Jiayouy Saxophone Neck Silicone Tube 5 Colour Instrument Accessories for Alto/Soprano/Tenor Saxophone Supersede Traditional Sax Neck Joint Cork Sheet

I bought these to replace the cork on a Yamaha Student Tenor YTS-23 using a Yamaha 4C mouthpiece. Installation of the sleeve directly onto the neck proved to be too small to hold the mouthpiece securely, so I pulled it off and wrapped 10-12 revolutions of white teflon tape (used in plumbing) onto the neck and reinstalled the sleeve.That gave it enough thickness to secure the mouthpiece in the same approximate position as the cork had.Yes you need to use cork grease to slide the sleeve on, especially after adding the teflon tape. But it ended up working out exactly right, as one would expect.

Regular, no es lo que esperaba

I've been struggling to replace the cork sleeve on my Yamaha Tenor. Replacing the cork sleeve periodically is always time consuming and hard to get right. These just went straight on the mouthpiece neck and were immediately functional. They are very slightly too thin so my mouthpiece has a tendency to slide too far onto the neck, which will make the pitch slightly sharp, but that'll be easy to correct by wrapping a little plumbers tape on the neck and then putting the silicone sleeve over that. There is no loss of vibration transfer using these compared to cork. However they don't work for my Soprano sax, because the neck is too thin, and these are too loose on the neck.

I have only used one of these. Used it on a few decades old Selmer AS500 Aristocrat (Taiwan made). That probably makes no difference but maybe you want to know. Their instructions say to use cork grease when installing it. Do so, otherwise it is very hard to install. The only problem I found is after playing awhile the mouthpiece was very hard to remove. I started putting a few drops of olive oil on this silicone sleeve before installing the mouthpiece and find that it is not so hard to remove. For some reason cork grease was just not slick enough. The mouthpiece went on easy enough but was difficult to remove.Anyway this has a fantastic air seal. Really like it. Wish the selection was all black instead of the multi-colors, but not much shows when you are using it anyway. To me this makes cork obsolete. Hope it lasts.Update: After using it awhile it became much easier to remove the mouthpiece and now just cork grease on it is working fine.10-21-23 I have used several of these on my alto saxophones with success. I have had to glue a couple of them on because they slipped around too much.I tried one on my soprano and there is just no way. These are too large for a soprano sax neck.

I thought this would be an easier way to replace the flaking cork on the neck of my tenor saxophone. It wasn't. After stretching the rubber to put it over the neck, it started sliding back when I tried to put on the mouthpiece. There's no way to double up, so you end up with a loose, floppy mouthpiece...and no one wants that.

They're too thick to fit a mouthpiece over, and there's nothing to secure it in place. So when we tried to put the mouthpiece on, it just pushed the silicone further down on the neck. Really bummed; I was hoping they would work as it's a cool idea!

The cork on my alto started to flake and I did not want to spend the money at a repair shop. Saw these silicone tubes, and thought I would give them a try. The fit is very snug. So it takes some effort getting one on the neck. The good thing is that it does not slip and slide around when you put the mouth piece on. Definitely use cork greese before putting on the mouth piece. Other reveiwers have trouble with these tubes because they are trying to put these on tenor and soprano necks. You might be able to get by with a soprano, but I wouldn't try it on a tenor. Look specifically for tenor tubes.

Too small for my tenor; returned.
