Sealacone Saver Cap, Never waste a tube again! Universally fits all nozzles. Works with Silicone, Caulk, Expanding foam, adhesives & specialist sealants - 3 pk. For trade & DIY – Reusable & recyclable

I knew that in theory this should work. But like most of us I have tried plugging the spout, wrapping clingfilm around it etc etc. and I have never had great success.However. This works very well. I opened a tube of grab adhesive, used a bit, popped one of these on and about 4 days later the contents was still viable.So very pleased !!

If you're keen on DIY, it's likely you'll have a several tubes of silicon seal, mastic, builders adhesive etc. opened but not all used. This caps are designed to slip over the nozzle and prevent the contents solidifying between jobs.They taper so all sizes of nozzle should fit are are ribbed (Oh, Matron!) so you can pull them off.Bear in mind a pack of 10 nozzles with caps (https://www.amazon.co.uk/Pack-Silicone-Tube-Nozzle-Caps/dp/B01N5D697P) can be had for £3.80. However, with more suppliers using non-changeable nozzles, these have a place.

Like many home users I buy tubes of sealant or adhesive, I use them for a small job and then put them back on the shelf where they may sit for months before I need them for the next job. Invariably the cap does not sit snugly air gets in and the result is a long spout filled with hardened material that has to be coaxed out with a screwdriver and nail. Sealacone has fixed that problem for me, the flexible nature of the device means that air is excluded and I can use the tube over and over again. One tip however is to make sure that you take the pressure off the gun before you put the Sealacone on or you will find that it will slide off, I learned that lesson very quickly.

Amazing! So simple but literally a game changer when it comes to sealant tubes... Put mine in a hole in the gun whilst I'm using the sealant so it's always there to put back on when I've finished. How much time have I wasted fishing out dried up sealant over the years! The screw on caps are useless as they never go back on properly, this fits every time and clears out easily if you get sealant all over it.

I was sceptical about these sealacone things. But now I have tested them for about 6 weeks on a tube of silicon and it's still fresh and usable. I'll be telling all my friends to get a set. Worth the money I'll never need to bin unused hardened silicon again.Now about 3 months since buying first set of these Sealacones and I now want a second set. They keep all but a very small plug of the silicon in the tip usable.

Caps all nozzles really well. Make sure all of the pressure is off before fitting, otherwise you just get a cone full of stuff. I found it worked on everything except for Stixall, which (as it sticks anything!) managed to get stuck!

Oh, how I wish I'd had these a couple of weeks ago when the filler had dried out - though it would have been more useful to have them when I actually recapped the filler. The claim for these caps is that it will keep your sealant fresh for up to 2 years. (I don't have that time to test it out, but at the moment I'm trying it on my new filler and so far so good.)You get three caps in the pack (roughly £1 a cap at the current price), so you can cap off more than one opened product if needed. The caps are reusable and according to the packet recyclable (though I can't find the recycling information on the packet or tube). Be aware they are only compatible with nozzles up to 18mm in diameter,You do need to make sure you follow the instructions as you must form an airtight seal for it to work. The nozzle you are applying the cap to should be clean and any residue from previous use removed. I'd hang on to the card the caps come in as it has all the information about using and reusing the caps. The cones are quite soft and mouldable and you can turn them a little way inside out (with a bit of a struggle) to help clean them.Overall - very useful things to have in your toolbox or junk drawer.

These caps are so handy! I ordered them for my husband to use on some sealant we had open and they fit perfectly, I also used one on my kids liquid glue, its perfect! No more dried up glue and unhappy kids, these are so useful and really good to help reduce waste and tackle our environmental issue with wasting plastic.
