Silicone tubing is a bit more expensive, but much more flexible and stretchable. It will likely fit over those oversize nonstandard Chinese knock-off nipples. Taking some fine sandpaper and chamfering the end of the nipple a bit will also help. It still might not be easy; you should try to get used to that going forward in life...
Buying a roll of silicone tubing will likely mean you have invested only slightly more in total than if you had bought good stuff originally...but you "got a deal online"...
