Fischer Flip-Tops : Need some?

[Dutto]

I've got 60+ Fischer Flip-Tops littering up my garage so rather than throw them away I wondered if anyone would like them. These are they ....

I don't use them myself because the rubber seal is glued on and I understand that they are not easy to sanitise. I've tried removing the seals and this is what ten minutes work with a Stanley Knife resulted in ...

What I use with my Fischer bottles are these because they are cheap and readily available in France with their seals.

The drawback of my replacements is that the wire is galvanised (rather than being SS like the Fischer ones) and need to be washed and dried before putting them away.

However, if anyone can use the Fischer Flip-Tops I will happily send them to you and rely of you to refund the postage. The whole lot weigh 1.3kg if you want to work out how much the postage will cost you.

Enjoy!

I was surprised at how easily the welded-on rubber on my fliptops came away after an overnight soak in oxi. Admittedly they weren't glued on but might be worth an experiment to see if it helps. It might have just been the soaking rather than the oxi that did it.

I'll give it a go overnight and see what happens.

If the seals fall off then my offer will be withdrawn and I will start using the SS ones instead!

If they're ceramic a rotary wire brush should strip them off with no damage to the cap, a light gauge brush and ideally one in a bench grinder but a drill held in a vice with one of the type that goes in a drill chuck should get through them pretty quick.

Any luck with these?

Just checked and no change!

Will leave them until Monday when I get back from visiting relatives.

Although they look like a ceramic I think they are actually a super hard plastic. This makes the wire-wheel solution a non-starter because it will probably leave scrapes in it; but I'll still give it a go later!

I suppose that the "Good News" out of all this is that the tops would be relatively easy to sanitise because, if I can't get in there with a Stanley Knife, it stands to reason that bacteria would have a hard time of it as well.

At the moment, it looks as if I will be re-making the old offer next Monday!

Tbh I'd avoid using a wire wheel on them if they're plastic, even unglazed ceramics don't come off well (leaves metal on the surface). Solvents might be an option, the rubber should turn to mush and there's a good chance the adhesive also will but so might the cap and then there's tastes... :/ Could be worth trying one in a jam jar of petrol overnight, it's about 50/50 the cap will survive intact and boiling the crap out of them afterwards would probably get rid of any stinky stuff left behind.

Solvent might work...but which one? We have some in work that dissolves concrete....

Yeah, there are some nice gasket removal products that could be ideal for the job but they're a bit pricey for a shot in the dark. I've a friend who's well up on that kind of thing, what reacts with what but I wont see him until sometime next week, will quiz him up on it.

EDIT: Chances are the cap material is acetal which is safe for foods and oils, a lot of fuel line components are made from it (and it's absolutely fabulous stuff for engineering/fabrication).

Funnily enough I sprayed WD40 on the one that was already shredded with the Stanley Knife!

I've yet to go and have a look because I've been away from home and in an hour or so Texans v. Patriots so ....

... I'll report tomorrow on if anything happened.

Many thanks for all the ideas to remove the "glued on" seals, but so far nothing has affected them!

WD40 did nothing and after almost 72 hours soaking in Oxy-Chem the seals are untouched; but very well sanitised!

In view of this, my original offer still stands if anyone needs them!
