This 30" racking cane functions the same as the plastic racking cane, but has the advantages that come with stainless steel. Stainless steel is more resistant to heat than plastic, so this racking cane can be used with hot liquids (provided a high-temperature silicon tubing is used with it). Stainless steel is also more resistant to scratching and bacterial infection than plastic. This racking cane will work with both 5/16" and 3/8" siphon tubing., although he 5/16" tubing will fit tighter and be more difficult to remove. Make the switch to stainless steel today!
