Clear Vinyl Tubing - 1/4" ID (Per Foot)
This clear vinyl tubing is food-grade quality and is approved by the FDA. It has an inside diameter of 1/4" and is very flexible even when cold.
This size of tubing is good if you want to transfer the wort or beer slowly. It handles temperatures of up to 175 F°. Silicone is better than vinyl for transferring liquids at higher temperatures.
Note: Tubing is priced and sold by the foot. For those of us who think in metric 1' is equal to 30.48 cm.
