Dangers of Presta Valve Core Removal with air in the tire

One of our viewers comment: ”I heard it is dangerous to remove a Presta Valve Core. Is this true?

Well, that depends. Most of the time, no problem. But if the tire is filled with air as maybe the case with a broken core tip on a clincher or a clogged valve core on a tubeless tire, the air released may cause the valve core to become a dangerous projectile.
00:44 Let’s demonstrate using some long nose pliers.
01:14 To solve this, don’t use pliers or those valve core removal tool similar to Park Valve Core Removal Tool but rather one that hold the end of core, surrounding it to keep it from flying off, such as the Stan’s No Tube Core Removal Tool or the Motion Pro. If the valve is on very tight, use long nose pliers to loosen the core, then continue with a core removal tool such as those mentioned. When removing the valve core in any of these cases also:
1. Use Eye Protection
2. Put the valve at 12 o’clock (facing down and away which also allow the remaining sealant to gravitate to the bottom away from the valve.
3. And as we’ve mentioned, use a valve core removal tool encompasses the end of the valve tip.
