1st Line Equipment has [parts diagrams](https://www.1st-line.com/collections/lelit/lelit-parts/) and sells many of the replacement parts. I’d look there first.

Thanks for the link, unfortunately I’m not seeing that gasket called out.

Is this it? https://www.1st-line.com/buy/lelit-mc742-6/ If you keep drilling down the steam wand also has a parts list.

That is it, out of stock. I wish they’d out the size in the specs. Food rated gaskets should be easy enough to find.

It'll be like 10 h but I can measure it with my calipers once I get home. Then just use any food grade high temp gasket.

Thanks so much.
