The BetterBottle SimpleFlo™ Valve and BetterBottle Racking Adapters make up the first valve system for carboys and pails that truly addresses the specialized needs of home winemakers and home brewers. This system makes it possible to rack and bottle professionally, without siphons or pumps. The components are constructed of an incredibly tough, proprietary PET that does not stain or impart flavors and is easily cleaned and sanitized. SimpleFlo Valves have a simple flow path, to prevent clogging. They are simple to operate. They are simple to disassemble and reassemble, making thorough cleaning and sanitizing especially easy. And Viton elastomer O-rings, which are amazingly resistant to harsh chemicals, are used to achieve tight compression seals. But that is not all. SimpleFlo Valves are also designed to rotate in BetterBottle Racking Adapters – hoses can be attached even when a carboy is on the floor. And 3/8" OD polyolefin tubing and bottling stems plug directly into SimpleFlo Valves (see below). Description: The BetterBottle SimpleFlo valve can be used in line with hoses or as an outlet for pails and BetterBottle carboys. The valve can be opened for partial or full flow and closed in the blink of an eye. Its wide, simple flow path resists clogging and it can be disassembled and reassembled for cleaning or inspection in a matter of seconds – without tools.
