You really don't need those, as others have said ( a couple of times) just pull an inch and a half long piece of electrical tape down over the valvestem so it pushes its way through and stick the ends to the rim. Tighter fit, costs nothing, black to match the rims. Problem solved.

Robert,
If you get a chance, could you provide a brief review of your wheel build...supplier of the rims...spoke count, weight, type of hubs etc?
Lots of guys interested here in wheel building and inexpensive carbon wheels in particular. A mini review with a pic of a wheel would be most
informative.
Thanks

I can testify to this statement...I bought the "valivinators"....they work...also, you don't have to replace them when you flat...nor does the inside one come off when you replace rim tape...

I had forgotten but was reminded when I opened up the tires to put on the electrical tape (waiting for the valvinators) that I had used spoke hole plugs instead of rim tape on these wheels. The lack of rim tape at the valve hole was likely an additional cause of the noise.

C4L, I am happy to oblige, but am missing some information I'm sure you will think is important. First off, 50 mm deep rims, 20/24, C-X Ray spokes and alloy nipple, Bike Hub Store unbranded hubs (78 g wider model up front, 211 g model in rear, for 8,9, 10 speed, rear drilled 16:8), lacing radial front, 8 radial spokes NDS rear, 16 2X spokes DS rear. The problem is I know very little about the rims. They were a unnamed manufacturer's sample that a friend offered me at a good price. Kind of like buying sample size clothing and shoes from the salesman. Since I am treating them as mostly a show piece for special occasion rides (think wooden rims as an analogy), the specifics really didn't matter to me. No long downhills to worry about, although my friend assured me they are modern technology and high quality. Anyway the rims weigh about 500g apiece and are standard width, not 23 mm type. Weight for the pair of wheels sans rim tape and skewers is 1,490 g. Sorry I can't say more, but that is all I have. I had the decals made at www.carbonwheeldecals.com. Let me know if you have any other questions. Front wheel picture below:
I hope this helps.

The other thing I sometimes do is to take heat shrink tubing and shrink it around the valve stem so it doesn't clunk around. Looks cleaner than electrical tape and turns the valve stem black so it color matches a little better.

Where do you get the tubing? How do you specify it?

You can get it pretty much any store that sells anything remotely electronic, even amazon. There are usually 2 dimensions, 1 before, and 1 after shrinkage (huh huh). Just get a calipers and find out what size your valve stem is, get a pair of scissors and a hair dryer and voila!

Not my picture, but winds up looking something like this:
I would have cut it a little longer to cover up more of the stem.

Another temporary solution is to cut a drinking straw to length and slide it over the valve stem. It doesn't look great and it will fall out eventually but it works in a pinch.

Before. The hot air has a hard time getting between the hole and the stem to shrink the portion hidden by the rim.

The downside is that you have to do it to every tube you use. By making the solution part of the rim it is a one time, permanent solution.
