Where to get very large food grade O rings?

[cheb]

I need one for a spring form cake tin, 250mm diameter and a 5mm section.

I've spent too long looking for one without success. Frustrating as the rest of the tin is good, it just needs an O ring

where does this said ring go? that will be silicon I reakon

 

[cheb]

There's two metal parts, a base and a circular side bit. The O ring sits in a groove and makes the tin liquid tight. I would think silicon too, at a push I could make my own.

just line the tin like a pro bit of parchment paper round the edge with diagnoal cuts to the bottom then a round bit on top for the bottom

when i was a pastry chef I use to line all my tins this kind of way, not always with the newspaper on the outside but that is great for wedding cakes ect. http://www.susieskitchen.com/how-to-line-your-fruit-cake-tin-like-a-boss/

Thanks.

I can line tins well enough but the O ring makes it easier. It'd need to be food grade and is it possible to glue silicon? I thought one of its properties was that not much stuck to it.

Take away the "food grade" bit and there are plenty of options that are acceptable.

I think EPDM is providing you buy the correct grade, I think it would be cheaper to buy a silicon one
This place is the rolls royce of Gasket and hose suppliers, not expensive either, but its all high end food or Pharma grade so not exactly cheap

What temperature do you cook cakes at? That has to be a consideration as well as the food-safe bit.
