21 Turbo Turbo to exhaust sealing ring

[Red21]

Where do people obtain the sealing ring that goes between the exhaust manifold & turbo on the 21T
They are no longer available from Renault and the Ebay ones are incorrect sizes/thickness, and other likely sources i.e. Ford, SAAB (GM) , aftermarket suppliers either don't list it or like eBay not quite right.
I have enquired at my turbo supplier who are going see what they can do but in the mean time any suggestions?

Can you get similar gauge copper wire? That would work.

Its a good 3mm diameter crush style seal

Any pic / dimensions? Know a few place I can try Monday

Tried looking, its a metal ring, with an oval hollow profile that sits in a slight groove in the exhaust manifold and and crushes to seal when the turbo it's fitted
Managed to stump Dave when I first met him with "name that part" F###ing #win

Copper is soft and will crush into place anyway, and work harden as it does.

Rich whats the diameter and approx width and thickness of the ring?

This is 18 gauge, I reckon a couple of sizes up would do you, or, machine the flanges flat and use a T3 copper gasket.

Mine didn't have a gasket at all when I took the turbo off. Should there have been one?

Zoom in, the gasket is the ring part

Ive run with and without and not noticed anything really. I then had my surfaces machined flat and fitted the commonly available T3 gasket.

Then I changed manifold and have never had a gasket since.

It all gets so hot and expands so quick.
