I'm modifying a heated kettle as a brewing/bottling kettle, it has a small "coffeepot" style tap on the bottom that is a bit too short to use directly for filling. I've found some decent foodgrade tube to fit on it, but it's a bit too thick on the bottling side and barely fits the bottles. hoseIs it possible to heatshrink a hose like this, google isn't really being very helpful to me today... |

Most of that "Tygon" type tubing will soften up and stretch easier when it's heated. It doesn't really shrink like heat shrink tubing but if it's a tight fit, try heating the end in hot water before you slip it on tap. If you think it may come off, you could secure it with a small hose clamp or tie wrap. Just put the tie wrap on while it's still hot.

I guess i was too vague, the hose fits on the kettle side, and i will clamp it there.
But the outer diameter of the hose is only just fitting inside the bottles, so i would like to shrink the hose a bit at the bottom side.

Sorry, I misunderstood the problem. That type of tubing will not shrink. Maybe if you found a smaller tubing that has an outer diameter close to the same size as the inner diameter of the tubing attached to the kettle, you could force that inside the larger tubing and use it as a reducer to put in the bottles. Note also that this type tubing does come in different wall thickness. A low pressure variety may have the right size inner diameter to attach to the kettle yet still have an outer diameter small enough to fit in the bottles.

It might be better to heat stretch the upper end of a smaller tube...

Heat the end with hot water or heat gun and then stretch the end open by inserting needle nose pliers and then forcing the pliers open. I've used that trick a number of times and it works well. |

I just wish it was as easy to form bell ends in PVC pipe that way. |

I am wondering how thick the walls are and if you couldnt just whittle one end a little thinner.
Get at it with a craft knife and see what you get?...
I would suggest a belt sander to smooth it over afterwards, just dont get fingers too close to the belt, eh?...
I do this sometimes with PVC pipe to get it to fit inside hoses I use on my pond?...
Otherwise, go get a thinner hose that fits inside the thicker one?...

looking at the name of it, it's probably the same bit I had. |
