jackgym Posted May 29, 2023 Share Posted May 29, 2023 Is it necessary to remove the tamper proof ring from the neck of the PET bottle before using the caps a second time? Some brewers say the ring stops the cap from tightening down properly again. 1 Link to comment Share on other sites More sharing options...

DavidM Posted May 29, 2023 Share Posted May 29, 2023 Some remove, some don't. it doesn't hurt to remove, so why not, just to make sure you get a good seal. 2 Link to comment Share on other sites More sharing options...

Why should it stop the caps from sealing? When new, the ring is attached to the cap and it all works fine. After the bottle is opened, the ring drop a little, like half a millimetre or so, so how would it stop the bottle from sealing? 1 Link to comment Share on other sites More sharing options...
jennyss Posted May 29, 2023 Share Posted May 29, 2023 (edited) Oh dear; I am going to go have a bet both ways! Yesterday I filled 30 PET bottles. I had a mixture of: brand new - lids with rings still attached; used - ring still attached to the bottle; and used - ring removed. I felt that I got a tighter seal with the used bottles with rings still on the bottles. This may be just my impression. However, over 22 brews, with a mixture of lids and rings as described above, I have never had a flat/uncarbonated bottle.

If after tightening you can move the ring it is not interfering with the cap. 1 Link to comment Share on other sites More sharing options...

Yes, I agree it is not entirely essential, but when I was bottling, I eventually added different brands from other manufacturers - Mangrove Jacks, Morgans etc. & apart from some being 750ml instead of 740ml they were slightly different shape & colour, & also thinner at the top. Over the years I had the odd one that didn't seal properly so I ended up removing all of the tops. I won't ever be using them again so now I guess it doesn't matter. 3 Link to comment Share on other sites More sharing options...
jackgym Posted May 29, 2023 Author Share Posted May 29, 2023 Thanks fellas. I'm inclined to think it's not entirely necessary to remove the ring. 4 Link to comment Share on other sites More sharing options...
Spursman Posted June 1, 2023 Share Posted June 1, 2023 I removed the rings but not because the seal was affected. My tender little hands were getting ripped by the jagged edges! 1 1 Link to comment Share on other sites More sharing options...
