A threadless snap-in accessory, the IsoFlow™ diptube slides into either of our single-piece bulkheads, secured by patent-pending internal o-ring design. The revolutionary fit makes this diptube fully rotational, for flexible positioning at any angle. Plus, it draws down to within ⅛” of your kettle, leaving less liquid behind than any other dip tube on the market. Compatible with both IsoFlow™ and EZ Clean™ bulkheads. Made of 304 Stainless Steel.
