They sent the new O-rings for $0. This is a much better price when you have multiple ones (I think we have 5 we use somewhat regularly?)

My Mojave box has a "Gamma lid" so I guess it should have a rubber seal.... Aww shit!

I called them and they said send them an email to their service account. It's been three days without a word. Do you happen to remember who you contacted there?

I just heard back from Gamma and they said they don't normally stock them but are willing to cut me a deal. 50 seals @ 1.70 each ($85 shipped). Obviously, I don't need that many so my first inclination would be to ask if others want some.

That being said, their o-rings are actually different from a standard o-ring. They are hollow o-rings - tubular if you may. They say that this creates a better seal between the top and the ring attached to the bucket. I'm not 100% convinced on this.

Anyway - it's clear that their current o-ring is not that great and it would seems that we would want either 1) a smaller diameter or 2) more resilient o-ring.

Anyone use an alternate solution (solid o-ring) that is water tight?

I've got a fair number of these tops so it's worth it for me to consider repairing rather than replacing.

The gamma lid oring is actually just o-ring cord spliced I believe. At least mine are. If you look close you can see where the ends are glued. You can buy oring cord sold by the foot of various types. Guessing Buna-N might be the best option. Silicone would take a higher temperature but not sure it would hold up as well. I've never tried making my own orings, so cannot claim they will take the abuse. This website was the first to come up on google, but might be a cheaper option out there.

I just had 2-3 leak on Deso so I’d be in for several if you end up ordering them. I was thinking about ordering these:

They say they are better rubber and actually cheaper if you order a few than Gamma’s “deal” but there’s only one way to find out. I find it ridiculous they wouldn’t stock one of the three parts that make up this thing.

I’m also wondering if just putting a bead of silicone on the flat part where the screw top meets the seat wouldn’t do the trick.

Yup, it can be done. We used to make custom O-rings where I used to work. From roughly the size of a gamma seal to about 3' dia (about 1/2" thick). Not hollow though, they were solid and I think if I were to make a gamma seal O-ring, I'd rather make it solid, anyway.

Here's a short video that shows how to do it with a jig you can buy (from the website above), but you can also do it the way I describe below.


Anyway, all you do, is take a NEW single edge razor blade, put the O-ring cord on a scrap of wood, then while holding the O-ring firmly, push down with the razor blade (kinda like slicing a block of cheese), trying to make the squarest cut you can. Practice it a few times, til you're getting a good square cut, then take your measurement and make the final cut. Then glue it together with a drop of superglue. I like to use a scrap of wax paper (to keep it from sticking), then hold it firmly til it's set. A little v-block helps center the joint, but it's not necessary. Then gently sand the glue bead (or slight misalignment) on the joint with 200-300 grit paper til it's pretty smooth. Though the joint doesn't often break, they occasionally do, so keep superglue, sandpaper and razor blades in your tool kit.

I use silicon seal on the o-ring it keeps it shape and seals better. I use these buckets for food storage, they seal much better than gamma lids. My only complaint is they seal so tightly they tend to vapor lock when you seal them when it is hot. I had to put a small nick in the o-ring to allow the air pressure to equalize.
