I'm working with a community darkroom that has way more tanks than sealing rings (gaskets). The tanks are all of the universal type, and have the sealing ring with the inverted "L" cross section. I've internetted this at length, but can't find replacements. I'm trying to help economize as much as possible, and hate to chunk good tanks for want of the simplest component.

Anyone know of a source for these?

One could form/cast a new seal from curable resins that change into rubber.
I doubt though that the hassle and costs actually are worthwhile.

Taping the slit after loading could form a makeshift solution.

Or a slice of a (inflatable) tube of proper diameter.

It would help to know what exact tank you are referring to, as I believe "universal" was applied to more than one: http://www.photomemorabilia.co.uk/Paterson/Developing_Tanks.html

I've seen them marketed under several different brand names (Omega, Arista, Samigon, probably others as well), but I think they're probably all made by the same manufacturer, or at least if it's several, they're all using the same molds as they all have the same fluid filling guidelines, and "Made in Spain" molded on the bottom of the tank. Here's the Arista from Freestyle.

Everything "made in Spain" would be by the manufacturer AP. At the moment they even offer two different tanks, seemingly one Jobo-, the other Paterson-style.

Yes, it should be AP.
Their website lists 3 models of 2 designs: one is based on the Paterson System 4 and the other on the Paterson Super System 4.
I don't see any Jobo lookalike.

What Jeff has seems to be a copy of the old Paterson System 4.
You might find the seal ring with Freestyle or others in your country or you can write to AP and see if they'll sell you directly some seals.

See here my System 4 and Super System 4:

My fault!
I was so fixed on those balls that I did not realize that the one I thought to be Jobo-reel style lacks those thumb-recesses.
Also at third look there seems to be a ball too...
