This kit is Short and Sweet! This weldless kit can be used for whirlpool or dip tube setup. The high flow 90 allows maximum flow to go with the 1/2" ID silicone tubing that is commonly used. This whirlpool kit is a little different from our other design that doesn't use a valve. The design requires a valve since it's going low enough where it will be under the wort level. You can choose from a 2pc or 3pc ball valve for the kit. The fittings are not installed due to the fact that teflon tape and installation to the kettle are required.
