Revolutionary Colby Valve Permanent Stem Replacement - Effortless Installation from Outside the Wheel! Review

Expensive but works well. 6 months old and holding up strong. Easy to set up and even the jack didn't come off the ground which was flat due to the broken barrel. Installed, inflated and still holding air.

You can actually turn the nut by hand with the valve stem in hand before installation to see the brass piece expand the bushing to seal it in the wheel (just as a test). Remember to loosen again before installing. Don't tighten it with a…

I had a broken valve stem and needed to replace it. I called everyone around and asked what the current price for the replacement was because I couldn't put it back on the bead. I was told somewhere between $30 and $50. Luckily I had heard about this product a few weeks earlier and seen some good reviews. I gave it a try because it would only cost about $30 for two.
