[Nhcoll-l] Does anyone sell 120mm 1 gallon jars anymore?

[Callomon,Paul]

We use 120 mm screw-on PP lids with F217 liners, which we get from Kols. They hold OK, but overtightening can cause the skirt to spread, dishing the lid and potentially compromising the seal. 120 mm seems the upper size limit for flexible screw-on lids; above that, they should either be metal or some other kind, such as clamped or two-piece.
In my experience, the older two-piece 120 mm plastic lids with a separate disk and ring (like 2-piece canning lids, or those on Kilner jars) do a better job. This is because the disk was evenly pressed onto the mating face regardless of whether the ring distorted or not. You can dress the jar rim with vacuum grease, too, which guarantees a good seal. These lids have not been made for many years, though.

External.

My experience is that when tightened, there is a deflection that does not make a good seal.  I do use them, but in many cases I “seal” the jar with electrician’s tape – a nuisance so I avoid using gallon jars unless absolutely necessary.

Paul Larson at the Florida Fish & Wildlife Conservation Commission suggested these lids to me when I had the same question a few months ago.

I haven’t gotten around to ordering them yet, but they use them in FL and the measurements suggest they would fit our 1 Gal + ½ Gal jars here too.

Hello Everyone, I am interested in restocking our 1 gallon glass jars that fit 120mm lids. Unfortunately, I have not been able to find a website that sells them. Can anyone point me to where these are still available? Thank you! Caroline Haymaker,
