An evolution in bottling! This stainless steel bottle filler with spring is the ultimate upgrade for bottling. It is much sturdier than plastic bottle fillers, and being stainless steel, is resistant to scratching and harboring bacteria like plastic. It features a spring-loaded tip that shuts off liquid flow when lifted, and has a 3/8 in. barb at the end to attach perfectly to 3/8 I.D. tubing.
