stores, Wal-mart and similar stores everywhere as a seasonal item, for about $3.
The Sun Tea Jar, or "STJ" has been the starting point for thousands of pumpers. There are two steps to converting the jar into the pump- First, making a practical seal for the mouth of the jar, and then modifying the valve to accept a vac line. PumpToy's STJ Precision Seal made the seal problem a thing of the past, but you still had to modify the valve. No more! This kit does it all. If you can turn a nut by hand, you can convert a $3 Sun Tea Jar into a two-stage cylinder in ONE MINUTE FLAT.
Simply, we modify a standard stj spigot, removing the valve portion- and fit a standard pumping quick-disconnect body fitting in it's place. We send you the three things: The modified valve body with the QDB installed, the male insert for your vac line, and a #STJ Precision Seal. The rubber jar gasket and plastic nut are not included, just re-use the ones that came with your jar. Note that not all jars are the same, and to fit the STJ Seal the mouth of your jar should be between 3-3/4" to 4".
You simply unscrew the inner nut (by hand), pull out the old valve, stick in the new- and screw the nut back on! Place the Precision Seal on the rim, connect your pump and you are ready to go. What could be easier?
We now offer several Conversion Kit options, shown below; choose the kit that's right for you!
