Kilner Jar Repair

A bit of simple kitchen repair this week.

A Kilner jar is a brand of glass jar with a toggle clamp style fastener. It typically has a rubber seal between the glass lid and the glass body. Unfortunately after years being exposed to sunlight the rubber had become brittle and was starting to breakup. Some replacement seals were ordered and I set about swapping them in.

The process is pretty straightforward and is a massive saving on buying a new set of jars.

And now the jar is a good as new and will serve us for many more years.

    I have purchased some rubber seals for my jars, but the metal clips are rather tarnished. Can you tell me where I can buy new ones. Regards G Hopper

    Hi. Can anyone tell me a way to remove a harden seal off the jar. Have a vintage canister set about 40+ years old. The seals are dry rotted but still seal, and are stuck on pretty good. They do need replaced, so I don’t want to leave them. Hard time getting them off. Any ideas welcome. Thank you.

  3. how do you tighten the metal clips? mine have become loose with time.

    • I would say that unless it is affecting the seal, not to try to tighten them. You can shorten the metal by putting a kink into the metal or by unfolding and refolding the wires. But you could easily end up with a non functional jar.
      An alternative might be to put something between the wire and the jar. Perhaps a ribbon?

    Where can I buy these seals plse,?

  5. Robert Saunders says:

    don’t worry about the seals, the wire is ordinary steel, not stainless, I contacted Kilner, to ask if I can buy replacements, I was told,” we don’t supply them you will have to buy new jars”. not even an apology. I think it is disgusting.

    I second Robert Saunders comment, I too was looking for replacement wires, it’s shocking they don’t sell these as spares, plenty other storage jars out there, won’t be buying from kilner again with their attitude

      I don’t think anyone sells the metal clip part I am looking for Le Parfait ones. Says they are hand assembled. maybe you need a tool? I have a box or ‘arc’ spare lids that fit some jars thrifted, the silicon seals are widely available for different brands. I want to replace the rustwd steel clips.

      • Seems like there are a number of sellers of the wires on Ebay. Search for “Mason Glass Jar Lid Wire Clamp Replacement”.
        I think all you would need would be some pliers to swap them.

          The Mason wire closures are too small. No-one is selling the right size for Kilner jares, despire there being many jars of the same type and size fore sale. I expect it will take an enterprising Chinese firm to manufacture them!

    i was gifted a Kilner Jar but the front clasp to close it is missing. Do you know where i can purchase a Clasp?

    How do you loosen the snap ? When I go to seal I feel like the glass is going to break.
