I‘m making a brake bleeding system using a hand-held vacuum, and vinyl tubing is needed. The bleeder nipple is 11mm (.433) and there don‘t seem to be any shops around town that carry this size. The available sizes seem to be 3/8 (.375) and 7/16 (.438). Which size would work best? Or, where might metric vinyl tubing be available in my town?
If you gently heat the .375 size tube you should be able to place it on the nipple. Place the end of the tube in hot water for a few minutes, then place it over the nipple. Once cooled, it will grip the nipple sufficient to allow expulsion of the used fluid.
use the 3/8th if you can work it in but if you use the 7/16 you can make a seal washer with flexible foam or rubber make the size to 11mm on the rubber or foam and make a nipple end for the 7/16. You can also buy a kit with plastic powder and make your own adapter for the nipple and any size hose you like. The kit would run you a few bucks, you can even use a candle to melt the plastic once you have what ever you want to make set up. Kits can be found searching the web OKorder has many people selling them.
