Gaskets Replacement for Glass Meal Prep Containers Universal Sealling Ring Replacement for Glass Food Storage Containers' Lid, O Ring Replacement for Lids

It is not "universal" as being claimed. Also the price is high for a 4M silicon strip.

Not worth at all. The thickness doesn't fit into standard lunch boxes lids. Absolute waste of money for us to buy such expensive replacement gasket. Could have very well bought another new lunch box

Very loose and thin. Not worth the price.

Not worth to buy not fit for all container

Not for borosil square tiffin

I wasn't able to find a replacement for my Glasslock gaskets at the official Glasslock site. But this worked great as a substitute as an aftermarket product. Fits the Glasslock fine. You just insert into the lid to measure and cut with scissors. The original gasket rips when you take it out to clean it due to food and mold growth.....so new ones are needed. The only downside is that there is a cut, so it isn't a singular circular gasket. But we fix this issue by using saran wrap to prevent food from entering the cut area. It works and becomes super leakproof. Good product!

Me fue 100% funcional. Ya mis tapas tenían el sello negro ahora se ven de nuevo como nuevas y los alimentos sello conservan muy bien.

Great for what I needed. My cats somehow got to the original gaskets and these fit perfectly. Just trim to size (cut a tiny bit more than what u need and slowly adjust and trim to fit your lid) and slowly press it in. Super easy and quick to install. It's not 100% airtight and when I press on the lid you can hear some air squeeze out. So, I don't use the repaired lids for items I'm storing in an "airtight" container but I do use them to pack same-day lunches, etc. and no leaks/dripping! They've lasted several rounds in the dishwasher as well without popping off or coming lose!

Bought this to put a replacement gasket on a round handmade teapot lid. Formed a circle, cut strips from another piece to slot and glue into the open ends of the channels to securely attach the ends into a circle. Taped the joined ends onto a couple of cocktail sticks with insulating tape to hold the ends together till the silicon glue dried. You do need a tube of silicon glue. Worked a treat. Holds on lid just with friction. Plenty left for next seal replacement.

This revived my dollar store tupperware when the old gasket disintegrated and fell out. Very good quality and fits a wide range of groove widths.
