Hi all,
I'm looking to replace the tenon corks on my Festival. After 4+ years in daily fluctuations of Florida weather, they're staring too crack apart. My question: Who here has experience with synthetic tenon corks? Not necessarily the cheap, fake stuff that sort of looks like cork -- I'm more referring to the black synthetic material that I've seen some repair techs use on pro overhauls. Anyone have experience with this stuff (or that could even point me in the direction of an exact brand/product?) Just wanted to get some ideas before I replace the cork with the usual stuff. Thanks!

I dislike the synthetic corks - they don't always last as long. Sometimes glue doesn't stick to them so well, and I've seen them deteriorate and start to break apart. Most new clarinets use synthetic cork on the tenons and peel and stick synthetics for all of the key corks - and it doesn't last - terrible stuff. I've had some of that junk fall off of brand new clarinets in the first month or 2 of playing.
I recommend using natural tree cork, and contact cement.

And a good quality cork grease.

How about the tenon corks on Divine clarinets? Are they good and are they available somewhere else?

I also like to compress the cork strip before fitting to the tenon recess.
Squeeze a few times between 2 smooth boards in a vice, or use a roller (e.g. any tool with a smooth, even, heavy handle) .
The cork becomes more pliable, less likely to crack, and you have taken up some of the initial compression that would otherwise have to happen when fitting into the socket.
And yes, good cork grease

I've never had satisfactory results with synthetic cork, and it doesn't always react well with some types of cork grease.

If the black cork is the Kraus stuff, I've used it, along with several other types of synthetic cork. It has some good properties but I still prefer natural cork for tenons and so far haven't seen a synthetic cork that I liked enough to use.
Good quality natural cork can last a very long time when using good glue and grease that doesn't ruin it. After about 15 years, most of the corks on my clarinets are still original.
