Huge funnel, 4.7 liters (one gallon). Made of polypropylene
To be used with our water filtration kit UNO or a 40 mm in diameter pipe (active carbon filtration unit).
Instruction how to fit the funnel onto a 40 mm pipe: Heat water until it is boiling hot. Take the funnel and submerege the spout of the funnel into the water for a few seconds. This makes the tip of the funnel soft. Take the pipe and push the pipe through the funnel. Let it cool. This provides a tight connection between pipe and funnel. For extra security use a hose clamp to tighten it even more.
