Stainless Weldless Fittings

Stainless steel weldless fittings for homebrewing are a great way to modify your kettle without having to weld.  Our weldless bulkheads are made of 100% stainless steel and silicone.  They all come equipped with high quality silicone gaskets, making them virtually leak-free!  The ball valve is a great addition to any kettle without one, allowing for easier transfers. The whirlpool arm allows you to recirculate your wort with a pump, creating a vortex that will leave most of your hop material in the center of the boil kettle, meaning less sediment in your fermenter.  You can also add a thermometer or sight gauge to almost any kettle with these weldless options!
